• Series capacitance values tend to deviate from the benchmark as frequency increases

Bearing these pros and cons in mind, this review will delve deeper into the performance characteristics of the CL31B475KAHNFNE capacitor, while maintaining an impartial, professional, trustworthy, and knowledgeable approach. The comparative analysis will highlight key aspects that may impact the ultimate decision of integrating this capacitor into electronic circuit designs.

Impedance

In the frequency range of 10 Hz to 50 kHz, the impedance of the Samsung Electro-Mechanics Ceramic:X7R capacitor, CL31B475KAHNFNE, generally aligns with the average impedance presented by the benchmark data. At lower frequencies, the impedance is slightly above average, but remains within the expected range for other components with the same capacitance value of 4.7μF. For instance, at 5 Hz, the measured impedance is 6.37k Ohms, which is just above the benchmark average impedance of 6.293k Ohms. At 10 Hz, the impedance registers 3.217k Ohms, slightly higher than the benchmark average impedance of 3.159k Ohms.

When measured from 50 kHz to 1 MHz at 1 Volt, the impedance values deviate somewhat from the statistical averages. For example, at 50 kHz, the impedance is 830.5m Ohms, which is lower than the 878.3m Ohms benchmark. On the other hand, at 75 kHz, the impedance significantly increases to 557m Ohms in comparison to the 619.7m Ohms benchmark. The performance of the capacitor at 10 Volts also reveals mixed results. However, when the impedance value is lower than the statistical benchmark, it can be advantageous for applications that require lower equivalent series resistances.

Throughout the frequency range of 5 Hz to 100 kHz, the Samsung Electro-Mechanics Ceramic:X7R capacitor, CL31B475KAHNFNE, exhibits performance that is largely consistent with the provided statistical benchmark data. This overall consistency suggests that the component could be a reliable choice for engineers looking for a capacitor with a predictable performance across an extensive frequency range. Nevertheless, applications focusing on specific impedance values at higher frequencies may warrant additional consideration and analysis due to the component's varying performance when compared to the benchmark data.

Capacitance

In this section, we will be evaluating the capacitance performance of the component by examining its LCR measurements at two voltage levels: 1 Volt and 10 Volts. A thorough analysis of the series capacitance at different test frequencies is important as it affects the overall functionality and efficiency of electronic circuits in various applications.

Upon analyzing the given LCR measurements at 1 Volt, the component’s series capacitance remains within the 10% tolerance range up to 1M test frequency. It's worth noting that the series capacitance deviates from the average benchmark between test frequencies of 1k to 1M. The CL31B475KAHNFNE shows a lower series capacitance compared to the benchmark's average. For instance, the difference at 1M is substantial, with a series capacitance of 4.949μ compared to the benchmark's 4.623μ. This deviation might contribute to differences in circuit response, depending on the specific application.

Now, let's evaluate the capacitance values when the measurements are taken at 10 Volts. The capacitance of the CL31B475KAHNFNE again falls within the 10% tolerance range at most test frequencies. However, the component exhibits an increased deviation from the statistical benchmark, especially within the 50k to 600k frequency range compared to the 1 Volt test. For example, at a 600k test frequency, the CL31B475KAHNFNE's series capacitance is 4.465μ compared to the benchmark's 27.72μ, a considerably lower value. This indicates that the deviation between the component and the benchmark's average becomes more significant as the test voltage is increased. Therefore, it is essential to consider these deviations when selecting a capacitor for use in high voltage situations.

In conclusion, the capacitance performance of the CL31B475KAHNFNE varies depending on the test voltage and frequency. Understanding the importance of these deviations allows engineers to make informed decisions when selecting components for their specific applications, ensuring optimal circuit performance and efficiency.

Series Resistance

The CL31B475KAHNFNE Capacitor was thoroughly analysed for its Equivalent Series Resistance (ESR) performance against the provided statistical benchmark data. The comprehensive examination was conducted at two voltage levels (1V and 10V) over a range of test frequencies, to assess its consistent performance in varied conditions.

At a voltage level of 1V, the capacitor displayed relatively lower ESR values over most of the test frequencies. Notably, it outperformed the benchmark average at 50 Hz (30.83 Ohms vs 27.59 Ohms), 100 Hz (15.95 Ohms vs 13.82 Ohms), and showed a significant improvement at 500 Hz (2.94 Ohms vs 2.885 Ohms). These findings highlight the superior performance of the CL31B475KAHNFNE capacitor at these specific frequencies. However, at other frequencies above 1 kHz, the ESR was consistently lower than the statistical average, indicating even better performance.

Similar performance trends were observed at a higher voltage level of 10V. The capacitor exhibited lower ESR values at most test frequencies, outperforming the benchmark average substantially at 50 Hz (34.39 Ohms vs 27.59 Ohms) and 100 Hz (17.99 Ohms vs 13.82 Ohms). At higher frequencies above 1 kHz, the capacitor continued to demonstrate its superior performance, with consistently lower series resistance values. This observation further underscores the component's reliability and consistency over a wider range of test frequencies.

Overall, the CL31B475KAHNFNE Capacitor exhibits favorable ESR performance as compared to the statistical benchmark data. However, its performance at lower test frequencies, such as 50 Hz and 100 Hz, could be enhanced further. Engineers considering this capacitor for their application circuits can expect relatively lower ESR values at most test frequencies compared to other capacitors in the market, with particularly impressive performance at frequencies above 1 kHz. This knowledge can help in selecting components with optimal performance for specific application requirements, ensuring efficient and effective final designs.

Dissipation Factor and Quality Factor

The performance of the CL31B475KAHNFNE capacitor in terms of Dissipation Factor (DF) and Quality Factor (Q) was analyzed against a statistical benchmark consisting of data from other capacitors with a similar value.

In tests conducted at 1 volt, the capacitor's performance was observed to be optimal at test frequencies within the lower range. At 5kHz, 10kHz, and 20kHz, this capacitor outperformed the average dissipation factors with values of 0.019, 0.016, and 0.016, respectively. These values are significantly lower than the corresponding average dissipation factors of 0.04, 0.05, and 0.09. Moreover, the Quality Factor for this capacitor at these frequency ranges performed exceptionally well, with notably higher values of 52.85, 60.69, and 62.07 as compared to the average Q values (82.09, 94.55, and 55.65).

However, a decline in performance was observed as the test frequency increased, particularly beyond 100kHz. For instance, at 500kHz, the DF reaches a high of 0.054, while the benchmark's average is 0.89. This measurement indicates a decrease in efficiency, and the Quality Factor follows suit, registering a value of 18.46 as opposed to the average Q value of 8.46.

During the performance analysis at 10 volts, an interesting trend was observed. At the test frequency of 100kHz, the capacitor exhibited a remarkable improvement in Quality Factor with a value of 3897.07, which substantially surpasses the average Q (27.82) and maximum Q (67.99) displayed by the benchmark data. This spike in performance at higher voltages demonstrates the capacitor's adaptability and stability under various operating conditions.

It is essential to consider these observations when evaluating the CL31B475KAHNFNE for specific applications. While the component performs best at low frequency ranges under a 1-volt input, the performance tends to deteriorate as the frequency increases. Nevertheless, the impressive Quality Factor achieved at high voltages illustrates that this capacitor has the potential to perform effectively under diverse conditions, making it a valuable component in many applications.
