While there are both pros and cons to the performance of this Thick Film Resistor, it's essential to assess it with respect to specific design requirements. The following sections will dive deeper into the Resistance, Inductance, and Comparative Analysis of the CRL1206-JW-R100ELF in relation to the statistical benchmark data, aiming to provide engineers a comprehensive understanding of the component's strengths and weaknesses.

Impedance

While examining the impedance characteristics of the Bourns Inc. CRL1206-JW-R100ELF, it's imperative to thoroughly compare the performance of this component against statistically derived benchmark data. This approach allows us to efficiently evaluate and determine the component's suitability for a diverse range of engineering applications.

It's essential to note that, when compared to the statistical impedance benchmark at a 1V testing condition, the CRL1206-JW-R100ELF consistently resides within the minimum and maximum impedance value range across an extensive frequency spectrum, ranging from 5 Hz to 1 MHz. For instance, at 50 kHz, it records an impedance of 77.62m Ohms, which falls between the minimum benchmark value of 77.31m Ohms and the maximum of 104.6m Ohms.

When the testing conditions escalate to 10V, the CRL1206-JW-R100ELF maintains its performance relatively well up until 75 kHz. However, beyond that frequency, the impedance values start to diverge from the acceptable benchmark range. This occurs as the component exhibits lower impedance values than expected. For instance, at 100 kHz, it registers an impedance of 66.73m Ohms, where the statistical benchmark average stands at 92.53m Ohms with a minimum of 77.68m Ohms.

This meticulous impedance analysis showcases the CRL1206-JW-R100ELF's performance across varying conditions. While it delivers satisfactory performance in the lower frequency ranges and testing environments, it is imperative for engineers to proceed with caution when employing this component in high-frequency, high-voltage applications. In these instances, it's essential to conduct proper evaluation to determine the component's compatibility with their respective circuits, to prevent encountering undesirable results during operation.

Resistance

An in-depth analysis of the CRL1206-JW-R100ELF resistor, based on the LCR measurements taken at 1 Volt, reveals that its performance concurs with the benchmark data provided for thick film resistors. Significantly, in the lower test frequencies ranging from 5 Hz to 20 kHz, the resistor demonstrates excellent consistency, maintaining series resistance values closer to the average of the benchmark data. Although it does not surpass the minimum benchmark series resistance values, the CRL1206-JW-R100ELF substantially outperforms the maximum values.

However, as the test frequency increases, a few discrepancies between the CRL1206-JW-R100ELF's performance and the benchmark data begin to appear. Notably, in the 50 kHz to 1 MHz frequency range, the resistor's series resistance leans more towards the higher end of the statistical benchmark. Such a tendency could significantly impact efficiency and consistency in circuits operating at mounting frequencies and merits careful consideration.

Upon comparing the LCR measurements at 10 Volts, the performance landscape alters somewhat. Below 50 kHz test frequencies, the CRL1206-JW-R100ELF exhibits marginally higher series resistance values than those recorded at 1 Volt. Intriguingly, the resistor outshines the benchmark once the test frequency surpasses 50 kHz, displaying markedly lower series resistance values than the average. Its optimal performance lies between 75 kHz and 300 kHz, where it exhibits the most significant improvements.

In terms of resistance performance, the CRL1206-JW-R100ELF displays consistently favorable results compared to the benchmark thick film resistor data, especially in the lower test frequency ranges. Its exceptional performance at higher voltage test frequencies above 50 kHz makes it an ideal candidate for applications that prioritize lower series resistance values. Therefore, it is crucial to factor in these observations when considering the integration of the CRL1206-JW-R100ELF resistor into your circuits.

Inductance

When examining the inductance values at 1 Volt for the CRL1206-JW-R100ELF resistor, a comprehensive analysis reveals some noteworthy aspects. In comparison to the average inductance of other components in the benchmark, this resistor displays lower inductance across the measured test frequencies. Additionally, it is essential to understand that the inductance tends to be closer to the minimum values specified in the statistical benchmark, which corresponds to the trend observed in the lower end of the benchmark.

At higher voltages of 10 Volts, the available data set is somewhat limited, and hence a complete comparison cannot be provided. Nonetheless, we should emphasize the considerably increased inductance observed at 5Hz and 10Hz test frequencies, where the CRL1206-JW-R100ELF resistor demonstrates 85.66μ and 83.96μ inductance levels respectively. These values are markedly higher than the 1 Volt measurements, which indicates a non-linear response to voltage escalation at lower test frequencies.

Upon analyzing these observations in detail, it can be concluded that the CRL1206-JW-R100ELF resistor exhibits lower inductance values compared to the average inductance derived from the benchmark data. Thus, this component presents itself as a beneficial choice for applications that demand minimized inductance. However, it is crucial for engineers to meticulously evaluate the substantially increased inductance observed at lower test frequencies under elevated voltage conditions before deciding on the adoption of this component for their applications.

Comparative Analysis

With the test data provided, we can analyze the Bourns CRL1206-JW-R100ELF 100m thick film resistor's performance against the statistical benchmark data. Focusing on impedance, quality factor, series resistance, and series inductance at 1V and 10V, the findings provide an in-depth comparison to determine the suitability of this resistor for specific applications.

At 1V, the CRL1206-JW-R100ELF's impedance stays within the min and max impedance values for all test frequencies. It closely follows the average impedance trend of the benchmark, indicating consistency in performance. The quality factor is not available for lower frequencies; however, starting at 75kHz, it follows a trend comparable to the benchmark, showcasing satisfactory performance.

The CRL1206-JW-R100ELF series resistance stays within the benchmark's min and max values across all test frequencies. While the trend mostly aligns with the benchmark average, there are slight deviations at certain test frequencies.

For series inductance at 1V, the CRL1206-JW-R100ELF falls within the benchmark's min and max values for test frequencies up to 1M. The trend closely aligns with the benchmark's average, thus implying satisfactory performance.

At 10V, the resistor series resistance mostly stays within the benchmark data, except the outliers at 5k, 10k and 20k, which deviate from the benchmark values. The trends in quality factor and dissipation factor further strengthen the performance of this resistor at 10V. The series inductance data is not sufficient to come to a conclusion, as several test frequency measurements are missing, making it challenging to form a reliable comparative analysis.

In conclusion, the Bourns CRL1206-JW-R100ELF thick film resistor demonstrates a consistent performance compared to the statistical benchmark within the 1V range. However, the provided data for 10V measurements is not sufficient for a detailed comparative analysis in some aspects, making it crucial for engineers to evaluate their specific application requirements and consider additional data measurements if needed.
