Introduction

The Würth Elektronik Capacitor (part number 860020472006) is an Aluminum Electrolytic capacitor suitable for through-hole mounting with a radial, can package. This thorough review will analyze the performance of this capacitor in comparison to the benchmark data provided. When it comes down to the performance of a capacitor, measurements such as impedance, dissipation factor, quality factor, series resistance, and series capacitance at varying test frequencies and voltages are crucial in determining its applicability within an engineer's circuit design.

Pros:

• Low impedance at higher frequencies
• Stable quality factor at low frequencies
• Wide range of test frequencies
• Manufactured by a reputable company with extensive experience in capacitors and other electronic components

Cons:

• High dissipation factor at higher test frequencies
• Lower quality factor at higher frequencies compared to benchmark
• Inconsistent series resistance and capacitance across the frequencies tested

Impedance

Upon a thorough examination of the LCR (inductance, capacitance, and resistance) measurements at an applied voltage of 1 Volt, it becomes apparent that the capacitor's impedance values tend to be higher than the average benchmark impedance values throughout the entire frequency range. For instance, at a test frequency of 5 Hz, the impedance value recorded was 668.5 Ohms, which is slightly above the average value of 656.9 Ohms. Another noteworthy difference is observed at the 50 Hz frequency, where the impedance value stands at 70.08 Ohms, compared to the average benchmark value of 69.54 Ohms. At a much higher frequency of 100 kHz, the capacitor exhibits an impedance value of 887.1m Ohms - almost three times higher than the benchmark average of 319.4m Ohms.

Moving on to the LCR measurements at a higher testing voltage of 10 Volts, the impedance values of the capacitor maintain a relatively consistent trend of surpassing the average benchmark values. The performance at a low 5 Hz frequency, with an impedance value of 639.8 Ohms, calls for a cautious assessment of this component. Furthermore, the 100 kHz measurement unveils an impedance value of 1.125 Ohms, which is noticeably higher than the expected benchmark data.

Upon careful scrutiny, these observations indicate that while the capacitor has acceptable impedance levels in lower frequency ranges, it presents significantly increased values at higher frequencies. This is crucial information for engineers, as they should exercise discretion when evaluating this capacitor for their circuit designs, considering that it may not always meet the desired performance requirements, particularly for applications that require high-frequency operation. A sound comprehension of impedance values' implications on a component's suitability in various applications is critical for making informed decisions while designing and optimizing electronic circuits.

Capacitance

In this section, the capacitance behavior of the Würth Elektronik 860020472006 Aluminum Electrolytic Capacitor across different test frequencies in LCR (Inductance, Capacitance, and Resistance) measurements will be analyzed and compared to a statistical benchmark formed from other components possessing the same nominal capacitance value of 47μF. The capacitor's performance at both 1 and 10 Volts will be investigated, providing valuable insights regarding its suitability for various applications.

At 1 Volt, the capacitor's series capacitance demonstrates commendable performance at low frequencies. It surpasses the average series capacitance of the statistical benchmark across the frequency range of 5 Hz to 1 kHz and maintains a consistent capacitance range of 40.39μF to 47.54μF. This indicates a stable and trustworthy performance compared to other capacitors, which may exhibit larger fluctuations in capacitance within the mentioned frequency domain.

On the other hand, as the test frequency rises above 1 kHz, the capacitor's capacitance experiences a decline, falling below the statistical benchmark average. Specifically, the capacitance value descends to as low as 7.435μF at 550 kHz. However, when tested at even higher frequencies between 650 kHz to 1 MHz, the capacitance value recovers to 15.15μF.

When 10 Volts are applied, the capacitor presents slightly improved overall capacitance values, particularly in low to mid-range frequencies (5 Hz to 1 kHz). Similar to the 1 Volt scenario, capacitance values plunge beneath the benchmark average when the test frequency exceeds 1 kHz, with the lowest value being 5.903μF at 550 kHz. The capacitance then displays an improvement at elevated test frequencies before reaching 1 MHz.

Ultimately, the Würth Elektronik 860020472006 Aluminum Electrolytic Capacitor exhibits notable performance within low to mid-range frequencies, rendering it a competitive choice for capacitors with the same nominal 47μF value. Nonetheless, its decreased series capacitance in higher frequency ranges must be taken into account when assessing its suitability for specific applications or projects.

Series Resistance

Upon scrutinizing the LCR measurements at 1 Volt, it is evident that the Aluminum Electrolytic 860020472006 Capacitor exhibits a unique pattern for its series resistance across test frequencies. In comparison to average benchmark values, the Capacitor's series resistance at lower test frequencies (such as 5Hz and 10Hz) is indeed lower. For instance, at 5Hz, the measured series resistance stands at 17.44 Ohms, a significant difference from the average value of 44.75 Ohms. Similarly, at 10Hz, the series resistance is recorded at 10.33 Ohms, while the average benchmark is 18.59 Ohms.

However, an interesting observation arises when analyzing the 50Hz frequency, where the Capacitor's series resistance slightly exceeds the benchmark, amounting to 4.673 Ohms against the average value of 3.037 Ohms.

As we progress to higher test frequencies, the Aluminum Electrolytic 860020472006 Capacitor predominantly showcases a higher series resistance compared to the statistical benchmark average values. For example, at 250KHz, the measured series resistance is 835.1m Ohms, considerably higher than the benchmark value of 287.9m Ohms. This trend is consistent across most higher test frequencies; however, this divergence might still be acceptable depending on specific engineering requirements.

Evaluating the LCR measurements at 10 Volts reveals a similar pattern of performance, where the Capacitor's series resistance is lower than the statistical benchmark values for the lower test frequencies. Conversely, for the majority of higher test frequencies, the series resistance values surpass the benchmark averages. These comparisons are made while considering the tolerance limits of the component. Furthermore, this distinct trend continues until the available dataset reaches its maximum limit at 1 MHz, highlighting the importance of understanding component behavior across different frequencies and engineering conditions in order to optimize its utilization.

Dissipation Factor and Quality Factor

The Dissipation Factor (Df) and Quality Factor (Q) are crucial parameters in evaluating the performance of the 860020472006 component, especially in terms of energy dissipation and resonance magnification. Comparing these factors to statistical benchmarks at various frequencies, we can assess the component's suitability for different applications.

When examining the data at a test frequency of 5 kHz, the 860020472006 has a Df of 0.026 and a Q value of 38.15 at 1 Volt, demonstrating strong performance in low-frequency regions. Similarly, at 10 kHz, the component exhibits a Df of 0.031 and a Q of 32.67. These results indicate that the 860020472006 is adept at handling energy loss and maintaining good resonant behavior at lower frequencies.

However, as the frequency levels increase, we notice that the performance begins to decline, with increasing Df values and decreasing Q values. This trend may affect the component's overall effectiveness at higher frequencies. For example, at 10 kHz using 10 Volts, the Df value is 2.107, and the Q value drops significantly to 0.47, which is considerably below the optimal performance range required for certain high-frequency applications.

In conclusion, the 860020472006 is well-suited for specific low-frequency applications, as evidenced by the low Df and high Q values found at lower test frequencies. Nonetheless, engineers should be mindful of the component's performance deterioration at higher frequencies as the Df values increase and Q values decrease, potentially impacting the suitability for certain use cases. Making an informed decision on the component's appropriateness for a specific application necessitates a comprehensive understanding of its intended purpose and a thorough analysis of the complete set of test data available.
