Impedance

The WIMA MKS2B044701K00KSC9 Capacitor demonstrates a performance that is closely on par with the statistical benchmarks when analyzed in terms of impedance. By comparing the component's data with selected components of the same value, we can observe tight correlations between the MKS2B044701K00KSC9's impedance measurements and the benchmark averages at various voltage and frequency levels.

At 1 Volt, the WIMA MKS2B044701K00KSC9 Capacitor's impedance measurements closely align with the benchmarks. In the lower frequency range (e.g., 5 kHz), the capacitor performs slightly better, with a measured impedance of 6.87 Ohms compared to the 7.722 Ohms benchmark average. However, in the higher frequency range (e.g., 700 kHz), the component's performance tends to reside towards the upper end of the benchmark boundaries, with a 49.49m Ohm measurement, while the benchmark average sits at 12.66m Ohms.

For the LCR measurements at 10 Volts, there is a lack of data for frequencies above 100 kHz. Nevertheless, the available data exhibits similar trends to the 1 Volt results. The MKS2B044701K00KSC9 Capacitor performs in close proximity to the benchmark averages. For example, at 50 kHz, its measured impedance is 687.2 mOhms, while the benchmark average is 878.3 mOhms.

While additional test data from the remaining frequencies above 100 kHz would be needed for a more comprehensive analysis, the existing impedance measurements provide valuable insights into the capacitor's performance. These findings suggest that the WIMA MKS2B044701K00KSC9 Capacitor exhibits relatively consistent performance when analyzing impedance, making it a reliable choice for various electronic applications that require stable capacitance values across different frequency ranges.

Capacitance

The WIMA MKS2B044701K00KSC9 film capacitor, composed of a Film: Polyester, Polyethylene Terephthalate (PET), Metallized construction, displayed a series capacitance of 4.681μF at 1V and 5Hz. This value is marginally below the average of 5.107μF for the statistical benchmark data collected under the same testing conditions. It's worth noting that the capacitor's capacitance consistently remained within 10% of its nominal value of 4.7μF, with only the benchmark average marginally exceeding the nominal value across a wide range of test frequencies.

Upon close examination of the component's performance at 1V, the series capacitance reached its peak at 4.782μF. However, a significant increase in capacitance was observed at higher frequencies, culminating at 86.57μF at 700kHz—well beyond the nominal value. Despite this discrepancy at such high frequencies, capacitance values below 150kHz consistently fell within the tolerance range, making the component an acceptable choice for applications with lower frequency requirements.

Similar performance trends were observed when testing the MKS2B044701K00KSC9 capacitor at 10V. Like the 1V test, capacitance values remained below the statistical benchmark average, and the trend of increasing capacitance at higher frequencies persisted.

Significantly, the WIMA MKS2B044701K00KSC9 capacitor outperformed the statistical benchmark at 50kHz, falling just 0.002μF short of the average in both 1V and 10V tests. While the benchmark trend indicated a decrease in capacitance at this frequency, the capacitor maintained a stable performance. This consistency highlights the superior performance of the capacitor's Film: Polyester, Polyethylene Terephthalate (PET), Metallized composition within this category and suggests that it's a reliable choice for applications requiring stable capacitance values at 50kHz.

In conclusion, the WIMA MKS2B044701K00KSC9 capacitor delivers its best performance within lower frequency ranges, up to 50kHz, where its capacitance values remain relatively stable and mostly within its tolerance range. Engineers evaluating this capacitor for their applications should carefully consider its dependable performance within the specified frequency range to ensure optimal results.

Series Resistance

When analyzing the series resistance of the MKS2B044701K00KSC9 Capacitor, we'll examine its performance at different frequencies and input voltage levels. Series resistance, also referred to as equivalent series resistance (ESR), is a crucial parameter for capacitor performance, impacting factors such as power dissipation, circuit efficiency, and operating temperature.

At a low frequency of 5 Hz and an input voltage of 1 volt, the MKS2B044701K00KSC9 Capacitor demonstrates a series resistance of 10.03 Ohms. Comparing this value with the statistical benchmark of 252 Ohms at the same frequency, it is evident that the WIMA Capacitor performs with significantly lower resistance at low frequencies.

Moving to a higher frequency of 50 kHz, the MKS2B044701K00KSC9 Capacitor's series resistance reduces to 28.02 milli-ohms. Comparatively, at the same frequency, the statistical benchmark reports an average resistance of 149.9 milli-ohms. The WIMA Capacitor continues to display superior performance, maintaining a notably lower resistance compared to the average benchmark.

While the gap between the MKS2B044701K00KSC9 Capacitor and the benchmark narrows as the frequency increases, the component's resistance remains lower than the average throughout the tested range. This observation suggests a superior yet more comparable performance at higher frequencies.

Furthermore, when the input voltage is increased to 10 volts at 50 kHz, the series resistance for the MKS2B044701K00KSC9 Capacitor drops to 17.51 milli-ohms. This reduction in resistance with increased input voltage hints at the capacitor's ability to adapt to varying input conditions and maintain high-performance. In summary, the WIMA MKS2B044701K00KSC9 Capacitor demonstrates consistently superior series resistance compared to the statistical benchmark data across a range of frequencies and input voltage levels.

Dissipation Factor and Quality Factor

The Dissipation Factor (Df) and Quality Factor (Q) of the WIMA MKS2B044701K00KSC9 Capacitor play a crucial role in determining its performance characteristics, particularly its efficiency and suitability for varying frequency applications. In this section, we discuss the behavior of these factors across different voltage and frequency conditions.

At a test voltage of 1 Volt, the Df of the WIMA MKS2B044701K00KSC9 Capacitor remains quite low for a significant portion of the test frequency spectrum, at or below 0.001 for frequencies of 10 Hz and 50 Hz. This suggests good energy efficiency in low-frequency applications. However, as the test frequency increases, the Df value also rises, reaching up to 1.420 at 500 kHz and 5.650 at 650 kHz, indicating diminished efficiency at higher frequencies.

Correspondingly, at the same test voltage, the capacitor demonstrates high Quality Factor values at low test frequencies, such as 669.61 at 5 Hz and 1075.35 at 10 Hz. These values indicate low losses and high resonant capabilities at lower frequencies. However, the Quality Factor decreases significantly as the test frequency rises, reaching values as low as 1.28 at 400 kHz and 0.44 at 1 MHz, suggesting less suitability for high-frequency applications.

When the test voltage is increased to 10 Volts, the initial Df measurements at low frequencies like 5 Hz and 10 Hz remain very low, at 0.001 and 0.000 respectively, maintaining energy efficiency. In contrast, the Q values rise considerably and are recorded as 779.44 and 3280.98 at these frequencies, further emphasizing the capacitor's performance in low-frequency applications. At higher test frequencies such as 50 kHz and 100 kHz, the Df increases to 0.025 and 0.051, whereas the Q decreases to 39.30 and 19.64, respectively. This again demonstrates that the WIMA MKS2B044701K00KSC9 Capacitor predominantly exhibits performance characteristics more suitable for low-frequency applications.
