Impedance

The Würth Elektronik 875075555002 aluminum-polymer capacitor was thoroughly tested for impedance at two different voltage levels, 1V and 10V, across various frequencies. Subsequently, the results were compared and analyzed against a statistical benchmark of components with the same capacitance value.

When tested at 1V, the 875075555002 capacitor exhibited an impedance of 645.6 Ohms at 5Hz, 325.9 Ohms at 10Hz, and 66.49 Ohms at 50Hz. In comparison, the average impedance benchmark for similar capacitors was 656.9 Ohms, 332.8 Ohms, and 69.54 Ohms at the corresponding frequencies. These results indicate that Würth Elektronik's capacitor delivers slightly better performance in terms of low-frequency impedance compared to other capacitors in the statistical range.

Continuing the measurements up to 100kHz, it was observed that the 875075555002 capacitor's impedance either matched or slightly outperformed the average benchmarks at these frequencies. However, at frequencies beyond 100kHz, the performance showed a small increase in impedance compared to the average benchmark, particularly in the 300kHz to 600kHz range. Nevertheless, at a frequency of 1 MHz, the tested capacitor exhibited an impedance of 74.38m Ohms, which is relatively close to the average benchmark impedance value of 286.2m Ohms.

Upon conducting LCR measurements at 10V, the Würth Elektronik capacitor showed significant improvements in impedance across a wide frequency range when compared to its 1V counterpart. In the lower frequency range, the capacitor's impedance was consistently lower than the statistical benchmark, and this trend prevailed up until approximately 50kHz. Additionally, the impedance performance in the higher frequency range, between 100kHz and 1MHz, was observed to closely follow the statistical benchmarks.

In summary, the Würth Elektronik 875075555002 aluminum-polymer capacitor demonstrates an impedance profile that generally outperforms or aligns with the statistical benchmarks across a broad range of frequencies, particularly in the lower frequency domain. However, there is potential for performance improvement in the higher frequency range beyond 100kHz. Therefore, this capacitor would be an ideal candidate for numerous electronics applications, provided the impedance requirements fall within the performance parameters observed during the testing process.

Capacitance

Within low test frequencies ranging from 5 to 100Hz, the 875075555002 capacitor maintains a relatively stable capacitance value, fluctuating between 47μF and 49μF. When tested at a voltage of 1 Volt, its series capacitance values fall within the average benchmark values across these frequencies. Notably, the series capacitance peaks at a frequency of 50kHz, measuring 47.25μF. Nevertheless, when examining frequencies above 100kHz, the capacitance of the 875075555002 component exhibits a significant deviation from the benchmark, as its values greatly exceed the average series capacitance for the respective frequencies.

As an example, at a test frequency of 150kHz, the measured capacitance rises to 103.7μF, which is considerably higher than the average benchmark capacitance of 33.11μF at the same frequency. Moreover, at 200kHz, the capacitor's capacitance value escalates to an impressive 1.767mF, contrasting with the 68.56μF average. It is essential to emphasize that data for the component’s series capacitance at frequencies of 250kHz and above, when tested at 1 Volt, is unavailable.

Alternatively, when the capacitor is tested at 10 Volts instead of 1 Volt, its capacitance values generally display consistent performance within the low-frequency range. However, as the test frequency approaches 50kHz, the observed series capacitance transitions, peaking at 45.19μF. Overall, the capacitor tends to exhibit lower capacitance values compared to those measurements obtained at 1 Volt. Similarly to the 1-Volt measurements, there is no available data for frequencies beyond 150kHz when tested at 10 Volts.

In summary, the 875075555002 aluminum-polymer capacitor showcases fairly consistent capacitance values within low-frequency ranges, making it a viable option for applications demanding stability within these frequency ranges. However, for applications necessitating stable capacitance over broader frequency ranges, the 875075555002 capacitor may not be the optimal selection, due to its substantial deviation from the average benchmark values at higher frequencies.

