Throughout the review of the CRL0603-FW-R100ELF Resistor, we consider crucial performance parameters to offer a comprehensive understanding of how this resistor performs within the market. Some of the key pros and cons derived from the analysis are detailed below:

• Achieves stable performance over the various frequency domains
• Offers a small and convenient 0603 (1608 metric) package suitable for surface mounting

We will delve deeper into the individual factors behind these pros and cons, including resistance, inductance, and comparative analysis sections, to provide a balanced and rigorous assessment for engineers considering the CRL0603-FW-R100ELF Resistor for their projects.

Impedance

In this section, we will evaluate the impedance performance of the Bourns Inc. CRL0603-FW-R100ELF resistor and compare it to provided statistical benchmark data. The resistor has a nominal value of 100 milliohms (mΩ) with a tight tolerance of ±1%, indicating a high level of precision and accuracy in its specified resistance value.

At 1 Volt, the impedance performance of the CRL0603-FW-R100ELF resistor is marginally lower than the average of the statistical benchmark across a range of test frequencies. For example, when tested at 5 Hz, the resistor exhibits an impedance of 84.89 mΩ, whereas the statistical mean impedance value is 91.73 mΩ. Similarly, at higher test frequencies such as 1 MHz, the resistor impedance measures 86.18 mΩ compared to the benchmark mean value of 108.3 mΩ. This demonstrates that the resistor has relatively lower impedance performance compared to the benchmark data at both low and high frequencies.

Moving on to the analysis at 10 Volts, the deviation from the statistical benchmarks becomes more significant at certain frequencies. For instance, at 20 kHz, the impedance value of the CRL0603-FW-R100ELF is 95.2 mΩ, slightly deviating from the statistical mean of 92.07 mΩ. The most noticeable difference occurs at 50 kHz, with an impedance value of 77.15 mΩ, which is considerably lower than the benchmark mean impedance of 92.22 mΩ.

Given this insight into the impedance characteristics, engineers contemplating the use of the Bourns Inc. CRL0603-FW-R100ELF resistor in their designs should be aware of its lower impedance performance relative to the provided statistical benchmarks at both 1 Volt and 10 Volts testing conditions across various test frequencies. This information is critical in determining if this resistor is suited to specific application requirements, such as noise management, thermal performance, or power dissipation. Engineers can opt to perform additional tests or consider alternative components if necessary, based on these impedance characteristics to ensure performance consistency and optimal results in their designs.

Resistance

When measuring the CRL0603-FW-R100ELF Resistor at a 1 Volt test condition, the observed series resistance values demonstrated a range from 84.86mΩ at 5 Hz to 85.71mΩ at 1 MHz. It is worth noting that these values are marginally lower than the average derived from a statistical benchmark, which indicates series resistance values spanning from 91.71mΩ at 5 Hz to 93.43mΩ at 1 MHz. The maximum measured series resistance for the CRL0603-FW-R100ELF Resistor was recorded at 85.88mΩ, occurring at 75 kHz, which is substantially below the statistical benchmark's maximum resistance of 113.1mΩ at 1 MHz.

Upon increasing the test voltage to 10 Volts, the CRL0603-FW-R100ELF Resistor exhibited a noteworthy improvement in series resistance across specific frequency ranges. For instance, at the 50 kHz frequency, the Resistor's series resistance was measured at 77.13mΩ, a significantly lower value than the statistical benchmark's average of 92.15mΩ by around 5mΩ. Furthermore, the component's minimum resistance value decreased to 74.58mΩ at 250 kHz.

It is crucial to acknowledge that the CRL0603-FW-R100ELF Resistor operates at a slightly lower resistance level compared to the statistical benchmark. This characteristic may have significant implications depending on the application's specific requirements and potentially impact the overall performance of an electronic system. Nevertheless, engineers can consider the lower resistance values as beneficial for certain applications or enhancing energy efficiency, depending on the context and design considerations.

Inductance

In this section, we examine the inductance performance of the Bourns Inc. CRL0603-FW-R100ELF Resistor based on a comprehensive statistical benchmark, which takes into account other components with similar characteristics. We focus on the series inductance of the component under two test conditions: 1 volt and 10 volts, with an emphasis on the variations in inductance across a range of frequencies. This information is crucial for engineers aiming to select a suitable resistor for their specific application requirements.

