In the following sections, we will provide a detailed analysis of the Walsin Technology Corporation Capacitor 0402B104K100CT's performance on various parameters and compare its overall usability to the statistical benchmark data.

Impedance

The 0402B104K100CT exhibits a slightly lower impedance across most tested frequencies when compared to the average impedance of its counterparts in the statistical benchmark. For instance, at 10 kHz, the impedance of the 0402B104K100CT is measured at 159.3 Ohms, while the corresponding average impedance of the benchmark capacitors stands at 164.5 Ohms. This finding suggests that the 0402B104K100CT provides relatively lower impedance, which is advantageous to minimize losses in circuits and enhance efficiency.

When tested at a higher voltage of 10 Volts, the 0402B104K100CT continues to demonstrate a relatively lower impedance compared to the accumulated benchmark data. For instance, at 50 kHz, the impedance of the 0402B104K100CT is recorded at 29.43 Ohms against the statistical average of 34.91 Ohms. Such results validate that the Walsin Technology Corporation's 0402B104K100CT capacitor offers superior impedance performance across the majority of tested frequencies when compared to other Ceramic: X7R components.

It is crucial to understand that this evaluation is based on the impedance characteristics of the 0402B104K100CT capacitor under the specified test conditions. Therefore, the component's actual performance in specific applications might deviate depending on factors such as operating temperature, voltage stress, and frequency response. However, bearing in mind the data available, the 0402B104K100CT capacitor demonstrates a noticeable advantage over its Ceramic: X7R peers in the impedance domain, most likely leading to better overall circuit performance.

Capacitance

The Walsin 0402B104K100CT exhibits a capacitance of 103.9nF at a test frequency of 5Hz, which is slightly higher than the average capacitance value of the benchmark at 101.8nF. This trend continues across various test frequencies, with the Walsin component consistently showing higher capacitance values when compared to the average values from the statistical benchmark. This characteristic can be a potential advantage in certain applications requiring capacitors with slightly elevated capacitance levels, as long as the tolerance is considered acceptable.

At a test frequency of 100kHz, the 0402B104K100CT capacitor has a capacitance of 93.72nF, whereas the average value from the benchmark is found to be 88.4nF. Similarly, at a test frequency of 1MHz, the capacitance of the Walsin capacitor is 88.42nF, as opposed to the benchmark's 82.53nF average capacitance. It is noteworthy that the capacitance values decrease as the frequency increases, which is a typical behavior for capacitors.

When operating at higher voltages, such as 10 Volts, the 0402B104K100CT's capacitance values experience a noteworthy increase across the tested frequencies. At 5Hz, for example, the capacitance rises to 111.8nF. The same tendency is observed in other frequencies, such as 100kHz, where the capacitance attains 103.2nF. The variation in capacitance with voltage is a common characteristic among capacitors; however, designers need to carefully consider this aspect during the component selection process, especially in applications with varying voltage levels or high voltage requirements.

Series Resistance

The Series Resistance (SR) performance of the Walsin 0402B104K100CT capacitor was found to be close to the statistical benchmark at a test voltage of 1V. At frequencies of 5kHz and 10kHz, the SR was marginally below the benchmark average, which may indicate slightly better performance in terms of power dissipation and voltage drop. Conversely, at test frequencies of 500Hz, 1kHz, and 300kHz, the SR exceeded the statistical benchmark averages. This result showcases the capacitor's strong performance at these frequencies, where a higher series resistance is beneficial for suppressing electromagnetic interference (EMI) and improving voltage regulation.

When subjected to a test voltage of 10V, the 0402B104K100CT capacitor demonstrated praiseworthy SR performance. At frequencies of 5kHz, 10kHz, and 20kHz, its SR values were lower than the statistical benchmark average, implying lower power losses and a potentially more efficient operation. On the other hand, at test frequencies of 50kHz, 75kHz, and 100kHz, the capacitor outshined the benchmark, with SR values notably below the averages. This finding emphasizes the capacitor's excellent low-loss characteristics at these frequencies, which can contribute to better circuit performance and energy efficiency.

In conclusion, the Walsin 0402B104K100CT capacitor's Series Resistance performance frequently outperforms the statistical benchmark in certain regions and remains slightly below average in others. However, it is essential to take into account the missing data points between 400kHz and 1MHz for a comprehensive understanding of its performance across the entire frequency range. This information is vital for engineers striving to optimize circuit design and select suitable components based on application requirements.

Dissipation Factor and Quality Factor

In this section, we will be examining the Walsin Technology Corporation's 0402B104K100CT capacitor's performance in terms of the dissipation factor (Df) and quality factor (Q). Both of these parameters are crucial when selecting capacitors for high-frequency applications or circuits where energy conservation and minimal power loss are essential.

Upon conducting measurements at 1 Volt, the 0402B104K100CT capacitor demonstrated a notably low dissipation factor (Df) compared to the statistical benchmarks collected for capacitors of the same value. The minimum Df of merely 0.002 was observed at 300 kHz. As for the quality factor (Q), it was found to increase significantly with the increment in frequency, this reached its peak value of 497.00 at 300 kHz. This indicates that the capacitor is proficient in high-frequency applications and could be a fitting choice.

When subjected to further testing at 10 Volts, the 0402B104K100CT capacitor maintained a relatively low dissipation factor in comparison to the benchmark data. The lowest Df of 0.001 was recorded at 500 kHz. Moreover, the quality factor displayed a similar favorable upward trend as the one observed at 1 Volt. The capacitor achieved an impressive Q value of 1223.60 at 500 kHz, further confirming its suitability for high-frequency circuits and exhibiting its capability as a reliable component in energy conservation applications.

It is pertinent to mention that the dissipation factor and quality factor are inversely proportional to one another. A low dissipation factor signifies a minimal loss of power in the form of heat, while a high quality factor indicates a capacitor's ability to store and release energy with minimal losses. In the case of the 0402B104K100CT, its low dissipation factor and high quality factor have demonstrated the capacitor's effectiveness in both energy conservation and high-frequency applications.

Comparative Analysis

Conclusion

After a thorough analysis of Walsin Technology Corporation's 0402B104K100CT Capacitor, it is clear that the component possesses similar or better characteristics than the average statistical benchmark in certain aspects.

For instance, when voltage is set at 1 Volt, the 0402B104K100CT demonstrates a lower average impedance when compared to the statistical benchmark. Maintaining this difference across several test frequencies, the Capacitor especially outperforms the benchmark in Impedance in the higher frequency range (50kHz and above). However, the lower frequencies show fewer deviations from the benchmark values.

Concerning the Dissipation Factor, the 0402B104K100CT's value is noticeably lower at higher test frequencies (200kHz and above) when voltage is set to 10 Volts. This improvement indicates that the Capacitor has higher efficiency and a lower energy loss in these specific conditions. In other frequency ranges, the Dissipation Factor values remain comparable to the benchmark data.

However, when Capacitance is considered, the Capacitor's performance is not as impressive, staying close to the benchmark data across the entire frequency range. This leaves minimal room for improvement when comparing it to the average statistical benchmark.

In conclusion, the Walsin Technology Corporation's 0402B104K100CT Capacitor showcases a commendable performance when Impedance and Dissipation Factor are evaluated. Nevertheless, electronic engineers should weigh the importance of these factors depending on their application requirements before deciding if this Capacitor will be the optimal choice for their designs.
