According to the provided data, this Resistor has a nominal value of 100m, a tolerance of ±1%, and a surface mount package size of 0805 (2012 Metric).

Our evaluation is aimed at providing electronics engineers with pertinent information on the applicability of this Resistor for their circuits. The analysis will focus on several performance factors, including resistance, inductance, and other pertinent attributes.

Pros:

• Uniform performance across various test frequencies at 1 Volt
• Good agreement within the manufacturer's specified tolerance
• Low series resistance values
• Stable quality factor across different stages of tests

Cons:

• Higher impedance values at lower test frequencies at 10 Volts
• Performance at high frequencies not available in the provided data (higher than 700 kHz) at 10 Volts
• Some level of disparity in the series capacitance values at 100 kHz test frequency

By analyzing the provided data, this review seeks to offer a thorough, informative, and honest assessment of how the Vishay Dale Thick Film Resistor RCWE0805R100FKEA stacks up against the statistical benchmark. We will delve into three main areas of analysis in the following sections: Resistance, Inductance, and Comparative Analysis.

Impedance

In this section, we will meticulously examine the impedance characteristics of the Vishay Dale RCWE0805R100FKEA Resistor alongside an indicative statistical standard. The impedance performance is highly relevant for electronics engineers when designing components and circuits that operate at various frequencies, as it directly affects the signal quality and efficiency.

Considering a 1 Volt operating condition, the analysis of the RCWE0805R100FKEA's impedance indicates a deviation from the established benchmark within the frequency range of 5Hz to 1MHz. In particular, the RCWE0805R100FKEA's impedance displays an uncharacteristic lack of exponential growth over the frequency range. The impedance remains relatively flat from 85.32m Ohms at 5Hz to 85.94m Ohms at 1MHz. Conversely, the benchmark data for comparable components of the same nominal value exhibit a more pronounced growth pattern, commencing at 91.73m Ohms at 5Hz, rising to 220m Ohms at 50kHz, and attaining a peak value of 245.6m Ohms at 1MHz.

A thorough analysis of the difference between the RCWE0805R100FKEA's impedance data and the benchmark data reveals significant discrepancies. At lower test frequencies (5Hz to 75kHz), the RCWE0805R100FKEA consistently depicts an impedance value below the benchmark average. This trend, however, inverts as the test frequency increases, as the RCWE0805R100FKEA's impedance overtakes the benchmark averages in the concluding measurements documented. Specifically, at 600kHz, the RCWE0805R100FKEA exhibits an impedance of 85.71m Ohms, which is 14.14% lower than the benchmark average value of 99.56m Ohms.

Regrettably, the provided dataset lacks impedance data for the RCWE0805R100FKEA at its maximum operating voltage, 10 Volts, beyond the 700kHz frequency range. Nonetheless, evaluation of the resistor's performance at lower frequencies suggests that the RCWE0805R100FKEA may not achieve the benchmark performance standards exhibited by other resistors in its category. Should an engineer necessitate a resistor with consistent impedance performance throughout an extended frequency range, it is advisable to explore alternative components that more effectively satisfy this criterion.

Resistance

Upon examining the nominal resistance of the RCWE0805R100FKEA Thick Film resistor, we find that it bears a value of 100 milli-Ohms and a tolerance of ±1%. Compared to the average resistance values of the benchmark dataset, it delivers a slightly superior performance. When subjected to a testing voltage of 1V, the resistor demonstrates a relatively stable resistance value across an array of test frequencies, spanning 85.33 milli-Ohms at 5 Hz to 85.34 milli-Ohms at 1 MHz. In most instances, the actual resistance values recorded are marginally lower than the average values identified within the statistical benchmark dataset for comparable components.

However, an interesting pattern emerges when evaluating this component at an increased testing voltage of 10V. The resistance values at lower frequencies either mirror or are slightly above those observed at the matching frequencies in the 1V test scenario. For example, at 5 Hz, the resistor exhibits a series resistance of 93.39 milli-Ohms, as opposed to its 1V value of 85.33 milli-Ohms. However, upon raising the frequency, an erratic shift is observed in the component's resistance values, causing them to deviate starkly from the benchmark data, particularly within the frequency range of 50 kHz to 700 kHz. At some 10V test frequencies, the component's resistance values are substantially lower than those of the statistical benchmark dataset.

Given the LCR measurements for both the 1V and 10V test scenarios, the RCWE0805R100FKEA Thick Film resistor can be lauded for its relatively stable resistance performance across diverse test frequencies at 1V. Nevertheless, users should exercise caution when deploying this component at elevated testing voltages, considering the potential for significant deviations from benchmark data at specific frequencies. Consequently, knowledgeable engineers should review the precise application requirements and circuit conditions in which they intend to use this resistor to guarantee optimal performance and dependable operation.

Inductance

In this section, we will provide an in-depth analysis comparing the inductance characteristics of the Vishay Dale RCWE0805R100FKEA resistor by delving deep into its performance metrics at various test frequencies and benchmarking against statistical performance data of other components with similar values. This comprehensive examination will reveal the strengths and challenges of the resistor in a wide array of applications and provide an educational insight into its inductive elements.

Bearing in mind that the resistor is significantly affected by test voltage and frequency, we will start with a 1 Volt test voltage applied. At an initial 5Hz test frequency, the RCWE0805R100FKEA demonstrates an inductance value of 2.943μH, which places it marginally below the benchmark average of 3.411μH. As we go on to analyze the performance of RCWE0805R100FKEA at higher frequencies, we notice a distinct shift. Between 10kHz and 1MHz, this resistor exhibits inductance values that are in close proximity to the minimum values of the benchmark, indicating less inductive behavior. For instance, the 100kHz test reveals an impressively low value of 1.585nH, which is well below the benchmark average of 6.597nH.

Transitioning to take measurements at a higher test voltage of 10 Volts, at low frequencies (specifically 5Hz and 10Hz) is quite revealing, as there is a noticeable spike in inductance values with 83.69μH and 82.63μH, respectively. This data serves as a crucial input for designers aiming for low inductance designs at lower frequencies. As the test frequency escalates to 300kHz, a value of 3.944nH is recorded, which contrasts drastically against the benchmark average of 6.338nH. This remarkably low value demonstrates the Vishay Dale RCWE0805R100FKEA's unique ability to maintain a low inductive performance at even higher test frequencies.

Overall, the Vishay Dale RCWE0805R100FKEA resistor showcases lower than average inductance values at numerous test frequencies across various voltage levels as it deviates from the statistical benchmark data. The comprehensive analysis has shown that in components where a limited inductive impedance might be advantageous, this resistor's performance could make it a valuable asset to the engineering community, and its real-world use can span a vast range of applications.
