Impedance

Upon analyzing the Bourns Inc. CRM0805-JX-R100ELF Resistor's impedance performance and comparing it to the established statistical benchmark at 1 Volt, the data shows that this particular component deviates from the average impedance range exhibited by resistors with the same nominal value. Specifically, the Bourns CRM0805-JX-R100ELF Resistor tends to demonstrate higher impedance values consistently across various test frequencies.

For example, when tested at a 5Hz frequency, the CRM0805-JX-R100ELF Resistor measures an impedance value of 84.82m Ohms, which falls outside the established benchmark range of 76.51m to 104.7m Ohms. A similar discrepancy can be seen at 50kHz test frequency, where the component has an impedance value of 85.76m Ohms compared to the benchmark range of 77.62m to 104.5m Ohms. These disparities between the CRM0805-JX-R100ELF Resistor and the statistical benchmark persist as the test frequency increases.

Investigating further with the LCR measurements at 10 Volts, the component's impedance performance varies from the 1 Volt data but still positions itself outside the defined benchmark range. For instance, at 20kHz, the CRM0805-JX-R100ELF Resistor measures an impedance value of 94.35m Ohms, which surpasses the 1 Volt benchmark maximum of 92.07m Ohms. It is important to note that there are some data points unavailable for higher test frequencies, resulting in gaps in the performance analysis at 10 Volts.

When considering the Bourns Inc. CRM0805-JX-R100ELF Resistor for integration into their products, engineers ought to pay close attention to the consistently higher impedance values observed in comparison to the statistical benchmark. This deviation in performance could imply that the Thick Film Resistor may not be an ideal selection for applications that require impedance values more closely aligned with established benchmarks.

Resistance

In evaluating the performance of Bourns Inc.'s CRM0805-JX-R100ELF Resistor, a detailed analysis was carried out by comparing the component's resistance measurements with the provided benchmark data. This assessment involved obtaining resistance profiles of the resistor under test at various frequencies with an input voltage of 1 Volt.

For the 1 Volt input measurements, the CRM0805-JX-R100ELF Resistor exhibited a range of series resistance values, starting at 84.79m Ohms at a test frequency of 5 Hz and peaking at 85.8m Ohms for 75 kHz. It is important to note that these values exhibit a fairly consistent pattern with the statistical benchmark averages, although with a small upward deviation. Interestingly, the CRM0805-JX-R100ELF outperformed the benchmark at certain frequencies such as 75k, 100k, 150k, and 250k, displaying lower resistance values compared to the average figures of the benchmark. Conversely, at test frequencies of 5k, 10k, 20k, and 50k, the CRM0805-JX-R100ELF demonstrated higher resistance values than the benchmark.

At 10 Volt input measurements, a similar trend was observed. However, it should be noted that the available test data is incomplete for frequencies above 750 kHz at 10 Volts input. Despite the available data's limitations, the CRM0805-JX-R100ELF Resistor consistently exhibited slightly higher resistance values throughout most of the observed frequencies, compared to the statistical benchmark average. Comprehensive data for all relevant test frequencies is essential to carry out a more accurate evaluation of the resistor's performance in this respect.

In conclusion, Bourns Inc.'s CRM0805-JX-R100ELF Resistor demonstrates a performance that is closely aligned with the presented industry benchmark data. The resistor showcases lower resistance values at several test frequencies, outperforming the benchmark, while recording marginally higher resistance values in a few other critical frequencies. Thus, the CRM0805-JX-R100ELF proves to offer suitable resistance performance characteristics that adhere to the industry benchmarks, making it a reliable component for electronic circuitry.

Inductance

The Bourns Inc. CRM0805-JX-R100ELF exhibits a range of inductance values, which vary with the test frequency when measured at 1 Volt. It generally falls within the average inductance ranges of similar components, although there are some deviations worth noting. The inductance values shift in correspondence to the test frequency, reflecting a common characteristic of inductive components.

At a test frequency of 5 Hz, it measures at 2.924μH, which is closer to the benchmark maximum series inductance of 5.906μH than the average value of 3.411μH. However, it still remains within acceptable boundaries. As the test frequency increases, the inductance value tends to approach the benchmark average, with some fluctuations. At 10kHz, the component reported a series inductance of 1.709nH, which is close to the average value of 7.925nH. At higher frequencies, such as 450kHz, the inductance lies closer to the benchmark average and maximum—1.627nH compared to the 6.284nH average and 35.57nH maximum.

