Impedance

The Ohmite 15FR100E, with a nominal impedance value of 100 milliohms (mΩ) and a tolerance of ±1%, is evaluated against statistical benchmark data to assess its impedance performance. In this comparison, impedance measurements at 1 Volt and 10 Volts across a range of test frequencies are presented to provide an in-depth analysis of the component's performance characteristics.

At 1 Volt, the 15FR100E exhibits an average impedance value of approximately 99.79 mΩ. This value is notably higher than the benchmark's average value (92 mΩ) across the same test frequencies. The range between the minimum and maximum recorded impedances for the 15FR100E component at 1 Volt is considerably smaller than the range exhibited by the benchmark data. This difference is particularly noteworthy at test frequencies between 5 kHz and 1 MHz, where the 15FR100E exhibits a diminishing difference between its impedance value and the benchmark maximum value. The smaller range indicates better stability and consistency compared to the benchmark's performance.

At 10 Volts, impedance measurements for the 15FR100E beyond 700 kHz are not available, limiting the comparison for these higher frequency data points. Nonetheless, at test frequencies between 5 kHz and 600 kHz, the 15FR100E exhibits a steady decrease in impedance levels when compared to the benchmark data. At frequencies between 20 kHz and 50 kHz, the component demonstrates impedance values exceeding the benchmark average of 92.07 mΩ and 92.22 mΩ, respectively. This suggests potential areas of concern with regard to performance under high-amplitude conditions.

In conclusion, the 15FR100E exhibits impedance values above the statistical benchmark averages across most test frequencies, with varying degrees of difference observed relative to minimum and maximum recorded benchmark values. Despite signs of performance decline at specific test frequencies at 10 Volts, the 15FR100E maintains an overall stable performance characteristic. This thorough analysis not only provides a comprehensive assessment of the component's impedance performance, but also offers insights that could help improve understanding of its behavior under various conditions.

Equipped with a tolerance level of ±1%, this component exhibits remarkable stability and consistency across a wide range of test frequencies at both 1V and 10V test conditions. As such, it offers reliability and precision for various electronic applications.

At 1V test conditions, the 15FR100E Resistor displays relatively higher series resistance values than the average benchmark values. For instance, at a test frequency of 50 kHz, the component's series resistance measures 99.67mΩ, whereas the benchmark average stands significantly lower at 92.15mΩ. This trend can be observed at other test frequencies as well, such as 100 kHz and 200 kHz, where the component's series resistance values (99.83mΩ and 100mΩ) remain higher than the benchmark averages (92.28mΩ and 92.47mΩ). Of note, at higher test frequencies (500 kHz and above), the 15FR100E Resistor registers even larger deviations from the benchmark averages, showcasing a more pronounced gap between the recorded values and the average benchmark values.

On the other hand, at 10V test conditions, the Ohmite 15FR100E Resistor displays comparatively lower resistance values in contrast to the benchmark average. For instance, with a measured series resistance of 72.49mΩ at 50 kHz as opposed to the average benchmark value of 90.6mΩ, the component indicates a noteworthy difference. This deviation can be seen in other test frequencies as well, such as 100 kHz and 200 kHz, where the resistor's performance is significantly dissimilar to the statistical benchmark averages (88.64mΩ and 89.08mΩ).

In essence, the Ohmite 15FR100E Resistor's performance under different test conditions demonstrates its unique characteristics as a component. Understanding these variances in performance at various test frequencies and voltage levels is essential for engineers and designers when deciding to utilize this component in any particular electronic application, ensuring they account for any potential impact on the stability or efficiency of the system.

Inductance

The Ohmite 15FR100E exhibits varying inductance characteristics across an extensive range of test frequencies under both 1 Volt and 10 Volts conditions, providing an insightful assessment of the inductance performance behavior of this component.

At a low test frequency of 5 Hz, the measured series inductance value of 5.906µH at 1 Volt approaches the maximum benchmark value, indicating the potential need for additional inductance mitigation strategies in low-frequency applications. On the other hand, the inductance results at a 10 Volts test condition display a significant deviation - the values of 77.69µH and 81.76µH at 5 Hz and 10 Hz, respectively, reinforce the necessity of taking extra precaution in low-frequency circuit designs.

Moving towards higher test frequencies, the performance of the Ohmite 15FR100E becomes more consistent with the benchmark values. At 50 Hz and 1 Volt test condition, the recorded inductance of 610.8nH is within the average range (598.7nH) as specified by the benchmark data. Nevertheless, the component's performance in the 10 kHz to 100 kHz range requires improvement, as the inductance measurements under 1 Volt, ranging from 28.07nH to 28.35nH, fall short compared to the benchmark's maximum values of 37.65nH at 20 kHz and 35.92nH at 100 kHz.

In the upper frequency range, between 150 kHz and 1 MHz, the Ohmite 15FR100E demonstrates superior performance. The inductance values consistently hover around 28nH under 1 Volt, surpassing the average benchmark values and remaining in close proximity to them. This signifies that this component is highly suitable for applications requiring stable inductance in the high-frequency domain.

However, in the 10 Volts condition, the obtained inductance measurements within the frequency range of 250 kHz to 600 kHz still require enhancements to better align with the average benchmark values. Overall, it is crucial to consider these inductance performance variations when selecting and implementing the Ohmite 15FR100E in specific circuit applications.