Series Resistance

The 875075555002 Capacitor demonstrates exceptional performance with respect to its Series Resistance at a wide range of test frequencies, particularly when compared to the statistical benchmark data of similar capacitors. By examining the capacitor's performance under varying test conditions, such as different applied voltages and frequencies, we can gain a better understanding of its suitability for certain applications.

When the 875075555002 Capacitor is measured at 1 Volt, it consistently surpasses average Series Resistance values across the majority of the test frequencies. For instance, at a 50Hz frequency, the capacitor boasts an impressive Series Resistance of 1.132Ω, which notably outperforms the average value of 3.037Ω. Furthermore, the component demonstrates equally remarkable performance at higher frequencies such as 1MHz, maintaining a Series Resistance of 43.1mΩ as opposed to the average of 280.2mΩ. This distinct advantage showcases the component's particular effectiveness in high-frequency applications.

Examining the 875075555002 Capacitor measurements at an increased applied voltage of 10 Volts also reveals a superior performance compared to the statistical benchmark in numerous test cases. At 50Hz, the capacitor attains a Series Resistance of 1.616Ω, a considerable improvement over the average value of 3.037Ω. It continues to outshine its counterparts at higher frequencies such as 100kHz, achieving a Series Resistance of 17.51mΩ as opposed to the average of 298.3mΩ.

In conclusion, the 875075555002 Capacitor exhibits outstanding performance in terms of Series Resistance when matched against the statistical benchmark data across a variety of frequencies and applied voltages. These results distinguish it as a highly advantageous option for engineers in search of an Aluminum - Polymer: Polymer Capacitor with low Series Resistance. This is particularly relevant for those aiming to employ such a component in high-frequency applications, where the superior performance can greatly contribute to overall system efficiency and functionality.

Dissipation Factor and Quality Factor

In this section, we will discuss the dissipation factor (Df) and quality factor (Q) of the Würth Elektronik 875075555002 capacitor over a range of test frequencies between 5 kHz and 1 MHz, with voltage levels of 1 Volt and 10 Volts applied across it. Comparing the obtained values against industry benchmarks will help in determining if this capacitor is an optimal choice for certain applications.

When operating at 1 Volt, the 875075555002 capacitor demonstrates a Df ranging from 0.017 to 0.026 at test frequencies between 50 Hz and 1 kHz. This indicates a good performance and reasonable energy efficiency within this frequency range, which is generally desirable. However, as the frequency increases from 1 kHz to 20 kHz, the Df value exhibits an upward trend, ranging from 0.026 to 0.171. At the test frequency of 100 kHz, we observe the highest Df value of 1.069, which hints at a higher energy dissipation level and reduced efficiency at this frequency.

Moving on to the quality factor, at a test frequency of 5 Hz and 1 Volt applied voltage, the capacitor boasts a Q value of 46.83, which then progressively increases to 60.24 at 100 Hz. As the frequency rises, the Q value experiences a slight decrease, ultimately reaching the lowest value of 0.35 at 150 kHz. This pattern indicates that the capacitor's performance degrades with increasing frequencies.

At an applied voltage of 10 Volts, we note a similar trend as observed earlier. The Df between 50 Hz and 100 Hz ranges from 0.026 to 0.009, contributing to satisfactory performance at these frequencies. The quality factor values also reveal a peak of 108.99 at 100 Hz, followed by a drop as frequency increases up to 1 MHz.

Relative to industry benchmarks, the Würth Elektronik 875075555002 capacitor presents a commendable performance at lower frequency ranges, specifically below 1 kHz where it exhibits a suitably low Df and an acceptable quality factor. However, its performance experiences a marked decline at higher frequencies that demonstrate a more pronounced rise in Df and a degradation in Q. Engineers should take these findings into account when deciding if the 875075555002 capacitor is apt for their specific application requirements, particularly at higher frequency ranges.
