Introduction

The purpose of this technical review is to provide an in-depth performance analysis of the Würth Elektronik 865080443007 Capacitor, an Aluminum Electrolytic component with a nominal capacitance value of 47μ and a voltage rating of 25V. The primary aim is to assist electronics engineers in determining whether this capacitor is suitable for their needs.

By comparing the comprehensive test results against the provided statistical benchmark data, the review will identify areas where the component excels, and aspects that may require additional consideration. This analysis will utilize LCR measurements conducted at two different voltage levels (1V and 10V) and frequency range from 5Hz to 1MHz.

The review is organized into four main sections: Capacitance, Series Resistance, Dissipation Factor and Quality Factor, and Comparative Analysis. While the individual sections provide an exhaustive examination of the capacitor's performance, readers may choose to focus on the aspects that are most relevant to their particular applications.

• Pros:
• Wide frequency range and stable capacitance values
• Low impedance across most frequencies
• Higher quality factor for lower frequency range

• Dissipation factor increases considerably at higher frequencies
• Quality factor drops dramatically at higher frequencies
• Series resistance shows some variation across the frequency spectrum, especially in higher frequencies

Impedance

In this section, we thoroughly analyze the impedance performance of the Würth Elektronik Capacitor, specifically with the part number 865080443007. Utilizing the provided LCR measurements at 1 Volt and 10 Volts, a comparison is made between the capacitor's impedance and statistical benchmark data, which can offer insights into the capacitor's effectiveness across different test frequencies. In general, it is observed that the capacitor exhibits increased impedance values compared to the average values at the same test frequency.

For instance, when the test frequency is 100 Hz and the voltage is 1 Volt, the capacitor's impedance measures 36.31 Ohms, which is marginally higher than the benchmark average value of 35.87 Ohms. Likewise, at 10 Volts and 100 Hz, the impedance measures 35.69 Ohms, which remains higher than the benchmark.

Interestingly, the capacitor demonstrates relatively better performance within particular frequency ranges of higher values. For instance, at 1 Volt and 20 kHz, the capacitor measures an impedance of 710.2 milliohms, which falls notably lower than the 461 milliohms benchmark value. Furthermore, the measured impedance decreases to 399.8 milliohms at a higher voltage of 10 Volts and 20 kHz, surpassing the benchmark value by a greater margin.

Conversely, some test frequencies reveal less optimal impedance measurements. For example, the capacitor exhibits an impedance of 633.8 milliohms at 1 Volt and 50 kHz, a value comparatively higher than the benchmark average of 344.1 milliohms. In addition, at 10 Volts and 50 kHz, the capacitor's impedance reaches 627.9 milliohms, which also falls short compared to the benchmark data.

Taking these factors into consideration, the Würth Elektronik Capacitor, part number 865080443007, exhibits a mixed performance compared to the statistical benchmark data. Although the component showcases improved impedance behavior in specific higher frequency ranges, a number of test frequencies simultaneously indicate less optimal results, when juxtaposed against average values. Consequently, engineers should thoroughly evaluate these impedance characteristics to determine whether this particular capacitor is suitable for their desired applications.

Capacitance

In order to assess the performance of Würth Elektronik's 865080443007 Capacitor, we compared its capacitance properties with other components of the same value category by analyzing LCR measurement data. The LCR measurements were taken at 1 Volt and 10 Volts to provide a detailed evaluation of the capacitor's performance under different voltage conditions.

When testing frequencies from 5 Hz to 20 kHz, the measured capacitance values range from 21.49 μF - 45.31 μF, which are mostly above or within the average benchmark range for capacitors of this type. This suggests that the 865080443007 Capacitor exhibits satisfactory performance in low to mid-range frequency applications.

However, when the test frequencies range from 50 kHz to 1 MHz, the capacitance values of the 865080443007 Capacitor deviate significantly from the statistical benchmark. This indicates that the capacitor may not be optimal for high-frequency applications since the decline in capacitance values could negatively affect performance.

It is essential to highlight that the 865080443007 Capacitor displays higher capacitance values across the entire frequency range when subjected to 10 Volts as opposed to 1 Volt. This suggests that this particular capacitor performs more efficiently in higher voltage applications.

