For the review of Ohmite's KDV12FR100ET Resistor, we will be taking into account the LCR measurements that cover a wide range of test frequencies at 1 Volt and 10 Volt input values. In the sections to follow, we will dive deeper into the analysis of these measurements and provide a comprehensive understanding of how well the KDV12FR100ET performs in comparison to the benchmark data.

Impedance

This section of the review provides a comprehensive analysis of the impedance performance of the Ohmite KDV12FR100ET 100m Metal Film Resistor, in comparison to the given statistical benchmark data of other similar components. The evaluation will be conducted under two different voltage conditions, 1 Volt and 10 Volts, to present a more complete picture of its impedance capabilities.

When examined at 1 Volt, the KDV12FR100ET Resistor demonstrates a higher impedance than the average impedance taken from the benchmark dataset for every test frequency. In certain instances, the value approaches the upper limit of the maximum impedance observed in the statistical dataset. To be specific, at a test frequency of 5 Hz, the KDV12FR100ET shows an impedance of 80.89m Ohm, while the average value from the benchmark is 91.73m Ohm. As the test frequency increases, the difference between the observed values and the benchmarks remains consistent across the entire frequency range, right up to a 1M test frequency (83.40m Ohm in KDV12FR100ET as opposed to an average of 108.30m Ohm).

Upon examining the 10 Volts test, the KDV12FR100ET Resistor exhibits a considerable variance in its impedance performance. At certain test frequencies, particularly those above 20 kHz, the resistor's impedance deviates significantly from the benchmark values. For instance, at 50 kHz, the impedance measures 73.32m Ohm in comparison to the benchmark's average impedance of 92.22m Ohm.

Engineers seeking to determine whether this Resistor would be an optimal choice for their applications must pay close attention to the impedance values when considering the KDV12FR100ET Resistor. While the observed impedance for most test conditions is higher than the benchmark's average impedance, there are notable discrepancies at specific test frequencies during the 10 Volts test, especially at higher frequencies. These inconsistencies may warrant further consideration depending on the precise requirements and parameters of the desired application.

Resistance

Ohmite's KDV12FR100ET resistor is a metal film resistor with a nominal value of 100 milliohms (100mΩ), characterized by a tight tolerance of ±1%. Metal film resistors are known for their stable performance and relatively low temperature coefficients, making them suitable for a wide range of applications.

Upon an analytical comparison with the established statistical benchmark at 1 Volt and taking into consideration the LCR measurements gathered for the KDV12FR100ET resistor, it becomes apparent that the component exhibits a reasonably consistent performance. It is indeed worth noting that the series resistance seems to be higher than the average benchmark resistance across the majority of the test frequencies examined.

As we contrast the results with those obtained at 10 Volts, interesting insights about this particular resistor emerge. In the lower test frequency range - up to 200 kHz - the metal film resistor's performance falls within the anticipated parameters. This highlights the component's reliable behavior in applications operating in the low to medium frequency range.

However, as test frequencies increase, the series resistance response tends to fluctuate more significantly, suggesting that the resistor might not be as reliable in specific high-frequency applications. This observation highlights the importance of carefully considering the specific operating frequency range when selecting a resistor to avoid potential performance limitations or inconsistencies.

Overall, the Ohmite KDV12FR100ET resistor exhibits a relatively stable and consistent performance in the low to medium frequency range with an accuracy of ±1%. However, when utilized in high-frequency applications, more significant fluctuations in the series resistance response are observed, warranting careful scrutiny when selecting a resistor for such purposes.

Inductance

In this section, we will deeply analyze the inductance performance of Ohmite's KDV12FR100ET Metal Film Resistor and compare it to a statistical benchmark established for components with the same nominal value. This comparison will cover measurements recorded at two different voltage levels: 1 Volt and, where available, at 10 Volts. By conducting this thorough analysis, we aim to provide comprehensive insights into the suitability of this particular resistor in different inductance applications.

At a voltage of 1 Volt, the KDV12FR100ET Resistor demonstrates lower inductance values at test frequencies up to 10 kHz, with the exception of 50 kHz. For instance, at a test frequency of 5 kHz, the measured inductance is 7.154 nH, significantly lower than the benchmark's average of 12.34 nH for the same frequency. In higher test frequencies, the KDV12FR100ET displays comparable inductance levels to the statistical benchmark, with small variations observed in specific cases such as at 450 kHz and 550 kHz. At these frequencies, the resistor outperforms the benchmark with inductance values of 1.961 nH and 1.964 nH, respectively.

