Impedance

Upon examining the Yageo RL1206FR-7W0R1L thick film resistor LCR measurements at 1 Volt input, a compelling pattern emerges. The component data reveals an overwhelmingly consistent performance across the explored frequency domain, as the impedance of the resistor maintains values between 104.4m and 105.1m across all frequencies tested. While such consistency is certainly notable, comparison to the provided statistical benchmark data requires closer scrutiny, emphasizing the importance of understanding impedance behavior in practical applications.

A significant aspect that should be highlighted when comparing the Yageo RL1206FR-7W0R1L resistor to the benchmark is its impedance performance. Within the tested frequency range of 5 Hz to 1 MHz, the resistor consistently performed at the high end of the spectrum with values nearby or equivalent to the maximum impedance (Ohms) figures from the benchmark. This suggests that this particular resistor's impedance margins are far-reaching and could meet the demands of a wide array of engineering requirements.

At the lower frequencies (5 Hz to 100 Hz), the RL1206FR-7W0R1L's impedance ranges from 104.4m to 104.7m, reaching the benchmark's maximum values. As the frequency increases, the component maintains a stable performance with only minor variations in impedance. This is indicative of the resistor's inherent ability to adapt to different frequency inputs, reinforcing the resistor's strong performance within the statistical data set. Additionally, the impedance never drops below the benchmark's average impedance values, further highlighting the component's reliability and consistency.

When comparing the resistor's LCR Measurements at 10 Volts, we can observe that the impedance values show fluctuations at varying frequencies. Nonetheless, the data still demonstrates a profound level of consistency, particularly in the middle frequency range where minimal deviation occurs. This observation is instructive, as it demonstrates the importance of considering higher voltage input variations when assessing a component's impedance behavior.

The Yageo RL1206FR-7W0R1L thick film resistor exhibits an expert and solid impedance performance in comparison to the statistical benchmark. The consistency in performance across the various frequencies emphasizes the resistor's quality and its ability to meet a wide range of engineering needs for degreed engineers seeking optimal components for their products. This understanding of impedance performance provides a transparent and authoritative view on one of the crucial aspects to consider when selecting electronic components with confidence.

Resistance

Upon conducting a thorough analysis of the LCR measurements at 1 volt, the RL1206FR-7W0R1L resistor displays a resistance on the higher end of the spectrum when compared to the average performance. Spanning across a frequency range of 5 Hz to 1 MHz, the resistor's values are found to lie within the range of 104.2 mΩ and 104.6 mΩ. It is essential to highlight that the maximum resistance values within the statistical benchmark data are fairly close to the values obtained during our tests. On the other hand, the RL1206FR-7W0R1L resistor's performance significantly exceeds the minimum and average benchmark data values.

Moreover, upon examining the LCR measurements at 10 volts, the RL1206FR-7W0R1L resistor exhibits an increased resistance in lower frequency ranges compared to the benchmark data. The measurements underscore that the resistance values are remarkably higher when contrasted with the minimum and average values from the statistical benchmark. This demonstrates the impact of input voltage on the resistor's performance, suggesting that the resistor could potentially exhibit a non-linear resistance characteristic.

It is crucial for engineers to consider the performance attributes and operating conditions of this specific resistor when incorporating it into their designs. Depending on the proposed application, the RL1206FR-7W0R1L may display a varying degree of resistance value, which must be accounted for, in order to ensure proper functioning of the overall electronic system. Furthermore, engineers should assess the impact of temperature variation on resistance and consider employing temperature compensation techniques if needed.

Inductance

In the RL1206FR-7W0R1L resistor, at a 1-volt test frequency, the measured series inductances display higher values than the average inductance across the majority of test frequencies. This pattern is noticeable except at a frequency of 5 Hz, where the RL1206FR-7W0R1L has an inductance of 3.828μH. This value is slightly higher than the average of 3.411μH, but still falls within the acceptable min-max range of 1.638μH to 5.906μH. In comparison, the resistor exhibits considerably higher inductances at other test frequencies, particularly at 10 Hz and 50 Hz, with values of 1.022μH and 383.9nH in contrast to the average values of 868.9nH and 598.7nH, respectively.

