Impedance

In this section, we analyze the impedance performance of the Panasonic Electronic Components ECA-1EHG470I Aluminum Electrolytic Capacitor by comparing the component's data with the statistical benchmark. Impedance is an important aspect of capacitor performance as it determines the ability of the capacitor to allow an alternating current (AC) voltage to pass through or store electrical energy efficiently. Impedance is frequency-dependent, which means it varies with frequency and affects the overall efficiency, stability, and longevity of a circuit that includes the capacitor.

Starting with the LCR measurements at 1V, we can observe that the ECA-1EHG470I shows an impedance of 655.3Ω at 5Hz, whereas the average benchmark offers 656.9Ω. At a test frequency of 10kHz, the capacitor has an impedance of 3.971Ω compared to the benchmark average of 637.7mΩ. At higher test frequencies of 750kHz and 1MHz, the ECA-1EHG470I registers impedance values of 4.847Ω and 5.052Ω, which are above the average benchmark values of 282.6mΩ and 286.2mΩ, respectively.

As for the LCR measurements at 10V, the ECA-1EHG470I exhibits varying performance characteristics. At the low-frequency range of 5Hz and 10Hz, the capacitor's impedance values are 611.4Ω and 312.4Ω, respectively. The 50Hz test result is an impedance reading of 66.66Ω, which closely aligns with the benchmark performance. Furthermore, at 1kHz, the ECA-1EHG470I demonstrates a 4.522Ω impedance value, while the average benchmark is 4.046Ω. This pattern persists throughout the frequency range, with the capacitor's impedance values trending above the average benchmarkscales across all tested frequencies.

When comparing the ECA-1EHG470I Aluminum Electrolytic Capacitor with the average benchmark impedance values, it's evident that it underperforms, particularly in its impedance readings at higher frequencies. This underperformance may lead to various effects on the overall system and limit its application in certain circuits. Further evaluation of this capacitor might entail examining how the higher impedance values influence its power dissipation capabilities, the component's temperature stability, and its reliability under different operating conditions. Users considering this capacitor for their applications should weigh its impedance characteristics against the requirements of their specific projects, keeping in mind the potential trade-offs in performance and efficiency.

In this section, we delve into the capacitance performance of the Panasonic Electronic Components ECA-1EHG470I Capacitor. Boasting a nominal value of 47μF and a tolerance of ±20% within its capacitance range, this component is an integral part of numerous electronics applications.

To evaluate its efficiency, we tested the capacitance data of the component at two distinct voltage levels, namely 1 Volt and 10 Volts. This information was then compared to statistical benchmark data for Capacitors Aluminum Electrolytic so as to assess how the component performs relative to the prevalent industry standard.

At the 1-Volt level, the ECA-1EHG470I displays a superior series capacitance compared to the average benchmark data across most analyzed test frequencies. For instance, the component's series capacitance hits 42.09μF at 500 Hz and 40.81μF at 1 kHz, outpacing the benchmark average of 41.55μF and 40.54μF, respectively. Moreover, the ECA-1EHG470I remains consistent throughout the higher frequency range, showcasing outstanding values of 36.55μF at 5 kHz and 33.24μF at 10 kHz. As a result, it surpasses the benchmark mean values of 38.46μF and 37.07μF.

Shifting to the 10-Volt level, the ECA-1EHG470I continues to demonstrate remarkable capacitance performance as it outperforms the benchmark average across a majority of test frequencies. At 50 kHz, the component's series capacitance is charted at 19.36μF, a figure that significantly transcends the benchmark data for 50 kHz. Additionally, at 250 kHz, the component exhibits a series capacitance of 6.653μF, soundly outstripping the benchmark average of 6.336μF.

In conclusion, the Panasonic Electronic Components ECA-1EHG470I Capacitor boasts top-notch capacitance performance in comparison to statistical benchmark data. Owing to its outstanding ability across various test frequencies, this aluminum electrolytic capacitor emerges as an attractive option for engineers seeking dependable and consistent capacitance for their projects.

Series Resistance

In this section, we evaluate the performance of the Panasonic Electronic Components' ECA-1EHG470I capacitor in terms of series resistance. We assess its performance against a compiled statistical benchmark at two separate voltage levels: 1V and 10V. During the assessment, we subject the capacitor to a varied range of test frequencies from as low as 5Hz to as high as 600kHz in order to evaluate its behavior extensively.

At the 1V voltage level, the ECA-1EHG470I capacitor presents a higher series resistance when compared to the statistical benchmark at lower frequencies of 5Hz and 10Hz. This finding suggests less efficient energy transfer in the device at these low frequencies. However, as the frequency increases from 20Hz onwards, the ECA-1EHG470I's series resistance performance gradually improves, with results falling below the statistical benchmark starting from 50Hz, and maintaining this improved performance up until 600kHz. This observed enhancement in performance at higher frequencies is particularly beneficial for electronic applications that demand rapid charging and discharging rates.

On the other hand, at the 10V voltage level, the ECA-1EHG470I capacitor exhibits a lower series resistance compared to the statistical benchmark across most of the analyzed test frequencies. Beginning from the 50Hz frequency and extending beyond, the capacitor maintains a more consistent resistance value, which translates to stable performance within this range. This stable performance accompanied by less energy loss implies improved efficiency, making the ECA-1EHG470I capacitor a suitable candidate for demanding high-voltage applications where reliable power delivery and energy conservation are crucial factors.

Dissipation Factor and Quality Factor

LCR measurements taken at 1 Volt revealed that the ECA-1EHG470I exhibited a Dissipation Factor (Df) of 0.090 at a test frequency of 5 Hz. At the same test frequency, the Quality Factor (Q) was observed to be 10.98. It is notable that the performance of the component changes as the test frequency increases, displaying values such as 0.170 Df and 6.10 Q at 10 Hz, 0.538 Df and 1.85 Q at 500 Hz, and 1.018 Df and 0.99 Q at 1 kHz. The Quality Factor demonstrates a steady decline as the frequency increases beyond 1 kHz, plummeting to as low as 0.01 Q at 700 kHz and higher frequencies.

In contrast, LCR measurements taken at 10 Volts indicate a similar trend, but with a lower initial Df of 0.068 and a higher initial Q of 14.53 at 5 Hz. Values for these parameters in this configuration include 0.062 Df and 16.13 Q at 10 Hz, 0.382 Df and 2.79 Q at 500 Hz, and 0.597 Df and 1.60 Q at 1 kHz. As the test frequency escalates above 1 kHz, the Quality Factor exhibits a drop akin to the 1 Volt measurements, with values hovering around 0.02 Q at high frequencies such as 1 MHz.

When comparing the ECA-1EHG470I's Dissipation Factor to prevailing statistical benchmark data for Aluminum Electrolytic Capacitors, it is found to be in line with components in the same category. However, the Quality Factor at higher frequencies displays a lower value, which might limit its suitability for specific applications where maintaining high Q values is crucial. Hence, it is essential for engineers to thoroughly assess the performance of this component in relation to the specific requirements of their circuits when evaluating the ECA-1EHG470I for potential usage.
