In this section, we delve into an in-depth analysis of the Series Resistance performance of Holy Stone Enterprise Co., Ltd.'s C0805X475K025T capacitor. Utilizing the LCR measurements provided at 1 Volt and 10 Volts, we meticulously compared the Series Resistance (Ohms) performance of the C0805X475K025T against the provided statistical benchmark data to fully comprehend its versatility and suitability in a variety of circuit designs. At a test frequency of 5Hz, the C0805X475K025T capacitor showcases a considerably lower series resistance (177.7 Ohms at 1V and 282.7 Ohms at 10V) when compared to both the minimum (4.769 Ohms) and the average of the benchmark (252 Ohms). As we observe the frequency increasing, it becomes apparent that the capacitor's series resistance experiences a substantial improvement; for instance, within the 100Hz frequency range, the C0805X475K025T capacitor exhibits a minimal 8.91 Ohms at 1V and 15.02 Ohms at 10V, which is significantly lower than the benchmark average of 13.82 Ohms and only reaches a maximum of 34.16 Ohms. This particular trend is consistent across a wide range of frequencies, which highlights the capacitor's optimal performance for low-frequency applications.

Moreover, when focusing on the 1kHz frequency range, the C0805X475K025T capacitor still outperforms the benchmark, delivering an impressive series resistance value of merely 489.3m Ohms at 1V and 1.149 Ohms at 10V. In comparison, the average benchmark values stand at 1.348 Ohms. This exceptional performance demonstrates that the capacitor can be trusted to uphold a low series resistance, thus providing enhanced performance for circuits necessitating stable impedance at higher test frequencies.

However, it is important to note that the provided LCR measurements for the C0805X475K025T capacitor do not encompass frequencies beyond the 1kHz range. Consequently, further comparisons with the statistical benchmark within the higher frequency spectrum cannot be concluded at this time. Nevertheless, given its dependable performance within the lower frequency range, we encourage engineers to examine the potential applicability of the C0805X475K025T capacitor in their designs. Furthermore, if required by specific applications, it would be prudent to obtain LCR measurements at higher frequencies to ensure this component's absolute suitability.

Dissipation Factor and Quality Factor

In this section, we delve into the capacitor's performance by examining its Dissipation Factor (Df) and Quality Factor (Q) characteristics. A comprehensive understanding of these key performance metrics is crucial for engineers seeking capacitors that minimize energy loss, a critical attribute in various applications, from power electronics to high-frequency circuits.

The examined capacitor manifests fluctuating Df and Q parameters contingent upon the applied test frequency and voltage. By juxtaposing its behavior against a statistical benchmark of capacitors with comparable capacitance values, we can more accurately evaluate the component's performance and predict its suitability in specific situations.

At a low test voltage of 1 Volt, the Df displays variability, ranging between 0.014 and 0.028, with the minimum measurement occurring at the midrange frequency of 1 kHz. Concurrently, the Q values span from 35.74 at the relatively low frequency of 5 Hz to a substantial elevation of 70.22 at 1 kHz. These observations indicate that at lower voltages and frequencies around 1 kHz, this capacitor exhibits relatively low energy losses and higher energy storage capabilities, vital in numerous applications.

When the applied test voltage is elevated to 10 Volts, we observe a marked shift in the Df and Q values. The Df exhibits a more confined range of 0.037 to 0.045, suggesting a higher loss factor at this increased test voltage. Correspondingly, the Q values now fall within a rather narrow range of 22.02 at 100 Hz to 26.97 at 1 kHz. This reduced variability in Q readings signifies consistent energy storage capabilities within the tested frequency range, but also that the capacitor might be less optimal in terms of energy loss at higher voltages.

By analyzing the performance metrics of the capacitor based on its Dissipation Factor (Df) and Quality Factor (Q), we grant engineers valuable insights into its behavior under different test frequencies and voltages. Such information is imperative for designing and optimizing efficient electronic systems and making informed component choices aligned with specific application requirements.
