In the subsequent sections of this review, we will dive into a detailed analysis of the UCR03EVPFLR100's resistance and inductance, as well as a comparative analysis, to comprehensively understand the resistor’s performance against the benchmark data, making it easier for engineers to assess its suitability for their circuits.

Impedance

When evaluating the impedance performance of Rohm Semiconductor's UCR03EVPFLR100 Thick Film Resistor, a thorough examination and comparison of the component data with the statistical benchmark data are essential. Impedance, which represents the opposition to the flow of electrical current in an AC circuit, influences the performance of electronic components, affecting the overall stability and consistency of the electronic system or circuit. To properly assess the UCR03EVPFLR100 Resistor's impedance characteristics, measurements were taken at 1 Volt and 10 Volts across a wide frequency range.

At 1 Volt, the UCR03EVPFLR100 Resistor demonstrates relatively stable impedance values throughout the entire frequency range tested, exhibiting a minor decrease in impedance as the frequency increases. When compared to the statistical benchmark, the impedance values for the UCR03EVPFLR100 Resistor are consistently lower than the average and show closer proximity to the benchmark minimum impedance rather than the maximum, across all observed frequencies

Upon analyzing the measurements obtained at a higher voltage of 10 Volts, the UCR03EVPFLR100 Resistor displays notably varying impedance values, resulting in increased impedance at higher frequencies compared to the 1 Volt measurements. Once again, the component's impedance values are consistently below the statistical benchmark average; however, this time, they display a more uneven trend throughout the frequency range.

Considering the wide range of engineering applications, the UCR03EVPFLR100 Resistor's impedance performance highlights an overall stability and reliability in maintaining impedance behavior. Nonetheless, although the impedance values consistently fall below the statistical benchmark average, the oscillating performance at the 10 Volt range might raise concerns, depending on the particular requirements of the intended circuitry. Engineers should carefully examine these variations and the comparison data against statistical benchmarks when assessing this Thick Film Resistor for potential integration into their designs, ensuring compatibility with specific application requirements.

Resistance

The Rohm Semiconductor UCR03EVPFLR100 Resistor demonstrates impressive performance compared to the statistical benchmark of similar Thick Film resistors with a nominal value of 100 milli-ohms (100mΩ), and a tight tolerance of ±1%. When measured at 1 Volt across a wide range of frequencies, its series resistance consistently remained relatively close to its nominal value of 100mΩ, indicating a high level of precision and stability throughout the frequency range.

At lower test frequencies (5 kHz - 20 kHz), the UCR03EVPFLR100 exhibits a slightly higher series resistance than the statistical benchmark's average. For instance, at 5 kHz, it measured 88.18mΩ compared to the benchmark average of 91.71mΩ. The component continues to perform close to the benchmark average as the test frequency increases, reaching 88.51mΩ at 20 kHz (versus the benchmark of 92.05mΩ). When comparing these figures to the benchmark data, the series resistance consistently stays below the benchmark averages, making this resistor an attractive choice for those seeking a Thick Film component with reduced resistance.

Moreover, the UCR03EVPFLR100 displays exceptional stability as the test frequency ranges from 20 kHz to 1 MHz. Despite a slight peak in series resistance at 75 kHz (88.54mΩ), it stays relatively consistent across the entire frequency span, offering predictable and robust performance throughout the tested range. In contrast, the statistical benchmark exhibits a more erratic performance as the test frequency increases, with resistance reaching as high as 93.43mΩ at 1 MHz.

When tested at 10 Volts, the UCR03EVPFLR100 presents an increased series resistance at lower frequencies (95.89mΩ at 5 kHz and 94.66mΩ at 10 kHz) compared to the measurements at 1 Volt, suggesting a relationship between voltage application and resistance performance. As the test frequency increases, the series resistance experiences a decline, reaching its lowest value of 76.21mΩ at the 150 kHz measurement. While series resistance rises once more as test frequency increases beyond 150 kHz, this variation should be considered when assessing the suitability of this resistor for higher voltage applications.

In conclusion, the UCR03EVPFLR100 Resistor is an efficient, precise, and stable Thick Film resistor, making it a viable option for electronic engineers seeking a reliable component for their projects. Its notable performance across various test frequencies and voltage applications showcases its adaptability and effectiveness in different circuit designs and operating environments.

Inductance

The inductance of the Rohm Semiconductor UCR03EVPFLR100 100m Thick Film Resistor is a key parameter to analyze when evaluating its performance in various applications. In this review, we will compare the inductance values of the UCR03EVPFLR100 against statistical benchmarks gathered from other components with the same nominal value at different frequency ranges.