When measured at a higher voltage of 10 Volts, the inductance values for the CRM0805-JX-R100ELF exhibit a similar trend, with most measurements closer to the benchmark average, but they demonstrate wider deviations. For example, at a test frequency of 5 Hz, the inductance value measures at 88.58μH, considerably higher than the statistical benchmark data. The value, however, decreases substantially with increasing frequency, aligning closer to the benchmark average values. At 100kHz, the component reported a series inductance of 1.56nH, demonstrating an acceptable deviation from the 6.597nH average provided by the benchmark data.

Overall, the inductance performance of the CRM0805-JX-R100ELF generally aligns with the range of the statistical benchmark values. Some values deviate further from the average, particularly at lower frequencies, although these deviations become less pronounced as the test frequency increases. This insight implies that the component is likely suitable for use in most electronic circuits, where inductance values within this range are acceptable, bearing in mind such behavior is influenced by the surrounding electronic components and test conditions.

Comparative Analysis

In this comparative analysis of the Bourns Inc. CRM0805-JX-R100ELF Resistor, we will be assessing its performance against a statistical benchmark formed from other 100m resistors. The surface-mounted thick film resistor offers a ±5% tolerance in an 0805 (2012 Metric) package.

At 1 volt, the CRM0805-JX-R100ELF Resistor exhibits an impedance ranging from 84.82m Ohms to 86.14m Ohms whereas the statistical benchmark varies from 76.51m Ohms to 93.94m Ohms. The Bourns Resistor exhibits a narrower range of impedance values, demonstrating consistent performance when compared to the broader benchmark range.

When analyzing the Resistor's series resistance, its performance covers a range of 84.79m Ohms to 85.6m Ohms, while the benchmark spans 76.49m Ohms to 93.39m Ohms, showing the component's superior consistency in comparison to the benchmark.

In terms of the test frequency, the CRM0805-JX-R100ELF Resistor exhibits a narrower range of inductance values, spanning from 1.578n Henries to 2.924μ Henries. On the other hand, the benchmark extends from 1.638μ Henries to 5.906μ Henries, highlighting the improved resilience of the Bourns Resistor concerning inductance shifts with varying frequencies.

However, the CRM0805-JX-R100ELF Resistor lacks quality factor data for most of the tested frequencies at 1 Volt, while the benchmark section does provide these data points. Quality factor data are essential for determining the efficiency of the Resistor in minimal energy dissipation.

At 10 volts, the CRM0805-JX-R100ELF Resistor exhibits similar impedance trends with a range of 73.87m Ohms to 94.35m Ohms. In comparison, the statistical benchmark stays within 76.16m Ohms to 116.3m Ohms. Again, the Bourns Resistor demonstrates greater consistency in impedance values when compared to the benchmark.

Although the Bourns Resistor does show improved overall consistency compared to the statistical benchmark, the lack of quality factor data at various test frequencies is an area of concern. As such, further performance evaluations may be necessary to make a more comprehensive assessment of its applicability and overall efficiency in specific product designs.

Conclusion

In assessing the performance of the Bourns CRM0805-JX-R100ELF Thick Film Resistor, it was compared to the statistical benchmark measurements at 1 Volt. The comparison revealed mixed results but showcased the overall performance of this surface-mount resistor.

At lower test frequencies, the CRM0805-JX-R100ELF demonstrated higher impedance and series resistance values compared to the benchmark average values. However, it also exhibited better performance in terms of series inductance, with lower values on most occasions.

At higher test frequencies - ranging from 100 kHz to 1 MHz, the component maintained lower series inductance values, signifying its suitability for applications requiring minimal inductive peaking and high-frequency filtering. Conversely, the quality factor values at these frequencies tend to be lower than the benchmark average, indicating higher amounts of energy lost to parasitic elements.

In conclusion, the Bourns CRM0805-JX-R100ELF Thick Film Resistor is well-suited for certain applications where lower inductive characteristics are required. Electronics engineers seeking a resistor for high-frequency filtering can consider this component, bearing in mind its slightly higher impedance and series resistance values alongside its lower quality factor values compared to the statistical benchmark.
