Impedance

In this section, we will analyze the impedance performance of Ohmite's KDV08FR100ET Resistor by comparing it to the provided statistical benchmark data. Impedance is a crucial parameter in electronic applications, as it directly impacts the overall circuit performance and efficiency.

Upon examining the LCR measurements of the KDV08FR100ET at 1 Volt, it demonstrates a consistent performance compared to the statistical benchmark's average impedance values. At a low frequency of 5 Hz, the impedance of the resistor is measured at 91.69m Ohms, closely resembling the benchmark's average impedance of 91.73m Ohms. This trend continues across the entire frequency range, maintaining a difference of less than ±1.2m Ohms from the benchmark average up to 1 MHz. This consistency confirms the reliability and dependable performance of this metal film resistor in terms of impedance within the testing voltage of 1 Volt.

However, when analyzing the KDV08FR100ET's LCR measurements at a higher testing voltage of 10 Volts, an abrupt change in impedance is observed at 20 kHz. At this frequency, the impedance significantly surpasses the statistical benchmark values, reaching a peak value of 105.1m Ohms. Following this peak, the impedance drops to 83.04m Ohms at 50k. This deviation raises concerns about the stability and reliability of the resistor's performance in higher voltage environments.

While the KDV08FR100ET Resistor demonstrates a highly consistent and reliable impedance performance in a 1 Volt testing environment, closely matching the statistical benchmark data, it is important for potential users to exercise caution in higher voltage applications. Thorough testing under specific application conditions is recommended to ensure the resistor's suitability for the desired application. The suitability of this resistor will ultimately depend on the voltage and frequency requirements of the specific electronic application in which it will be utilized.

Resistance

In this section, we will be evaluating and comparing the performance of Ohmite's KDV08FR100ET 100m Ohm Metal Film Resistor against statistical benchmarks derived from other competing components with the same value. The focus will be on assessing the series resistance at two test voltages, 1 Volt and 10 Volts, across a range of test frequencies, from 5 Hz to 1 MHz.

When tested at a voltage of 1 Volt, the KDV08FR100ET exhibits a fairly consistent series resistance ranging from 91.67m to 92.01m Ohms across the tested frequency range. Comparing this performance with the benchmark data, which demonstrates an average series resistance ranging from 91.71m to 93.43m Ohms, it is evident that the KDV08FR100ET performs competitively. Its values consistently fall within or close to the average benchmark range, reflecting a high degree of reliability. Additionally, the relatively small variations between max and min observed in the benchmark data indicate a high level of consistency in the manufacturing process. Furthermore, it should be noted that the KDV08FR100ET adheres to the ±1% tolerance specification of the product, performing well within the desired confidence interval.

At a higher test voltage of 10 Volts, however, a different profile emerges. In this case, the KDV08FR100ET demonstrates wider variations in its series resistance, ranging from 79.71m to 97.67m Ohms across different test frequencies. Within the lower frequency range (5 Hz to 20 kHz), the resistor exhibits a higher resistance compared to its counterparts in the benchmark data. Conversely, between 50 kHz and 300 kHz, the KDV08FR100ET exhibits significantly lower series resistance when compared to the average benchmark series resistance, with only a few exceptions. Beyond 300 kHz, the resistor's performance realigns more closely with the benchmark data, suggesting better consistency at higher frequencies.

In conclusion, the KDV08FR100ET metal film resistor performs competitively against the statistical benchmark data when tested at 1 Volt, demonstrating consistency and adherence to tolerance specifications. However, its performance exhibits more significant variations in series resistance when tested at 10 Volts. Engineers should carefully consider these variations when evaluating the suitability of this resistor for their circuits, particularly when operating at higher voltage levels, as these differences could impact circuit performance depending on the specific use case scenario.

Inductance

The inductance measurements of the Ohmite KDV08FR100ET inductor were thoroughly examined at a test voltage of 1 Volt and compared against the industry-standard statistical benchmark. It is important to understand that inductance varies across different frequencies; therefore, we have analyzed the performance of this component at multiple frequencies ranging from as low as 5 Hz to as high as 1 MHz to give a comprehensive insight into its performance.

