The Ohmite part number 43FR10E resistor, constructed with a wirewound composition, may outperform its benchmark, making it a noteworthy component in the realm of electronic engineering.

Resistance

Starting with the resistance measurements at 1 Volt, we observe that the 43FR10E Resistor remains relatively within the statistical benchmark range, showcasing the component's reliability. With an average series resistance of 100 milliohms (mΩ) at 1kHz, it performs slightly better than the statistical benchmark's average of 91.83 milliohms. This trend continues as the test frequency increases, demonstrating the consistency and stability of Ohmite's component, which speaks to the quality of its design and fabrication processes.

Moreover, while examining the series resistance at 10 Volts, we notice comparable performance to the statistical benchmark supporting the earlier statements on the component's dependability. It is important to highlight that the 43FR10E Resistor surpasses performance expectations at lower test frequencies, ranging from 5Hz to 1kHz. For instance, when compared to the benchmark average of 92.1mΩ, the resistance at 50Hz is markedly lower at around 52.26mΩ, which indicates efficiency in certain application scenarios. However, we can observe a notable jump in resistance as the test frequency exceeds 20kHz, indicating areas where its performance may not be optimal.

The 43FR10E demonstrates a noteworthy profile across numerous frequency ranges, indicating a level of suitability and adaptability for different types of applications.

At lower frequencies, such as 5 Hz and 10 Hz, the inductance data for the 43FR10E were not available for comparison. Nonetheless, at 50 Hz, the component exhibits an inductance value of 303.1 nH, which is slightly below the average benchmark of 598.7 nH. This suggests that the 43FR10E is well-suited for use in low-frequency applications where a marginal reduction in inductance is desirable. By 100 Hz, the 43FR10E resistor's inductance drops to 37.24 nH, further emphasizing its competitive potential as it's notably below the benchmark average of 52.5 nH.

As we progress along the frequency spectrum, the inductance values of the 43FR10E wirewound resistor continue to demonstrate impressive performance by staying below or within close proximity to the respective benchmark averages. For example, at 500 Hz and 1 kHz, this resistor registers inductance levels of 47.42 nH and 16.91 nH, coming in lower than their corresponding benchmark averages of 35.69 nH and 8.074 nH, respectively. This performance trend is maintained as the frequencies increase to 5 kHz and 10 kHz, with the 43FR10E delivering inductance values of 30.91 nH and 26.38 nH, as opposed to benchmark averages of 12.34 nH and 7.925 nH, respectively.

Moreover, the 43FR10E shows remarkable consistency by maintaining its performance when evaluated across even higher frequencies. A prime example of this consistency can be observed at 50 kHz, where this resistor registers an inductance of 23.4 nH, only marginally above the benchmark average of 6.844 nH. This continued reliability across a broad frequency range accentuates the versatile attributes of the Ohmite 43FR10E wirewound resistor and validates its potential for use in various applications. To further support this assertion, the inductance values measured at 10 volts exhibit a similarly desirable profile, aligning well with the 1-volt measurements and encouraging confidence in the component's overall performance.

Comparative Analysis

The Ohmite 43FR10E Resistor is a Wirewound, throughHole item with an axial package, boasting a nominal value of 100m and a tolerance of ±1%. In this comparative analysis, we aim to evaluate the performance of the 43FR10E in the context of the provided statistical benchmark data.

Upon comprehensive examination at 1 Volt, the 43FR10E Resistor displays an imbalance in impedance results throughout the frequency range, diverging from the statistical benchmark averages. For instance, at lower frequencies such as 5, 10, and 50 Hz, the 43FR10E's impedance values are significantly higher at 100.1m, 100m, and 99.95m Ohms, respectively- considerably deviating from average values of 91.73m, 92m, and 92.1m Ohms. Notably, this trend carries on throughout the entire range of frequencies.

Meanwhile, when scrutinizing the Quality Factor presented in the 43FR10E data at 1 Volt, it consistently remains under 0.01 at all frequencies under 5kHz. Interestingly, as the frequencies elevate into the 5k-100kHz range, the Quality Factor approaches the statistical benchmark gradually, with the quality factor exceeding the maximum average value from 250 kHz and beyond.

In terms of Series Resistance, the values recorded for the 43FR10E differ slightly from the statistical benchmark averages. At 1k Hz, for example, the resistances are aligned at around 100m Ohms; whereas notable disparities arise within higher frequencies - for instance, at 50k Hz, these divergent values sit at 100.3m Ohms for the 43FR10E and 92.22m for the benchmark. Consequently, this indicates that the 43FR10E's Series Resistance is slightly higher when compared to the statistical benchmark throughout diverse frequency ranges.

Finally, the Series Inductance at 1 Volt entails noteworthy deviations when juxtaposed with the statistical benchmark. For example, at 1 kHz, the 43FR10E sits at 16.91n Henries, while the benchmark data aligns around 8.074n Henries; significant discrepancies are similarly apparent at 20 kHz, as the 43FR10E rests at 24.59n Henries in comparison to the 7.383n benchmark. As such, the 43FR10E consistently tilts towards higher inductance values across the frequency spectrum.

In conclusion, the Ohmite 43FR10E Resistor's performance - when assessed against the provided statistical benchmark - illustrates disparities in key categories, such as Impedance, Quality Factor, Series Resistance, and Series Inductance. Engineers evaluating the 43FR10E for integration in their circuits should carefully consider these performance aspects, comparing them to the part number-based statistical benchmarks and analyzing alignment with their specific design requirements.

Conclusion

In this technical review, we have analysed the performance of the Ohmite 43FR10E Resistor by comparing its LCR measurements with the statistical benchmark data. The Ohmite 43FR10E Resistor has shown a mixed performance in contrast to the statistical benchmark data.

At lower test frequencies, particularly below 5 kHz, the 43FR10E tends to have a higher impedance and series resistance compared to the benchmark. However, at higher test frequencies, it performs relatively better in terms of impedance, consistently showing lower values compared to the benchmark average. Additionally, in the 10 Volts LCR measurements, it's noticeable that the quality factor and dissipation factor vary significantly across the different test frequencies.

When comparing the series inductance values, a similar trend appears. The 43FR10E has lower inductance values at higher test frequencies, which could impact certain applications where precise inductance control is required. On the other hand, at lower test frequencies, this Resistor tends to have slightly higher inductance values.

As an engineer exploring whether this Resistor is an optimal choice, it is essential to weigh the specific application requirements against the performance characteristics of the Ohmite 43FR10E Resistor. In general, applications that require lower impedance and inductance values at higher test frequencies and can handle slight variations in these values might benefit from this component. However, for applications where precise control over impedance, resistance, and inductance values is required, especially at lower frequencies, one may need to look for other options that provide better performance consistency.
