This surface mount resistor comes in a 2512 (6332 Metric) package. The objective is to compare the performance of this resistor against the provided statistical benchmark and identify the pros and cons of using it in various applications.

Impedance

In this section, we will examine the impedance performance of Susumu's KRL3264-C-R100-F-T1 and compare it to the statistical benchmark for resistors with the same value. Impedance is an essential aspect of a resistor's performance, as it affects the overall efficiency of the circuit by accounting for the opposition faced by alternating current (AC) due to resistance, capacitance, and inductance in the component.

When evaluating the impedance performance at 1 Volt, the KRL3264-C-R100-F-T1 demonstrates various levels of deviations from the statistical benchmark across the test frequency range. At lower frequencies (5-100 kHz), the impedance of the KRL3264-C-R100-F-T1 is slightly higher than the average benchmark impedance. It goes up to 95.41m ohms at 5 kHz, while the benchmark's average impedance at that frequency is 91.73m ohms. In the mid-range frequencies (100 kHz - 500 kHz), the KRL3264-C-R100-F-T1 closely follows the benchmark curve with minimal deviation. This consistency is essential in specific applications that require stable performance across various frequency ranges. As frequency increases (500 kHz - 1 MHz), this component exhibits an increasing impedance trend that surpasses both the average and maximum benchmark values, indicating its capability to handle higher frequencies may not be the best in its class.

At 10 Volts, the KRL3264-C-R100-F-T1's impedance performance tends to deviate more from the statistical benchmark, especially beyond the 200 kHz test frequency. The impedance curve initially stays under the benchmark's average impedance value until around 20 kHz (99.47m ohms), where it starts to rise notably. The most significant deviation can be observed at 700 kHz, where the impedance reaches 94.59m ohms, significantly above both the benchmark's average and maximum values at that frequency (average: 101.6m ohms, maximum: 187.3m ohms). This increasing trend of the impedance at a higher voltage could impact power loss in certain applications.

In summary, the KRL3264-C-R100-F-T1 exhibits reasonable impedance performance at lower and mid-range frequencies compared to the statistical benchmark. However, its impedance values at higher frequencies, especially at 10 Volts, deviate considerably from the benchmark's average and maximum values. The observed performance deviations emphasize the importance of understanding the operating conditions and frequency requirements of a specific application when selecting a resistor to ensure optimal performance and efficiency. Engineers should carefully consider these impedance characteristics and frequency-dependent performance deviations when determining if this component is suitable for their particular application needs.

Resistance

In this analysis, we are evaluating the performance of the Susumu KRL3264-C-R100-F-T1 resistor in comparison to several statistical benchmarks of components with the same nominal value. The resistor has a nominal value of 100 milliohms (100mΩ) and a tolerance of ±1%.

When measuring at a voltage of 1 Volt, the tested KRL3264-C-R100-F-T1 resistor consistently exhibits values higher than the average series resistance for the statistical benchmarks across the various test frequencies. For example, at a frequency of 5 Hz, the resistor has a series resistance of 95.31 milliohms (95.31mΩ) compared to the average of 91.71 milliohms (91.71mΩ) for the benchmark. As the test frequencies increased up to 1 MHz, this trend remained consistent. At a 1 MHz frequency, the KRL3264-C-R100-F-T1 has a series resistance of 95.26 milliohms (95.26mΩ), while the statistical benchmark sits at an average of 93.43 milliohms (93.43mΩ).

When increasing the voltage to 10 Volts, the KRL3264-C-R100-F-T1 resistor exhibits similar behavior in comparison to the statistical benchmarks. While the series resistances for both the tested resistor and the benchmarks shifted, it is worth noting that the tested resistor tended to perform slightly closer to the corresponding benchmarks across all test frequencies. This information is useful for understanding the component's performance under varying conditions, such as different voltages and frequencies, as it helps to determine the suitability of the resistor for specific applications and its ability to maintain stable resistance over the tested operating range.

Inductance

When examining the inductance properties of the Susumu KRL3264-C-R100-F-T1 Metal Foil Resistor, it is crucial to observe its behavior at various test frequencies to gather a detailed understanding of its performance. For instance, at a 1 Volt test frequency, the resistor exhibits a higher series inductance than the benchmark average across all frequency bands, sometimes considerably. Specifically, at a test frequency of 5 Hz, it demonstrates an inductance of 4.343μH, compared to the average benchmark inductance of 3.411μH. In another example, at a test frequency of 1 kHz, the component inductance is 6.14nH, which, while lower than the average benchmark value of 8.074nH, still surpasses the benchmark minimum inductance of 1.837nH.

Investigating the inductance behavior at a higher 10 Volts test frequency reveals some inconsistencies in the Susumu KRL3264-C-R100-F-T1 Resistor's performance across particular frequency ranges. For instance, at a test frequency of 5 Hz, the inductance value increases to 94.55μH, a significant jump from the 1 Volt test frequency measurement. On the other hand, at a test frequency of 100 kHz, the inductance drops to 1.092nH, lower than the 1 Volt frequency test inductance value of 3.864nH. Such fluctuations could potentially impact the overall performance of the resistor in various circuits, depending on the specific frequency domain requirements.

Despite these inconsistencies, it is essential to note that the Susumu KRL3264-C-R100-F-T1 Resistor successfully outperforms the benchmark minimum inductance levels in all test frequencies at 1 Volt and the available measurements at 10 Volts. This information is valuable for electronic engineers, as the effect of inductance on the component's performance should be considered when selecting a suitable resistor for specific applications where inductance plays a crucial role.

This analysis will compare the performance of this specific component against a statistical benchmark composed of other components with the same value within the industry.

Starting with the impedance performance at 1 Volt, the Susumu Resistor exhibits a slightly higher impedance than the average performance of the benchmark components at the same test frequencies. The maximum recorded impedance difference is 25.44m Ohms at the 5 Hz test frequency, which may not have a significant impact depending on the specific application. However, it's important to consider this when selecting the appropriate Resistor.

Throughout the analyzed frequency range at 1 Volt, the Susumu Resistor shows no recorded quality factor, whereas the benchmark components exhibit a range between 0.01 and 2.10. This could be a critical aspect for certain applications, where a higher quality factor would be preferred to improve performance and signal integrity.

When examining the series resistance values at 1 Volt, the Resistor performs slightly worse in comparison to the benchmark components. However, this difference falls within a very narrow margin, ranging from approximately 0.01m Ohms to a maximum of 3.35m Ohms.

The Susumu Resistor's series inductance values tend to be higher than the statistical benchmark across most test frequencies, with the difference ranging from 0.1n Henries to 5.024µ Henries. Some applications might require low inductance values for optimal performance; hence, this should be considered during the selection process.

At 10 Volts test frequency, the Susumu KRL3264-C-R100-F-T1 demonstrates a noticeable shift in several parameters compared to lower voltage tests. At this voltage level, the Resistor performs better than the benchmark at higher frequencies, with impedance values coming close to or below the average benchmark values in certain cases. The extensive range of test frequencies at higher voltages demonstrates the Resistor's versatility and flexibility for using it in a wider range of applications.

In conclusion, the Susumu KRL3264-C-R100-F-T1 Metal Foil Resistor demonstrates slightly worse performance in comparison to the statistical benchmark in certain aspects such as impedance, quality factor, series resistance, and series inductance. Despite these differences, the Resistor's performance shifts in higher voltage scenarios make it a valid option depending on the specific application requirements. Careful analysis and consideration of these factors must be taken into account when deciding if this Resistor is the optimal choice for your engineering needs.
