• Good performance with low series resistance at high frequencies

Cons:

• High Dissipation Factor at higher frequencies
• Lower Quality Factor at certain frequencies compared to benchmark

Considering this analysis, the 865060443004 Capacitor may still be a viable option for qualified engineers proficiently working in the domain of Aluminum Electrolytic Capacitors for use in their circuits. This review aids in augmenting the statistical benchmark data and makes informed decisions for interested individuals.

Impedance

At lower frequencies (5 Hz to 500 Hz), the Würth Elektronik 865060443004 Aluminum Electrolytic Capacitor performs fairly closely to the average benchmark impedance. This can be observed at 100 Hz where the component impedance is 34.41 Ohms, while the average benchmark impedance for the same frequency is 35.87 Ohms. Similarly, at 500 Hz, the component presents 7.089 Ohms versus the 7.777 Ohms average benchmark impedance. It is important to mention that in certain applications and design requirements, even minor impedance differences can result in significant performance variation.

However, as we move higher in frequency, the capacitor performs significantly better than the statistical benchmark in certain frequency ranges. For instance, at 1 kHz, it accounts for a noteworthy impedance of 3.649 Ohms compared to the average benchmark impedance of 4.046 Ohms. This difference can be crucial for applications where tighter tolerances or enhanced frequency response is required.

Even more remarkable is the difference at 20 kHz, where the 865060443004 LCR measurement is notably lower than the benchmark - 636.6 mOhms compared to 461 mOhms. The same trend can be observed at higher frequencies nearing 1 MHz. These lower impedance values at higher frequencies suggest that this capacitor is effective in suppressing high-frequency noise and maintaining stable voltage at desired levels.

Although the capacitor has a slightly higher impedance at higher test frequencies like 1M (460.7 mOhms vs 286.2 mOhms), the overall better performance across multiple frequency ranges draws attention to this component as a standout performer compared to the average benchmarks. Consequently, engineers can consider Würth Elektronik's 865060443004 Aluminum Electrolytic Capacitor as a potential choice when seeking optimal performance in impedance-sensitive applications, especially in lower to mid-frequency ranges. This insight might not only help to enhance the stability and efficiency of electronic systems but also meet strict regulatory standards applicable to various industries.

Capacitance

The Würth Elektronik 865060443004 aluminum electrolytic capacitor, boasting a nominal capacitance value of 47μ Farads, underwent LCR measurements, which were conducted at 1 V and 10 V across various test frequencies. The data gathered was then compared to a statistical benchmark rooted in capacitance values from components of a similar nature.

At the first test performed at 5 Hz, the capacitor displayed a capacitance of 47.89μ Farads at 1 V—falling relatively close to the benchmark dataset's average value of 49.2μ Farads. Moving up to the 10 Hz test frequency, the capacitance diminished slightly to 47.47μ Farads, landing just below the benchmark's mean of 48.14μ Farads.

With further increases in test frequency, reaching 50 Hz and 100 Hz, the capacitor's capacitance demonstrated a subtle downward deviation relative to the benchmark averages. Interestingly, at 500 Hz and 1 kHz test frequencies, the component's performance remained well within the average range. This behavior adhered to the benchmark dataset's norm, displaying average capacitance values of 41.55μ and 40.54μ Farads, respectively.

Delving into test frequencies between 5 kHz and 20 kHz, it was observed that the capacitor continuously fell short of the benchmark averages. Peak discrepancies occurred at 10 kHz and 20 kHz. During these tests, the performance measurements resulted in capacitances of 37.93μ and 33.28μ Farads, which were notably lower than the respective benchmark averages of 38.46μ and 35.09μ Farads.

As the test frequencies entered the higher range of 50 kHz to 75 kHz, the 865060443004 capacitor maintained its downward trend, with performance outcomes marginally underperforming in comparison to the benchmark averages. Nevertheless, from 100 kHz onwards, an intriguing pattern emerged as the capacitor deviated favorably from the statistical benchmark. At 700 kHz test frequency, the component reached an exceptional capacitance of 114.5μF, placing it well above the benchmark average.

Upon analyzing the data comprehensively, the 865060443004 capacitor offers competitive capacitance values within the lower frequency range. However, it also reveals shortcomings - particularly within the mid to high-frequency range - when compared to the benchmark dataset. These disparities may potentially impact the capacitor's effectiveness in specific spectral applications. Therefore, when determining the component's aptness, the importance of these factors ought to be weighed against the overall performance and application requirements of the intended use.

Series Resistance

In the case of the 865060443004 Capacitor, the series resistance depends on the test frequency ranging from 5 Hz to 1 MHz. It is worth examining the capacitor's performance in varying frequency ranges to gain a better understanding of its strengths and weaknesses.

When looking at test frequencies between 5 Hz to 1 MHz, we can observe that the 865060443004 Capacitor exhibits a lower level of series resistance compared to the maximum benchmark values. This is especially noteworthy in frequencies between 10 Hz and 20 kHz, where the capacitor stands out with lower resistance compared to the average values at those frequencies, indicating superior performance.

At lower test frequencies between 5 Hz and 10 Hz, the 865060443004 Capacitor's series resistance falls between the minimum and average benchmark values. This implies that there might be some room for improvement at very low frequencies. However, when observing results at 1 kHz and beyond, the series resistance lies between the minimum and average benchmark values, indicating better overall performance compared to other components in the market.

Moving on to the evaluation of the capacitor at 10 Volts, the series resistance figures show a gradual decrease when test frequency increases. Although performance at low frequencies such as 5 Hz, 10 Hz, and 50 Hz is not as impressive, the 865060443004 Capacitor showcases excellent performance in the frequency range of 100 Hz to 20 kHz. Additionally, between 20 kHz and 100 kHz, it displays a minor increase in series resistance, which demonstrates a good level of stability over a wide frequency range. This is a remarkable quality in electronic components, as it ensures reliability and consistent performance across various applications.

Dissipation Factor and Quality Factor

The Würth Elektronik 865060443004 Capacitor demonstrates a promising dissipation factor (Df) range when tested with 1V. Under the low-frequency test condition, the initial Df values consistently fall into the range between 0.022 (at 5Hz) and 0.210 (at 1kHz), indicative of low energy loss in the capacitor. However, it is important to note that at higher test frequencies, the Df values significantly increase, reaching values as high as 9.753 (at 250kHz). Comparatively, the 865060443004 displays competitive and adequate results when considering similar Aluminum Electrolytic capacitors in the market.

At lower frequencies, the 865060443004 displays quite promising Quality Factor (Q) values, a metric used to evaluate the efficiency and performance of capacitors. Scores ranging from 45.90 (at 5Hz) to 4.76 (at 1kHz) indicate that capacitor performance is up to market benchmarks. It is important to note, however, that the Q values tend to significantly decrease with increasing frequencies, reaching values as low as 0.01 (at 650kHz). These values suggest that the component may not be well-suited for high-frequency applications.

Engineers seeking capacitors for low to mid-range frequencies might wish to include this component in their evaluation process. However, for applications where high-frequency operation is critical, particularly in terms of Quality Factor, it is advisable to assess alternative capacitors to ensure optimal performance under such conditions.