At lower test frequencies such as 5 Hz and 10 Hz, the Ohmite KDV08FR100ET exhibits higher inductance values of 2.711μH and 685.5nH, respectively, compared to the average benchmark values of 3.411μH and 868.9nH. This indicates that the inductor exhibits lower inductance performance at very low frequencies, which may cause challenges with filtering and energy storage in specific applications like power supply filters that operate at these frequencies.

Significantly, as the test frequency is increased to 50 Hz, the inductance measurement for the Ohmite KDV08FR100ET narrows down to 561.1nH, which is much closer to the benchmark average of 598.7nH. This performance continues to remain proximate to the benchmark average as the test frequency reaches up to 500 kHz, with the highest discrepancy observed at 100 kHz. There, the measured inductance value is 1.539nH against the average value of 6.597nH for the benchmark. Such deviation may affect the behavior of frequency-dependent circuits or systems where the response needs to be highly precise.

In contrast, from 250 kHz to 1 MHz, the Ohmite KDV08FR100ET starts to exhibit slightly higher inductance values compared to the benchmark average. This could affect its performance in high-frequency applications, such as radiofrequency electronic circuits or high-speed digital signal processing, where precise inductance values are critical. Nonetheless, the overall inductance performance of the Ohmite KDV08FR100ET falls relatively close to the statistical benchmark for the tested frequencies. This characteristic makes it a viable candidate for various circuits and applications that do not rely heavily on superlative inductance precision.

Comparative Analysis

The Ohmite KDV08FR100ET is a Metal Film Resistor with a nominal value of 100m, a tolerance of ±1%, and a surface mount package (0805). We will analyze its performance compared to the statistical benchmark that was formed from other components of the same value. In this comparative analysis, we will compare data from LCR measurements at 1V and 10V against benchmark data.

Overall, the KDV08FR100ET performs close to the benchmark, with consistent impedance values across frequencies. When observing impedance values at lower frequencies (5, 10, 50Hz), the resistor performs slightly worse than the average benchmark values. However, the deviation is not significant and is within the tolerance range.

Furthermore, the KDV08FR100ET presents marginally lower average series resistance values across various frequencies. This resistor also performs consistently in terms of series inductance, with only slight deviations from the statistical benchmark. It is worth noting that the KDV08FR100ET presents a small quality factor in a limited frequency range (100k to 300k). However, this factor is still low and comparable to the statistical benchmark.

Comparing the LCR measurements at 10V, similar trends can be observed. The KDV08FR100ET exhibits stable impedance values that slightly deviate from the benchmark in lower frequencies but aligns better with statistical averages as the frequencies increase. Moreover, the Ohmite resistor maintains reasonable dissipation factor and quality factor values across frequencies, with only minor deviations from benchmark data.

To summarize, the Ohmite KDV08FR100ET metal film resistor demonstrates relatively satisfactory performance when compared to the statistical benchmark. Given its consistency and low deviations, engineers can consider this resistor a suitable choice for applications requiring a 100m metal film resistor within the provided 1% tolerance.

Conclusion

In comparison to the statistical benchmark, the Ohmite KDV08FR100ET Metal Film resistor delivers mixed performance results. While it demonstrates excellent stability at low test frequencies, it is outperformed by competitors at higher frequencies in terms of impedance and series resistance.

At 5 kHz and below, this resistor matches or exceeds the benchmark averages for Impedance and Quality Factor. However, its performance starts to deviate from the benchmark when the test frequency is raised above 20 kHz, with the impedance and series resistance straying from those observed in the benchmark at similar frequencies.

Additionally, at low test voltages (1V), the KDV08FR100ET exhibits excellent performance for quality factor, even surpassing the benchmark at some frequencies. Yet, when the voltage increases to 10V, the quality factor declines, losing the advantage observed at 1V in selected frequency bands.

In summary, the Ohmite KDV08FR100ET may be a suitable resistor for low-frequency applications or those where stability at low operating voltages is a priority. However, engineers considering this component for high-frequency or high-voltage circuits may need to evaluate other options. While the KDE08FR100ET offers some benefits, further investigation into alternative resistors that excel at higher frequencies or voltages may yield better results for more demanding applications.