Regarding the 10 Volt LCR measurements, the available data for comparison is restricted. Nevertheless, some critical observations can be made to deduce the resistor’s performance at this voltage level. At a test frequency of 5 Hz, the KDV12FR100ET exhibits an inductance of 86.94 μH, which is considerably higher than the statistical benchmark's 5 Hz average of 3.411 μH. Furthermore, at 100 kHz, the resistor displays an inductance of 278 nH, placing this value between the benchmark's minimum (101.2 nH) and maximum (1.007 μH) at the same frequency.

Taking into account these in-depth findings, it becomes evident that the KDV12FR100ET Metal Film Resistor offers acceptable performance, particularly in specific inductance applications where higher frequencies are involved. Engineers evaluating this component for implementation in their circuits may consider it a viable choice when lower inductance values are desired or required for high-frequency operations. This comprehensive analysis aids in understanding the performance characteristics of the KDV12FR100ET Metal Film Resistor, allowing for a more informed decision when selecting components for electronic circuits and systems.

Comparative Analysis

In this analysis, we will evaluate the performance of Ohmite KDV12FR100ET, a Metal Film Resistor with a nominal value of 100m, tolerance of ±1%, surface mount capability, and 1206 (3216 Metric) package size. We will compare its impedance, series resistance, inductance, and capacitance parameters to the statistical benchmark data provided. This will aid electronics engineers in determining if this Metal Film Resistor exhibits suitable performance for their circuit applications.

Starting with the impedance at 1 Volt, we observe that the KDV12FR100ET produces a higher resistance as compared to the statistical benchmark average. For example, at 5Hz, the sample component data presents an impedance of 80.89m, which is comparatively higher than the benchmark average impedance of 91.73m. Similarly, at higher frequency bands (e.g. 100kHz), the KDV12FR100ET still shows higher impedance values (82.08m) relative to the benchmark average (92.53m).

Moving on to the series resistance, it is noticeable that the KDV12FR100ET performs with higher series resistance values as opposed to the benchmark averages across various test frequencies. For instance, at 100kHz, the KDV12FR100ET presents a series resistance value of 82.08m while the benchmark average series resistance rests around 92.07m.

As for series inductance, we observed that the KDV12FR100ET shows larger inductance values compared to the benchmark. At 1kHz, the KDV12FR100ET possesses an inductance of 6.151n, which is more than the benchmark average inductance of 3.411μ. Series capacitance analysis reveals that the KDV12FR100ET performs with lower capacitance values. For example, at 1kHz, it produces a capacitance value of 3.807 compared to a significantly higher benchmark average (6.001).

Lastly, the 10 Volts LCR measurements exhibit a stable performance of the KDV12FR100ET across most test frequencies. For example, at 100kHz, the series resistance remains constant around 70.95m within the given input voltage range.

In conclusion, the KDV12FR100ET Metal Film Resistor from Ohmite exhibits variable performance in relation to the benchmark data. Notably, it demonstrates a relatively heightened impedance, series resistance, and inductance values, while showing lower values for series capacitance. Therefore, electronics engineers should carefully consider these observations while assessing the applicability of this Metal Film Resistor for their specific circuit requirements.

Conclusion

In summary, Ohmite's KDV12FR100ET metal film resistor's performance was compared to the statistical benchmark collected from other components of the same value. The KDV12FR100ET exhibits a slightly higher impedance and series resistance than the benchmark data at 1 Volt. While it does show a marginally better Q-factor performance, it should be noted that the deviation is minimal.

However, at 10 Volts, the KDV12FR100ET falls short of the benchmark performances in terms of impedance, series resistance, and the dissipation factor. Considering these findings, engineers should be cautious when deciding to use this resistor in their circuit designs, as other components on the market may prove to be better suited for certain applications and requirements.

Overall, the Ohmite KDV12FR100ET metal film resistor does not stand out as a top-performing component when judged against the statistical benchmark. Depending on the specific application and requirements, it may be worthwhile for electronics engineers to further evaluate other resistors in this category for optimum performance and reliability.