At a 1-volt test condition, the Bourns Inc. CRL0603-FW-R100ELF Resistor demonstrates above-average series inductance at low frequencies (below 10 kHz). Specifically, the component exhibits an inductance of 3.376μH at a 5Hz frequency, which is relatively high in comparison to the statistical benchmark's average of 3.411μH. Upon increasing the frequency, the component consistently maintains higher inductance values compared to the benchmark for all test frequencies up to 10 kHz.

When subjected to a 10-volt test condition, the inductance behavior of the CRL0603-FW-R100ELF Resistor remains akin to that observed at 1 volt. The component exhibits increased inductance values at low frequency ranges, with an 89.31μH value recorded at 5Hz. As the frequency rises, the inductance values tend to decline. It is important to note that the component lacks sufficient data for most test frequencies beyond 1 kHz at this voltage condition, which makes it difficult to evaluate its inductance performance in higher frequency ranges.

Overall, the Bourns Inc. CRL0603-FW-R100ELF Resistor exhibits a frequency-dependent inductance profile that is relatively higher than the statistical benchmark, particularly in low-frequency regions. However, the limited data available at higher frequencies under the 10-volt test condition presents a challenge for engineers aiming to use this component in applications that operate at higher frequency ranges or increased voltage levels. To gain a comprehensive understanding of the CRL0603-FW-R100ELF Resistor's inductance performance, additional investigation and analysis should be conducted under various testing conditions.

Comparative Analysis

The performance of Bourns Inc.'s CRL0603-FW-R100ELF Resistor is assessed in this comparative analysis to provide valuable insights regarding its suitability in various applications. The component's performance is compared against a statistical benchmark based on data from other components with the same nominal value. The review takes into account Thick Film composition, surface mounting configuration, and the 0603 (1608 Metric) package of the Resistor.

When examining the Resistor across various test frequencies at 1V, the results show that the CRL0603-FW-R100ELF exhibits higher impedance values than the average of the statistical benchmark. The most significant differences are observed at lower frequencies, such as 5 Hz, where the Resistor measures 84.89 mOhms impedance, versus the benchmark average of 91.73 mOhms. At 1 kHz, both impedance and series resistance increased from 85.74 mOhms and 85.72 mOhms, respectively, and remained higher than the statistical averages across all frequencies.

A peculiar finding was the higher Test Frequency range of the benchmark data compared to the CRL0603-FW-R100ELF, which lacks data in the higher frequency ranges (750 kHz to 1MHz) in the 10 Volts test. In the 1 Volt LCR measurements, the component displayed higher impedance values compared to the benchmark averages in certain frequency ranges. However, a noticeable decrease in impedance and series resistance values was seen at higher Test Frequencies, especially when approaching the maximum test frequency range of 1 MHz.

In the 10 Volts LCR measurements, a significant impedance deviation was observed in the 20 kHz Test Frequency, where the component exhibited an impedance of 95.2 mOhms compared to the benchmark average of 92.07 mOhms. The Quality Factor for the 5k, 10k, and 100k Test Frequencies showed a markedly lower value for the component compared to the benchmark averages. However, the data omits the Quality Factor from 200 kHz and beyond; this makes it challenging to fully assess its performance in higher frequency ranges.

In conclusion, the CRL0603-FW-R100ELF Resistor exhibits higher than average impedance and series resistance values in particular test frequencies and lower Quality Factors in the 5k, 10k, and 100k test frequencies. However, due to the omissions in measurements at higher test voltages and frequencies, the comparative analysis may appear incomplete. Engineering applications considering the use of the CRL0603-FW-R100ELF Resistor should exercise caution and take all these factors into account when assessing its suitability for their requirements.

The review is intended to provide engineers with a thorough understanding of this Resistor's performance for use in their products.

Although the Resistor's nominal value is 100m Ohms, in many instances, it has performed above the average benchmark impedance values, indicating a promising performance in comparison to other Resistors of the same value. However, some cases showed impedance values below the average, which may raise concerns about consistency. Examining the Quality Factor, it fluctuates at various test frequencies and deviates from the benchmark in certain scenarios.

Overall, the CRL0603-FW-R100ELF Thick Film Resistor performs relatively close to the statistical benchmark data in the majority of the test frequencies analyzed. While there are some deviations from the benchmark, it is important to note that no component is perfect. Engineers who intend to use this Resistor in their products should carefully evaluate its performance in relation to the specific requirements of their applications. It would be wise to consider the obtained data in combination with other factors such as tolerance, composition, and mounting methods, among others.
