Impedance

An in-depth analysis of the impedance values of the RL1220S-R10-F inductor, considering the statistical benchmark data and LCR measurements at 1 Volt, reveals its excellent impedance stability. With its nominal impedance set at 100 milli-Ohms and a tight tolerance of ±1%, it is evident that the majority of impedance values across the specified frequency range remain well within the permissible limits.

While testing the impedance at a 1 Volt frequency, the performance closely follows the average impedance benchmark. The values consistently stay within the minimum and maximum impedance tolerance range. For instance, at a frequency of 50 kHz, the measured impedance is 87.73 milli-Ohms, which is squarely centered in the impedance range. Additionally, in the frequency spectrum of 5 kHz to 100 kHz, the impedance values exhibit minimal fluctuation, thus, indicating a stable performance.

However, the observed behavior of impedance values during LCR measurements at 10 Volts presents a more diverse and contrasting pattern compared to the benchmarks. Within the test frequencies of 5 kHz and 10 kHz, the recorded impedance range remains within the expected values. Surprisingly, at a test frequency of 20 kHz, the impedance sharply increases to 98.23 milli-Ohms, significantly exceeding the average value – a strong indication of possible performance variations at higher voltage levels. Moreover, impedance values at test frequencies ranging from 50 kHz to 100 kHz consistently stay below the benchmark minimums.

Across a wide range of test frequencies at 1 Volt, the impedance performance showcases remarkable stability. However, the observed inconsistencies and variability of impedance values at 10 Volts necessitate additional examination and analysis – particularly when designing and evaluating applications with higher voltage requirements – to ascertain whether these variations translate into potential drawbacks in specific electronic applications or if they pose a risk for suboptimal performance.

Resistance

When examining the RL1220S-R10-F’s resistance in comparison to statistical benchmarks at 1 Volt, it demonstrates a relatively consistent performance across various test frequencies. The values tend to be in the vicinity of the average resistance, showcasing the effectiveness of this thin-film resistor. For instance, for the low-frequency range that encompasses 5 Hz, 10 Hz, and 50 Hz, the RL1220S-R10-F exhibits series resistances of 87.35mΩ, 87.52mΩ, and 87.73mΩ, respectively. These values fall below the respective benchmark average values of 91.71mΩ, 92mΩ, and 92.09mΩ, nevertheless, it still maintains good stability.

In the mid-frequency range, the RL1220S-R10-F continues to display consistency in its resistance performance. As a prime example, at 1 kHz, 5 kHz, and 20 kHz, it presents closely clustered series resistances of 87.71mΩ, 87.77mΩ, and 87.76mΩ, respectively. While deviating slightly from the nominal 100mΩ, these values further emphasize the component's suitability for applications with average resistance deviation requirements.

Moving on to a 10 Volt test scenario, the RL1220S-R10-F's series resistance exhibits slight variations when subjected to higher test frequencies compared to the statistical benchmarks. For instance, at 50 kHz, the resistor displays a remarkable value of 78.95mΩ, which is substantially lower than the benchmark average of 92.15mΩ. Similarly, when tested at 600 kHz, it delivers a resistance value of 80.37mΩ, which is found to be below the statistical average of 93mΩ. It is essential for engineers to consider these variations while designing systems that require specific resistance values when operating at higher frequencies.

Inductance

Starting with the inductance values evaluated at a 1 Volt test frequency, it can be observed that the RL1220S-R10-F exhibits lower inductance in comparison to the statistical average across a wide range of frequencies. For instance, at a frequency of 100 kHz, this component's series inductance measures 1.5 nH, a value that falls between the benchmark's minimum (1.119 nH) and average value (6.597 nH). This pattern continues when using a higher test frequency of 1 MHz, as the measured series inductance comes in at 1.526 nH, remaining well within the range of the statistical minimum (1.238 nH) and average (6.152 nH).

When the test frequency is increased to 10 Volts, only a limited range of measurements is available for analysis, and more significant differences start to appear. For instance, at 100 kHz, the RL1220S-R10-F exhibits a series inductance of 318.3 nH, which is higher than the benchmark average value measured at the 1 Volt test frequency. Likewise, at a test frequency of 200 kHz, the component's series inductance measurement of 2.534 nH also surpasses the 1 Volt benchmark's average (6.397 nH).

