In evaluating the impedance characteristics of the Nichicon RSS1E470MCN1GS, we performed a meticulous comparison against the impedance statistical benchmarks for similarly valued capacitors. This rigorous analysis was conducted at both 1V and 10V voltage ratings, and assessed across a range of test frequencies in order to provide a comprehensive understanding of this component's performance.

Consistently, the Nichicon RSS1E470MCN1GS Capacitor demonstrated impedance values lower than the average impedance of its benchmark counterparts at a majority of tested frequencies. For instance, at the 1V voltage rating, this capacitor reported an impedance of 304.1 Ohms at 10Hz, demonstrating a superior performance compared to the benchmark average impedance of 332.8 Ohms. As the test frequency increased, the Nichicon Capacitor maintained its impressive performance relative to the benchmark, with the impedance dropping to just 3.195 Ohms at 1kHz, compared to the 4.046 Ohm benchmark average.

At higher test frequencies, the Nichicon RSS1E470MCN1GS Capacitor's performance advantage continued to be evident over the statistical benchmark. At 20kHz, it registered an impedance of 168.7m Ohms, which was substantially lower than the 461m Ohm benchmark average. The capacitor's performance remained consistently commendable even at 300kHz, where it displayed a low impedance of 31.8m Ohms, significantly outperforming the benchmark's 289.3m Ohms.

Similar positive results were observed at the 10V voltage rating. At 20kHz, the Nichicon Capacitor reported a notable impedance of 285.7m Ohms, outpacing the average benchmark impedance of 461m Ohms. The capacitor's performance exhibited further improvements at higher test frequencies. At 100kHz, it registered an impedance of 32.59m Ohms, which was markedly lower than the benchmark average of 319.4m Ohms. It is worth emphasizing that the capacitor's impedance continued to remain below the benchmark average even at 1M test frequency, with a value of 53.57m Ohms compared to the benchmark's 286.2m Ohms.

This thorough analysis of the Nichicon RSS1E470MCN1GS Capacitor's impedance characteristics highlights its superior performance across various voltage ratings and test frequencies, contributing to an astute understanding of this component's electrical performance.

Capacitance

Upon testing the Nichicon RSS1E470MCN1GS aluminum electrolytic capacitor, it can be observed that at 1V test voltage, it indeed shows a commendable capacitance range, spanning from 55.6μF at 5Hz to as high as 161.9μF at 200kHz. It is important to note that in comparison to the statistical benchmark for similar aluminum electrolytic capacitors, the average range resides between 49.2μF at 5Hz and 68.56μF at 200kHz. The aforementioned data reveals that the RSS1E470MCN1GS consistently exhibits higher capacitance values across the entire frequency spectrum, outperforming the benchmark.

At higher frequencies, especially at 150kHz and 1V test voltage, the performance is notably superior, with capacitance values reaching 81.51μF in comparison to the benchmark's modest 33.11μF.

The Nichicon RSS1E470MCN1GS capacitor was also tested at a higher voltage, 10V, and the results were impressive. With a capacitance range consistently greater than the 1V test, the values ranged from 54.24μF at 5Hz to an impressive 241.4μF at 200kHz. Furthermore, this particular capacitor showcased exceptional capacitance values when compared to the benchmark, easily outperforming at 100kHz (55.97μF vs 30.1μF) and 200kHz (241.4μF vs 68.56μF).

The testing results clearly indicate the stable performance, higher capacitance values, and reliable operation of the Nichicon RSS1E470MCN1GS capacitor under both 1V and 10V test conditions. Considering these essential attributes, the RSS1E470MCN1GS aluminum electrolytic capacitor could be an advantageous choice for engineering projects that demand enhanced performance, higher capacitance values, and dependability for a wide range of applications.

Series Resistance

In examining the Nichicon RSS1E470MCN1GS capacitor, our analysis specifically explores the critical aspect of the capacitor's performance: Equivalent Series Resistance (ESR). The provided data for the component exhibits an intriguing performance, as the ESR at different frequencies is measured at both 1 Volt and 10 Volts. A comprehensive evaluation of the measured data allows us to compare it with industry-accepted benchmarks for similar value capacitors in the aluminum-polymer category.