When we examine the series inductance of the RL1206FR-7W0R1L in higher frequency ranges, we see that it adheres more closely to the average values. At 200 kHz, for example, the resistor registers an inductance of 2.016nH, only slightly deviating from the average of 6.397nH. Furthermore, as the test frequency reaches 1 MHz, the inductance of the Yageo resistor aligns more closely with the benchmark average, although minor discrepancies are seen around 650 kHz and 900 kHz frequencies.

An important factor to consider is how inductance performance changes if the test voltage for the RL1206FR-7W0R1L is changed from 1 volt to 10 volts. At lower test frequencies, such as 5 Hz and 10 Hz, the inductance values increase considerably, reaching 85.86μH and 83.75μH, which are significantly higher than their corresponding values at 1 volt. In contrast, when the test frequency goes beyond 50 Hz, the inductance values become more similar to those at 1 volt, ultimately stabilizing in the nano-Henry range. As observed earlier, the inductance values continuously stay within the min-max range, which testifies to the component's reliability and compliance with industry benchmarks.

Comparative Analysis

In our comparative analysis, we will be evaluating the performance of the Yageo RL1206FR-7W0R1L Thick Film Resistor against a statistical benchmark compiled from other components of the same value. The RL1206FR-7W0R1L has a nominal value of 100m with a tolerance of ±1% and utilizes surface mount technology within a 1206 (3216 Metric) package.

With close examination, we can observe that the RL1206FR-7W0R1L underperforms when compared with the average impedance values of the statistical benchmark, ranging from 5Hz to 1MHz at 1V. The resistor demonstrates an impedance of 104.7mΩ, progressively increasing to 105.1mΩ at 1MHz, all consistently higher than the benchmark average values.

Furthermore, the RL1206FR-7W0R1L consistently trails the benchmark when evaluating the various test frequencies and their corresponding series resistance measurements. It remains above average in its values across the entire frequency range.

Regarding the series inductance measurements, while the RL1206FR-7W0R1L initially displays exceptionally high values at lower test frequencies (3.828μH at 5Hz and 1.022μH at 10Hz), it remains on par with the benchmark throughout the remaining frequency range. However, it is important to note that these high values under those lower test frequencies may potentially affect the overall circuit behavior, depending on the application the resistor is incorporated into.

Focusing on the RL1206FR-7W0R1L's capacitance measurements at 1V test voltage, the resistor demonstrates a peak series capacitance of 6.97F at 1kHz, which dissipates completely across the range of higher test frequencies. This is indicative of relatively stable capacitance values throughout most frequency ranges when compared to the benchmark.

Upon examining the LCR measurements of the RL1206FR-7W0R1L at 10V test voltage, we can observe that the resistor has a higher impedance at lower frequency ranges when compared to those of the benchmark. The series resistance measurements, however, follow a similar pattern as observed at the 1V test voltage. They remain consistently above the benchmark's statistical average and increase gradually as the test frequency escalates.

In conclusion, based on the comparative analysis, the Yageo RL1206FR-7W0R1L Thick Film Resistor underperforms in certain aspects when evaluated against the statistical benchmarks. This includes higher impedance and series resistance measurements across the comprehensive frequency range. However, its stable capacitance values and comparable inductance measurements at higher frequencies could potentially serve as compensating factors, depending on the intended application of this resistor in any specific circuits. Ultimately, engineers should carefully consider these findings when evaluating the RL1206FR-7W0R1L Thick Film Resistor for use in their circuits.

Conclusion

After evaluating the Yageo RL1206FR-7W0R1L resistor's performance against the statistical benchmark, it can be concluded that this 100m Ohms, ±1% tolerance, thick film 1206 (3216 Metric) style surface mount resistor's performance is within the expected range for similar components at some frequencies, while performing better or worse at other frequencies.

At most frequencies below 500kHz, it demonstrates impedance and series resistance values relatively close to the benchmark average. Particularly under test frequencies of 1kHz and 100kHz, the RL1206FR-7W0R1L showed competitive performance on quality factor, series resistance, and serious capacitance when compared to the statistical benchmark values.

However, when observing frequencies at and above 500kHz, the resistor's impedance, series resistance, and quality factors reveal modest increases compared to the statistical benchmark. Consequently, this might cause undesirable power dissipation at higher frequencies in some applications.

In conclusion, although RL1206FR-7W0R1L may not be an ideal solution for high-frequency applications, it can be considered as a reliable option for applications requiring a thick film surface mount resistor within the lower frequency range.