Beginning with a low test frequency of 5 Hz, the UCR03EVPFLR100 exhibits an inductance of 3.467µH, which is impressively close to the benchmark average of 3.411µH for components with similar specifications. This similarity in values demonstrates that the UCR03EVPFLR100 can maintain a stable inductance in lower frequency ranges.

However, when the test frequency is increased to 50 Hz, the inductance of the UCR03EVPFLR100 decreases to 943.8nH. This value is significantly higher than the benchmark average of 598.7nH at 50 Hz. This variation suggests that the component's inductance can deviate from the expected norm at certain frequency points, which might affect its performance in some applications.

As we further examine the inductance performance at other frequencies, it is evident that the UCR03EVPFLR100 maintains relatively high levels of inductance across the frequency spectrum. Interestingly, at 100 kHz, the inductance drops to 1.365nH, a value quite lower than the benchmark average of 6.597nH. This reduction in inductance could potentially limit the component's effectiveness in applications requiring higher inductance values.

Conversely, a reversal of this trend occurs at a higher test frequency of 1 MHz, where the inductance of the UCR03EVPFLR100 increases to 1.454nH, fairly close to the benchmark average of 6.152nH. This reversion to close-to-average values demonstrates that the component is capable of providing acceptable inductance performance in some higher frequency ranges.

In conclusion, while the Rohm Semiconductor UCR03EVPFLR100 100m Thick Film Resistor exhibits acceptable inductance performance at certain frequency ranges, it might not be the ideal choice for applications requiring consistently high inductance values across the full spectral range. Electronics engineers should carefully consider the inductance performance of both the UCR03EVPFLR100 100m Thick Film Resistor and the specific application requirements while making their design decisions.

Comparative Analysis

The Rohm Semiconductor UCR03EVPFLR100 is a 100mΩ, ±1% tolerance, thick film Resistor with a composition optimized for the 0603 (1608 Metric) package. To evaluate the performance of this Resistor, it is crucial to compare the component data against the statistical benchmark data provided.

Upon examination of the impedance metrics, the tested UCR03EVPFLR100 Resistor demonstrates an average impedance between 92.07mΩ (at 100 Hz) and 89.14mΩ (at 1 MHz). Remarkably, it outperforms the benchmark when it comes to the 50 kHz to the 300 kHz range. Concurrently, the Resistor slightly exceeds the maximum (104.5mΩ) benchmark at 150 kHz to 950 kHz.

Comparing Quality Factor (Q) values, the UCR03EVPFLR100 Q ranges from 0.1 to 0.3, which barely meets the average benchmark in the 100 kHz to 400 kHz range. Evidently, the Resistor performs lower than the maximum benchmark value in the frequency range of 100 kHz to 750 kHz.

In terms of Series Resistance, the UCR03EVPFLR100 Resistor performs within the average benchmark data range. It is noteworthy that UCR03EVPFLR100 values mostly surpass minimum benchmark resistance levels across all given frequencies. Simultaneously, it falls slightly short in comparison to maximum series resistance benchmark values across the frequency spectrum.

An analysis of Series Inductance components exhibits a general trend of superior performance for the UCR03EVPFLR100 Resistor when compared to the average and maximum benchmark data. At higher frequencies, between 450 kHz to 1 MHz, the Resistor's inductance levels maintain a small difference from the average value, sustaining a relatively consistent inductance value throughout the tested frequencies.

Overall, the Rohm Semiconductor UCR03EVPFLR100 Resistor displays a competitive performance profile when placed against the benchmark data, with impedance and series inductance being its strongest attributes. However, the Quality Factor is somewhat lacking compared to the benchmark values, indicating room for improvement in future thick film Resistor designs.

Throughout the review, we wanted to ensure its performance justifies its usage in various engineering applications.

Comparing the Thick Film Resistor to the benchmarks recorded, it was observed that at low test frequencies, there's a slightly higher impedance value as compared to the average recorded statistics. This indicates that the device can withstand higher loads at lower frequencies. The average impedance value tends to be slightly lower than the benchmark average when moving towards higher test frequencies. Despite the variations in the impedance, series resistance, series inductance, and capacitance, the data shows that the UCR03EVPFLR100 performs well within an acceptable range and can be used in a variety of circuit applications.

Taking a closer look at the performance of the component at 10 Volts, there are variations in its series capacitance and dissipation factor across different frequencies. As the voltage, frequency, and impedance change, the UCR03EVPFLR100 exhibits different characteristics, and still registers acceptable performance levels when compared to the statistical benchmarks.

In summary, the Rohm Semiconductor UCR03EVPFLR100 Thick Film Resistor demonstrates reasonable performance and reliability, making it suitable for use in engineering projects requiring stable and predictable results. However, engineers should carefully consider the specific applications and requirements, as certain performances may not perfectly match up the average benchmarks.