It is important to mention that the data for RL1220S-R10-F at a 10 Volt test frequency is limited, constraining our ability to draw comprehensive conclusions about its performance at higher voltages. However, based on the available information, the RL1220S-R10-F demonstrates lower inductance values when compared to the statistical benchmark at a 1 Volt test frequency, with some variations appearing at higher voltage levels.

This characteristic can be beneficial for engineers seeking a component with reduced inductance to incorporate into their designs. Yet, to accurately assess the overall performance of this component relative to its statistical benchmark, a more comprehensive dataset, especially for higher voltage levels, would be required.

Comparative Analysis

In this comparative analysis, we will examine the performance of Susumu's Thin Film Resistor, RL1220S-R10-F, against the provided statistical benchmark data. The RL1220S-R10-F offers a nominal value of 100m Ohms with a tolerance of ±1%, and it is a surface mount component in an 0805 (2012 Metric) package.

When comparing the average impedance values at 1 Volt, the RL1220S-R10-F exhibits performance that is generally within the same range as the benchmark values. For example, at a test frequency of 5 kHz, the RL1220S-R10-F demonstrates an impedance value of 87.78m Ohms, compared to the benchmark average of 91.94m Ohms. Similarly, at 100 kHz, the component's impedance is slightly lower than the benchmark average, sitting at 87.75m Ohms compared to 92.53m Ohms. These variations in impedance do not appear to be significant enough to strongly impact the overall performance of the resistor in most applications.

It is worth noting that the RL1220S-R10-F does exhibit a lower average series resistance across most test frequencies when compared to the benchmark data. At 1 kHz, for instance, the RL1220S-R10-F shows a series resistance of 87.71m Ohms, while the benchmark average is slightly higher at 91.83m Ohms. This difference is even more pronounced at higher test frequencies, such as 20 kHz, where the RL1220S-R10-F resistor posts a series resistance of 87.76m Ohms compared to the benchmark's 92.07m Ohms. Lower average series resistance may prove advantageous in certain applications as it can contribute to reduced power losses.

Another noteworthy aspect of the RL1220S-R10-F's performance is found in its series inductance values. Generally, the RL1220S-R10-F displays higher inductance values compared to the benchmark at lower test frequencies (below 1 kHz). For example, at a test frequency of 10 Hz, the RL1220S-R10-F presents a series inductance value of 653.1n Henries, while the benchmark sits at just 868.9n Henries. However, in higher frequency applications, above 1 kHz, the Susumu resistor's series inductance values remain closer to the benchmark averages.

In conclusion, Susumu's RL1220S-R10-F Thin Film Resistor demonstrates performance that is generally comparable to the provided statistical benchmark data. Key distinctions include the RL1220S-R10-F's lower average series resistance values and slightly higher average series inductance values at lower test frequencies. Nevertheless, these minor differences should not significantly impact the resistor's overall suitability in a wide range of circuit designs and applications.

In conclusion, the Resistor under review, Susumu's RL1220S-R10-F Thin Film Resistor, exhibits a mixed performance when evaluated against the provided statistical benchmark data. The RL1220S-R10-F's impedance and resistance characteristics are, for the most part, in line or slightly higher than the average when operating at 1 Volt across a wide frequency range. However, when the voltage is increased to 10 Volts, the Resistor's impedance seems to vary significantly across the frequency spectrum, shedding light on potential performance inconsistencies at higher voltages.

When analyzing LCR measurements conducted at 10 Volts, it is worth noting that an array of related values, like series inductance and series capacitance, deviate from the statistical benchmark values. As a positive aspect, the Resistor exhibits an exceptionally low Dissipation Factor and overall minimal Quality Factor variation among different test frequencies, indicating a lower energy loss during the operation. These characteristics make it especially interesting for engineers who are looking for resistors with low energy loss while considering their impact on overall circuit performance.

To summarize, the Susumu RL1220S-R10-F Thin Film Resistor might be a suitable candidate for engineering applications requiring stable performance under lower voltages, while its performance at higher voltages necessitates further evaluation. Moreover, the device would be advantageous for applications aiming to minimize energy loss. Ultimately, it is crucial for engineers to scrutinize the provided data and compare the Resistor with the statistical benchmark to make an informed decision based on the specific requirements of their projects.