For the LCR (Inductance, Capacitance, and Resistance) measurements at 1 Volt, it is evident that the Nichicon RSS1E470MCN1GS capacitor maintains a lower ESR than industry benchmarks at multiple frequencies, including 50Hz, 100Hz, 1kHz, 5kHz, 10kHz, 20kHz, and up to 100kHz. Notably, the ESR remains consistently below the maximum accepted benchmarks at all measurements. This strong performance indicates that this component delivers superior performance in terms of ESR compared to its counterparts in the Aluminum - Polymer: Polymer category.

When evaluating the capacitor's performance at an increased voltage of 10 Volts, a small deviation is observed compared to the 1 Volt measurements. At the 50Hz and 100Hz frequency bands, the component exhibits increased ESR values, rising above the average benchmark at 100Hz. Yet, this increase is within acceptable tolerances for capacitors in this category. At higher frequencies, from 50kHz onwards, the Nichicon RSS1E470MCN1GS capacitor regains its dominance with lower ESR measurements, denoting exceptional performance. This characteristic suggests that the capacitor remains suitable for a wide range of applications, particularly those that demand low ESR at higher frequencies.

Dissipation Factor and Quality Factor

An in-depth examination of the Nichicon RSS1E470MCN1GS capacitor's dissipation factor (Df) and quality factor (Q) at various frequencies and voltages yields noteworthy insights. At 1V, the Df remains low, registering a value of 0.026 at 100Hz and increasing to 0.180 at 20kHz. Given the established benchmark data, these values represent fairly solid performance. The Q demonstrates a different trend at 1V, starting with a value of 3.88 at 5Hz, peaking at 42.88 at 500Hz, and then gradually decreasing. Additionally, it is crucial to note the significant drop of Q value from 0.92 at 1MHz to 0.17 at 200kHz, which could potentially influence the capacitor's behavior in certain applications.

As the applied voltage increases to 10V, the dissipation factor displays a decrease at lower frequencies—it registers a value of 0.032 at 5Hz, which declines to 0.010 at 100Hz. However, beyond 50kHz, the Df climbs to higher values, reaching 0.570 at 100kHz. When compared to benchmark data, this trend demonstrates reasonable performance. Concurrently, the quality factor follows a similar trend with good performance at low frequencies—such as the value of 31.29 at 5Hz—before dipping to 3.73 at 50kHz, rebounding slightly, and then persistently dropping to lower values as the frequency climbs further.

In summary, understanding the observed trends in dissipation factor and quality factor for the Nichicon RSS1E470MCN1GS capacitor is crucial for selecting the appropriate capacitor for specific applications. These findings can inform guidelines for reliable performance, longevity, and overall efficiency in various electronic circuits and devices.

Upon careful analysis of the Nichicon RSS1E470MCN1GS Capacitor's LCR measurements under two voltage settings (1 Volt and 10 Volts) and comparing them to the statistical benchmark, it can be concluded that this component demonstrates strong performance in select domains.

With regard to Impedance, Series Resistance, and Series Inductance, this Aluminum - Polymer: Polymer Capacitor is quite impressive at lower test frequencies. Especially under 10 Volts, the capacitor showcases its excellent performance with lower impedance when compared to the average impedance at the same frequency ranges from the benchmark data. The Series Resistance measurements also follow suit, generally performing better than the benchmark averages.

However, when the test frequencies increase, and particularly at higher voltages, the RSS1E470MCN1GS Capacitor deviates from expectations in terms of Quality Factor, Dissipation Factor, and Series Capacitance. In these domains, the capacitor performance is slightly underwhelming, and there is room for improvement when compared to the statistical benchmark data.

In conclusion, the Nichicon RSS1E470MCN1GS Capacitor's strengths lie in its performance at lower test frequencies, as well as its low impedance and series resistance.