In conclusion, the 865080443007 Capacitor demonstrates satisfactory performance under specific test conditions, making it ideal for certain applications. However, it may not be the optimal choice for continuous high-frequency environments. To find the best-suited component for any specific application, engineers should evaluate other aluminum electrolytic capacitors within the same class and take into account their specific requirements and desired performance outcomes.

Series Resistance

In this section, we're analyzing the series resistance performance of Würth Elektronik's Aluminum Electrolytic Capacitor (part number 865080443007) in relation to a benchmark based on other capacitors with equivalent value. The data provided reveals measurable differences between the component's resistance across various frequencies as compared to the average resistance values from the statistical benchmark.

At lower frequencies—such as 5 Hz and 10 Hz—the 865080443007 Capacitor demonstrates a notably lower resistance compared to the benchmark's average, exhibiting measured resistances of 14.74 Ohms and 7.086 Ohms, respectively. These measurements significantly outperform the benchmark's average values of 44.75 Ohms and 18.59 Ohms for the respective test frequencies. As the frequency increases, the Capacitor maintains its superior performance with lower resistance than the benchmark average across most test frequencies, although still remaining within the minimum-maximum range.

The component displays an impressive resistance reduction when voltage increases from 1V to 10V, especially at lower frequencies (for example: 14.76 Ohms at 10 Hz). Nonetheless, there's a noticeable increase in resistance at higher test frequencies, such as 50 kHz and beyond, in the 10V measurements.

Taking all factors into account, the Würth Elektronik Aluminum Electrolytic Capacitor (part number 865080443007) exhibits an overall better performance concerning series resistance, predominantly at lower frequencies. The capacitor manages to maintain a lower resistance as compared to the benchmark average across most test frequencies when tested at 1 Volt. While the resistance rises at higher test frequencies in the 10 Volts measurements, this information is crucial for electronics engineers as they assess the suitability of this component in their specific applications.

Dissipation Factor and Quality Factor

In this section, we will delve into comparing our component's Dissipation Factor (Df) and Quality Factor (Q) with the respective statistical benchmark data. The results from these evaluations can significantly impact a component's performance and efficiency. LCR (Inductance, Capacitance, and Resistance) measurements help us understand the behavior of the component within specified test frequencies, ranging from 5 Hz to 1 MHz, tested at 1 and 10 Volts. Generally, electrical components, such as capacitors, benefit from having a lower Df and a higher Q.

While testing at 1 Volt, the Df values are in the range of 0.021 or 2.1% (at 5 Hz) to 0.026 or 2.6% (at 50 Hz). This demonstrates that the capacitor is performing well when juxtaposed with the statistical benchmark data. The Q factor inversely ranges from 47.76 at 5 Hz to an impressive 49.98 at 10 Hz. These high Q values contribute significantly to the component's overall optimal performance.

When the test voltage is increased to 10 Volts, there is a slight increase in the Df values, ranging from 0.058 or 5.8% (at 5 Hz) to 0.044 or 4.4% (at 10 Hz). Correspondingly, the Q factor now varies from 16.93 at 5 Hz to a satisfactory 22.79 at 10 Hz. These Q factor values, although lower than those observed at 1 Volt, are still acceptable when compared to the benchmark data.

In conclusion, the component maintains low Df values and moderately high Q factors within the analyzed frequency range. While it is true that the Df values increase at higher test voltages, the component still yields results comparable to the statistical benchmark data. This assessment demonstrates that this particular capacitor is a viable option for engineers seeking components that exhibit stable performance characteristics across various test conditions.

The dissipation and quality factors of the Würth Elektronik 865080443007 capacitor remain competitive in the mid-frequency ranges. However, the capacitor performs significantly poorer compared to the statistical benchmark at the higher frequencies. At 500 kHz, the observed dissipation factor was 3.84 compared to a benchmark of 3.84. Furthermore, at 750 kHz, the capacitor's dissipation factor was 4.92 compared to an average of 9.80 across the benchmark.

Overall, the Würth Elektronik 865080443007 Aluminum Electrolytic Capacitor demonstrates suitable performance capabilities for various low to mid-frequency applications. However, potential users assessing this capacitor for suitability in their circuits should remain cautious in high-frequency applications or where low impedance and resistances are critical. In such cases, alternative options that better match the statistical benchmark may need consideration.
