Impedance

The Bourns Inc. CRL0603-JW-R100ELF thick film resistor is known for its exceptional performance when compared to the statistical benchmark data. Featuring a nominal resistance value of 100 milliohms (mΩ) and an allowable tolerance of ±5%, the impedance measurements of this resistor stand as evidence to its high-quality performance. In this review, we will analyze the measurements recorded at both 1 Volt and 10 Volts across various frequency ranges, comprehensively covering the impedance characteristics of this particular resistor.

When subjected to a 1 Volt test voltage, the CRL0603-JW-R100ELF resistor displays impedance values between 94.08mΩ and 94.26mΩ over the entire tested frequency range, spanning from 5 Hz to 1 MHz. Comparison with available benchmark data reveals that the impedance values for the Bourns CRL0603-JW-R100ELF are consistently higher than average values from the benchmark, which range from 91.73mΩ to 108.3mΩ. Of note, the maximum impedance observed at different frequencies in the benchmark data falls between 104.4mΩ and 245.6mΩ, providing valuable context for our analysis.

Moving onto measurements recorded under an input voltage of 10 Volts, we observe considerable variations in impedance values when compared to benchmark data. Across a frequency range of 5 Hz to 20 kHz, impedance values lie between 82.4mΩ and 101.9mΩ, with a tendency towards slightly higher impedance. However, for frequencies exceeding 20 kHz, the CRL0603-JW-R100ELF resistor registers lower impedance values in contrast to the benchmark data. This discrepancy becomes most significant across the 50 kHz to 700 kHz frequency range. Understanding these variations and differences in impedance values at distinct voltage levels and frequency ranges empowers electronics engineers to optimally select and utilize resistors, such as the Bourns CRL0603-JW-R100ELF, within diverse electrical circuits and applications.

Resistance

The Bourns Inc. CRL0603-JW-R100ELF Resistor, a Thick Film type, presents a noteworthy performance in resistance values across the frequency range compared to statistical benchmark data. This component, with a nominal value of 100 milliohms (mΩ) and a tolerance of ±5%, exhibits consistent series resistance values ranging from 94.16mΩ to 94.25mΩ when tested at 1 Volt and a 5 - 400kHz frequency range, showcasing uniformity within this spectrum.

In the 450kHz to 1MHz frequency range, the CRL0603-JW-R100ELF Resistor displays a slight decrease in series resistance values, observed between 93.96mΩ and 93.83mΩ. In comparison, the statistical benchmark's average series resistance data spans from 91.83mΩ to 93.43mΩ for frequencies between 1k to 1M, representing higher variability than the Bourns Inc. resistor.

Upon evaluating the benchmark's maximum and minimum values at 1 Volt, it can be deduced that the CRL0603-JW-R100ELF exhibits a significantly stable performance. Maintaining series resistance values almost in the middle of the statistical benchmark data, this component consistently stays within the acceptable resistance values, without surpassing the maximum or dropping below the minimum values.

It is important to note that the results obtained in tests conducted at 10 Volts deviate further from the benchmark data. However, since the benchmark data only consists of 1 Volt operational values, it is essential to confine our 10 Volts comparisons to the 1 Volt benchmark numbers while acknowledging potential discrepancies. At 10 Volts, the resistor's values observed are higher at lower frequencies (5kHz to 10kHz), but display increased divergence as frequencies extend from 20kHz to 1MHz.

To summarize, the Bourns Inc. CRL0603-JW-R100ELF Resistor demonstrates reliable and consistent performance at 1 Volt within the 5 - 400kHz frequency range, exhibiting values closely aligned with the statistical benchmark's average data under those conditions. At higher frequencies, the resistor's performance falls slightly below the benchmark's average but yet, continues to operate within the tolerable benchmark range, exhibiting its reliable nature.

Inductance

When examining the inductance characteristics of the Bourns Inc. CRL0603-JW-R100ELF Resistor, we compare its performance to a statistical benchmark consisting of similar components. This allows us to better understand its behavior in different scenarios and evaluate its suitability for various applications.

At a test voltage of 1 Volt, the CRL0603-JW-R100ELF Resistor exhibits a low series inductance of 3.039μHenries when tested at a frequency of 5Hz, which comes close to the average inductance value found in the benchmark (3.411μHenries). Further analysis of inductance values at other test frequencies shows that this particular resistor remains within acceptable limits compared to the statistical benchmark.

At a higher test voltage of 10 Volts, the inductance values report mixed outcomes compared to the benchmark. Series inductance measurements at lower test frequencies, such as 5Hz and 10Hz, are significantly higher than the average values observed in the statistical benchmark (89.45μHenries and 85.13μHenries, respectively). However, when tested at a frequency of 100Hz, the inductance value of 327nHenries falls within an acceptable range of the benchmark's average series inductance of 52.5nHenries at the same frequency.

It is important to assess how these varying inductance results may affect the performance of the CRL0603-JW-R100ELF Resistor in specific applications. Engineers should thoroughly evaluate its suitability for their particular requirements, taking into account both its strengths and potential weaknesses when used in certain situations. This allows for a comprehensive understanding of the resistor's capabilities and ensures the optimal component selection for the intended application.
