Impedance

While evaluating the impedance characteristics of Bourns Inc.'s Thick Film Resistor, specifically part number CRL0805-FW-R100ELF, it is important to compare the obtained data against recognized industry benchmarks. This comparison determines if the component satisfies design requirements. Given that most resistors display variations in impedance based on test frequencies, such analysis is crucial.

At low test frequencies (5Hz - 100Hz) and 1V input, the CRL0805-FW-R100ELF impedance (85.25m - 85.48m) is notably lower compared to the benchmark's average impedance range of 91.73m - 92.07m. As the frequency increases up to 500kHz, the impedance (85.54m - 85.47m) remains relatively stable with marginal fluctuations. In comparison, the benchmark components' average impedance values exhibit a more noticeable decrease, ranging from 91.93m at 500Hz to 77.62m at 50kHz.

From 75kHz onwards, the nominal impedance of the CRL0805-FW-R100ELF maintains a reasonably stable performance above the benchmark average values until it reaches 600kHz. The impedance achieves its peak performance of 85.83m at 700kHz, exceeding the benchmark average of 101.6m. It is important to note that the maximum impedance value stays below the benchmark's highest values until 300kHz, indicating a relatively narrower performance range.

Upon analyzing data at 10 volts, a slightly different trend emerges. For instance, at low test frequencies (5Hz - 100Hz), the CRL0805-FW-R100ELF impedance (93.73m - 91.43m) is above the benchmark average. However, a notable drop in impedance value is observed at 50kHz, reaching 76.66m, which deviates from the expected performance observed at 1 volt. In higher frequency ranges, the impedance exhibits less stability compared to the benchmark average and fails to consistently maintain superior performance.

In summary, the CRL0805-FW-R100ELF thick film resistor presents a more stable impedance performance in the frequency range up to 600kHz at 1 volt, with nominal impedance values generally exceeding the industry benchmark averages. However, at 10 volts, the stability and consistency of the impedance become more unpredictable, exhibiting both above and below average values. This detailed analysis of the impedance characteristics contributes to a more comprehensive understanding of the component's performance and potential suitability for various applications.

Resistance

The CRL0805-FW-R100ELF exhibits impressive performance in terms of series resistance. Upon careful examination at a test frequency of 5Hz and an input voltage of 1V, the measured series resistance stood at a value of 85.25mΩ. Comparatively, the statistical benchmark's average is observed to be 91.71mΩ. The component demonstrates remarkable consistency, as it consistently registers lower series resistance values than the benchmark's averages throughout various test frequencies up to 1MHz. In addition, the performance is noted to remain stable across the entire frequency spectrum. This is an important aspect as it confirms the reliability of the resistor's performance over a wide range of frequencies.

When subjecting the CRL0805-FW-R100ELF to a higher input voltage of 10V, it maintains its commendable performance. At the same test frequency of 5Hz, the series resistance slightly increases to 93.68mΩ, which is closer to the benchmark average. Despite this increase, the component continues to outperform the benchmark series resistance values across various test frequencies. This trend provides evidence of the resistor's capacity to maintain its performance under different operating conditions, such as increased voltage levels, which is an essential consideration for electronic engineers.

In summary, the CRL0805-FW-R100ELF consistently showcases lower series resistance values throughout the frequency spectrum while maintaining stability in performance. These factors combined showcase the overall reliability and effectiveness of this particular resistor, making it a valuable contender for electronic engineers to evaluate during the component selection process.

Inductance

The inductance performance of the CRL0805-FW-R100ELF was analyzed at two voltage levels: 1 Volt and 10 Volts. The results were then compared against the benchmark data to evaluate the component's performance. The importance of inductance analysis lies in its effect on signal integrity, power transfer, and voltage regulation in electronic circuits, as inductance plays a crucial role in determining how well the component can store and release energy within a specific frequency range.

At the 1 Volt test condition, the CRL0805-FW-R100ELF demonstrated mixed results for the series inductance (measured in Henries) across various test frequencies. The inductance values were significantly higher than the benchmark average for test frequencies 50 kHz, 75 kHz, and 100 kHz. The component had a closer performance to the average values in the midrange frequencies, ranging from 100 kHz to 600 kHz. In contrast, the inductance values at test frequencies 5 kHz, 10 kHz, and 20 kHz were lower than the benchmark average, indicating better performance at these frequency ranges.

For the 10 Volts test condition, a similar trend can be observed. The component's inductance values were substantially higher than the benchmark averages at the lower frequency ranges of 5 kHz and 10 kHz. However, the inductance measurements at other test frequencies were either not reported or not available for direct comparison with the benchmark.

It is key to note that higher inductance values may be desirable in certain applications, such as filter circuits or energy storage elements, while lower values may be more suitable for signal transmission or voltage regulation purposes. Overall, the CRL0805-FW-R100ELF exhibits a somewhat mixed performance in terms of inductance when compared against the statistical benchmark. While the component performs better than average at specific lower frequency ranges, the inductance values are generally higher than the benchmark average across most of the tested frequencies. Engineers evaluating this component should carefully consider these findings while deciding on the suitability of the CRL0805-FW-R100ELF in their circuits, taking into account the specific requirements of each application.

Comparative Analysis

The Bourns Inc. CRL0805-FW-R100ELF thick film resistor was thoroughly analyzed and compared to our statistical benchmark data for resistors with the same nominal value. In order to determine whether this surface mount, 0805 (2012 Metric) packaged resistor is an optimal choice for engineers, a detailed examination of the performance attributes was conducted.

Starting with the low test frequency measurements at 1 Volt, where the CRL0805-FW-R100ELF resistor shows an impedance of 85.25m Ohms which is slightly lower than the statistical benchmark's minimum of 76.51m Ohms and average of 91.73m Ohms. A noticeable trend can be observed in a majority of test frequencies, where the Bourns resistor has a relatively consistent impedance compared to the benchmark values. For engineers prioritizing a stable impedance response, it may be beneficial to consider this resistor.

LCR measurements at 10 Volts reveal a similar trend, with most impedance values slightly more than the statistical benchmark average. Notably, the dissipation factor maintains relatively low values across the test frequencies, from a low of 0.01 at 100 kHz up to a maximum of 0.42 at 20 kHz. While this may indicate efficient operation and less energy loss, it's important for engineers to analyze their specific use cases and requirements when making a decision.

In terms of series resistance values, the Bourns resistor appears to deliver a stable performance at different test frequencies. However, there is some variation in the series inductance readings. At lower test frequencies, the Bourns resistor exhibits higher inductance compared to the benchmark, but as the test frequency increases, this discrepancy reduces. This variation in inductance may impact certain applications, and engineers should carefully consider the trade-offs involved.

In summary, Bourns Inc's CRL0805-FW-R100ELF thick film resistor demonstrates stable impedance and series resistance values across various test frequencies. Although the series inductance has some variations in different scenarios, its performance may still be suitable for applications prioritizing stability in impedance response. By weighing the specific requirements and performance trade-offs against the benchmark data, engineers can determine if this resistor is an optimal choice for their projects.
