To dive deeper into the Resistor's impedance performance, we analyzed the Resistor at differing voltage levels, including 1 Volt and 10 Volts.

Upon testing at 1 Volt, the Resistor's impedance performance ranged from 92.71m Ohms at a low frequency of 5 Hz, and it eventually reached its peak value of 100.9m Ohms at a high frequency of 1 MHz. In each case, the test results remained within the range of the benchmark average values, indicating the Resistor's reliable performance. The maximum difference observed between the Resistor's performance and the benchmark data was at 4.90m Ohms when tested at 450 kHz, which equates to a relatively small deviation of 5.2% from the average value.

Moving on to the 10 Volts test, the LVM25FVR100E-TR Resistor demonstrated similar, consistent performance in terms of impedance values. The analysis displayed a minimum impedance of 81.66m Ohms at an intermediate frequency of 150 kHz, while it peaked at 99.86m Ohms upon reaching the higher frequency of 900 kHz. These findings further reinforce the Resistor's dependable traits, as the impedance measurements were within the range of the benchmark average values. The observed performance supports the Resistor's stability and robustness, ensuring that it can perform tasks as intended across various real-world scenarios.

In conclusion, the LVM25FVR100E-TR Resistor exhibits excellent impedance performance over a wide range of test frequencies and voltages, consistently staying within the benchmark data's specified tolerance range. This consistency adds to the Resistor's overall reliability, making it an appealing choice for applications that require a dependable and versatile component.

Resistance

In this in-depth analysis, we will study the resistance performance of the Ohmite LVM25FVR100E-TR metal foil resistor under two different voltage conditions: 1 Volt and 10 Volts. The review considers a wide frequency range, starting from 5 Hz and extending up to 1 MHz, providing a comprehensive understanding of the resistor's behavior across this spectrum.

At the 1 Volt testing range, the LVM25FVR100E-TR exhibits resistances that are quite similar to the benchmark dataset, particularly when tested at lower frequencies such as 5 Hz, where the measured resistance is 92.69m Ohms. Throughout the majority of the frequency range tested at 1 Volt, the device maintains a stable and consistent performance. Its measured resistances generally hover around the 92-93m Ohms mark, staying within the boundaries of the benchmark spread.

However, under the more challenging 10 Volts test condition, the LVM25FVR100E-TR showcases a more substantial reduction in series resistance in comparison to the benchmark data, particularly in the 50 Hz to 200 kHz range. For instance, at 50 kHz, the measured resistance dips to 84.26m Ohms, which is notably below the 92.15m Ohm provided by the benchmark average. This trend continues to be prominent in the results as the tested frequency is increased from 75 kHz onwards.

In conclusion, the Ohmite LVM25FVR100E-TR metal foil resistor demonstrates stable and reliable performance at the 1 Volt test conditions, with resistance values that are well aligned with the benchmark data. However, a distinct deviation from the benchmark is observed at the 10 Volt test level, particularly at higher frequencies, where the device consistently exhibits lower resistance values. Such behavior may be desirable or undesirable, depending on the specific design requirements and the context of the application. Engineers should carefully assess these findings and take them into consideration when determining the suitability of the LVM25FVR100E-TR resistor for their projects.

Inductance

In this section, we will assess the inductance performance of Ohmite's LVM25FVR100E-TR by comparing its series inductance characteristics to the statistical benchmark data of components with the same value. Our evaluation will provide insights into how this component performs within various test frequencies at different voltage levels.

When comparing the LVM25FVR100E-TR to the statistical benchmark values at 1 V, we notice that the component's series inductance is higher than the average values across most of the test frequencies. For instance, at a frequency of 5 Hz, the component measured 4.34μH, while the benchmark showed an average of 3.411μH. A similar discrepancy is observed at a frequency of 10 Hz, where the LVM25FVR100E-TR recorded 1.118μH compared to the benchmark average of 868.9nH, and at 50 Hz, the component measured 319.4nH, while the benchmark average was 598.7nH.

Despite these deviations, the LVM25FVR100E-TR maintains lower levels of inductance than the maximum values across most of the test frequencies at a voltage level of 1 V. This indicates a better overall performance within the general benchmarks for series inductance when compared to components with similar inductance values.

At a higher voltage level of 10 V, the LVM25FVR100E-TR showcases some significant deviations from the benchmark data. For some test frequencies, such as 5 Hz (93.15μH), 10 Hz (86.1μH), and 50 Hz (9.032μH), the component's inductance is notably higher than the statistical benchmark values. In contrast, it demonstrates considerably lower inductance at other test frequency levels, such as 75 kHz (625.6pH) and 100 kHz (3.569nH). These disparities imply that there could be room for improvement in terms of inductance performance within specific frequency ranges for the LVM25FVR100E-TR component.

To further optimize the inductance performance of this component, it is essential to understand the underlying factors that contribute to these variations within different frequency ranges. Engineering adjustments that target these specific frequency ranges may lead to improved consistency and reliability in the component's inductance characteristics, which is crucial for various electronic applications.

Comparative Analysis

This analysis involves Ohmite's metal foil resistor, part number LVM25FVR100E-TR, a 100mΩ resistor with a ±1% tolerance. In this review, the resistor's performance is compared to statistical benchmark data that represents other components with the same value. The intent is to provide an impartial comparison to help engineers determine if this resistor is an optimal choice for their applications.

Starting with the 1V measurements, the LVM25FVR100E-TR showed small deviations from the given statistical benchmarks at different test frequencies. Notably, at 50kHz, 75kHz, and 100kHz test frequencies, the series resistance was higher than the benchmark's average values. In addition, when we compared the quality factor values, the resistor exhibited a slightly higher quality factor of 0.02, which is on par with the max statistical benchmark value at 50kHz.

Moving to the 10V measurements, the LVM25FVR100E-TR resistor presented a series resistance that deviated more from the benchmark values at higher 20kHz, 300kHz, 400kHz, and 600kHz test frequencies. Moreover, the quality factor values were higher at 10kHz and 20kHz, but they remained within acceptable limits. Interestingly, the series capacitance at 500kHz showed an impressive difference in the statistical benchmark performance, but beyond 600kHz, the information was incomplete or unavailable for a comparison.

In conclusion, the Ohmite LVM25FVR100E-TR resistor performs comparably to the statistical benchmark data across the majority of test frequencies. While there are some deviations in series resistance and quality factor values, the resistor still presents a reliable option for engineers considering this particular value of resistor. However, we recommend further evaluation and test results beyond 600kHz for a complete comparison with the statistical benchmark data.

Conclusion

After a detailed assessment of the Ohmite LVM25FVR100E-TR Resistor, the technical review concludes that the component demonstrates an average performance when compared with the statistical benchmark data of resistors with the same nominal value. The metal foil composition and surface-mount package provide an advantage in terms of precision, resulting in a ±1% tolerance.

With respect to the LCR measurements, the impedance of the component stays close to the benchmark average in most test frequencies. The values at 1 Volt reveal a very slight deviation from the average impedance, but the difference becomes more pronounced at 10 Volts. These variations may translate to a slight reduction in circuit precision. It is also noteworthy that the quality factor measurements are generally lower as compared to the maximum quality factors in the benchmark, suggesting a decrease in the resonance peak of the component.

In conclusion, while the LVM25FVR100E-TR Resistor from Ohmite may not be the highest-performing resistor within its category, it does provide a satisfactory performance within the given tolerance range. Qualified engineers evaluating this resistor for use in their circuit designs should consider its impedance, quality factor, and other technical parameters in comparison with the statistical benchmark data provided. This would enable the engineers to make a more informed decision about its suitability for their application requirements.
