This evaluation provides a comprehensive review, highlighting the pros and cons of this specific capacitor and offering valuable insights to determine if it meets the expectations set by its statistical benchmark data.

The component in question is a Ceramic (X5R), Surface Mount capacitor with a nominal value of 47μF and a tolerance of ±20%. Its voltage rating is 10 volts, and it features a package size of 1206 (3216 Metric). The CL31A476MPHNNNE has been tested at both 1 Volt and 10 Volts, measuring various parameters across different test frequencies. Use this technical review to make an informed decision on whether the Samsung CL31A476MPHNNNE Capacitor is suitable for your specific project requirements.

• Pros:
  • Resilient series resistance values over a wide range of frequencies
  • Improves quality factor as the test frequency increases
  • Exhibits relatively low dissipation factors at lower test frequencies
• Cons:
  • Capacitance values may not perform as well compared to benchmark data at specific test frequencies

  • Quality factor tends to deteriorate at test frequencies over 400kHz

Impedance

Upon examining the impedance characteristics of the CL31A476MPHNNNE and comparing its values to the statistical benchmark data, we find that the capacitor's impedance performance is reasonably close to the average across most test frequencies. For instance, at a test frequency of 10Hz, the component's impedance at 1V is 375.8 ohms, which is marginally more elevated than the benchmark average of 332.8 ohms. Furthermore, at 100Hz, it exhibits an impedance of 42.69 ohms, somewhat higher than the average impedance of 35.87 ohms at this frequency. Interestingly, it surpasses the statistical benchmark's maximum impedance at 50Hz, achieving 80.12 ohms as opposed to 69.54 ohms.

When evaluating the capacitor's performance under a higher voltage level of 10V, we observe that the impedance values tend to show an upward trend, especially at lower frequencies, in comparison to those measured at 1V. For example, at 5Hz, the CL31A476MPHNNNE capacitor exhibits an impedance of 1.299k ohms, whereas it registers a value of only 747 ohms at 1V. On the other hand, the impedance tends to stabilize at higher test frequencies, such as 950kHz and above, as evident from the values of 37.99m ohms and 38.1m ohms at 1V and 10V, respectively.

In summary, the Samsung Electro-Mechanics' CL31A476MPHNNNE capacitor demonstrates impedance performance that is largely consistent with the benchmark averages across various test frequencies. However, it is essential to note the distinct fluctuations observed at certain points within the frequency range. When evaluating the suitability of this capacitor for specific circuit applications, it is crucial to consider its impedance performance relative to the benchmark data and its potential impact on overall circuit performance.

Capacitance

When analyzing the CL31A476MPHNNNE's series capacitance, we can observe its performance over a wide range of test frequencies from 5Hz to 1MHz. At lower test frequencies (5Hz to 500Hz), the capacitance values are generally higher and closer to the nominal value of 47µF when compared to the statistical benchmark data. This performance may be due to the characteristics of the dielectric material and the construction of the capacitor.

However, as the test frequencies increase from 1kHz and above, the capacitance values of the CL31A476MPHNNNE capacitor decrease significantly, deviating from the benchmark data. This trend is common among capacitors as their reactance tends to decrease with increasing frequency, which in turn affects the capacitance values.

For instance, at 50kHz, the CL31A476MPHNNNE's series capacitance value is measured at 26.84µF, whereas the statistical benchmark states an average value of 31.64µF. Similarly, at 700kHz, the capacitance drops to 200µF, while the statistical benchmark indicates an average value of 1.456mF. This demonstrates that the capacitor's performance is inconsistent at higher frequencies compared to other components with the same nominal value.

One particularly significant deviation occurs at 750kHz, where the CL31A476MPHNNNE capacitor's capacitance value reaches 50.78mF, compared to the benchmark average value of 6.611mF. This disparity highlights the substantial difference in performance at this frequency.

While the CL31A476MPHNNNE capacitor performs well and yields capacitance values closer to the nominal value at lower test frequencies, the considerable deviation from the statistical benchmark data observed at higher test frequencies limits its suitability for applications that demand consistent performance over an extensive frequency range. Accordingly, engineers should carefully consider the capacitance behavior and its potential impact on the selected circuit or application while evaluating the suitability of this capacitor for their designs.

Series Resistance

In our analysis of the CL31A476MPHNNNE component data, we observe that the series resistance performance presents an appreciable outcome across a wide range of test frequencies when benchmarked at 1 Volt. Notably, at lower test frequencies (5 Hz and 10 Hz), there is a tendency for higher series resistance values to be observed. For instance, at 5 Hz, the CL31A476MPHNNNE displays a series resistance of 49.65 Ohms, which is slightly higher than the average benchmark value of 44.75 Ohms. Similarly, at 10 Hz, it records a value of 25.39 Ohms, which is again higher than the average benchmark of 18.59 Ohms. However, as the test frequency escalates, the series resistance values for the CL31A476MPHNNNE come into closer alignment with the benchmark averages, particularly within the 100 Hz to 1 MHz range.

At 10 Volts, a parallel trend is observed in the series resistance performance of the CL31A476MPHNNNE, with elevated values detected at lower test frequencies (5 and 10 Hz). Yet, the capacitor's series resistance values become increasingly convergent with - or even superior to - the benchmark data, as manifested in the middle-to-high frequency scope (spanning from 50 Hz up to 1 MHz).

Despite lying modestly above the benchmark averages at lower test frequencies, the series resistance performance of the Samsung Electro-Mechanics CL31A476MPHNNNE reveals its competitive nature at higher frequencies. This evaluation confirms its appropriateness for diverse applications requiring stable ESR performance within the Ceramic: X5R capacitors domain. Consequently, engineers can rely on the CL31A476MPHNNNE as a dependable option for both analog and digital circuits operating at various frequencies, ensuring efficient performance and durability.

Dissipation Factor and Quality Factor

When evaluating the performance of Samsung Electro-Mechanics' CL31A476MPHNNNE capacitor, it becomes critical to examine the dissipation factor (Df) and quality factor (Q) concerning statistical benchmark data. Gaining insight into the component's Df and Q is essential for electronic engineers considering integrating this capacitor into their designs.

First, let's delve into the dissipation factor, which is the ratio of real power to reactive power in an electrical component. Ideally, it should be as low as possible for optimal performance. The LCR measurements, taken at 1 Volt, reveal a Df that fluctuates from 0.067 at 5 Hz to 5.516 at 500 kHz. As the test frequency increases, the Df generally tends to follow an increasing trend, with notable exceptions at 100 Hz (0.065) and 1 kHz (0.036), indicating better performance at these frequencies.

Performing the LCR measurements at 10 Volts, we observe a similar trend in the Df values, with a few data points even outperforming the measurements obtained at 1 Volt. On the other hand, at higher frequencies (450 kHz to 1 MHz), there is a lack of Df measurements, rendering a comprehensive comparison impossible.

Moving on to the quality factor (Q), which represents the efficiency of an electrical component and should ideally be maximized, the LCR measurements taken at 1 Volt show a Q range from 15.01 at 5 Hz to 0.10 at 600 kHz. Interestingly, the Q values demonstrate an inverse correlation with the Df measurements, displaying a decreasing tendency as frequencies rise, with some minor exceptions. The quality factor at 500 kHz is 0.18, which is considerably lower compared to the lower frequency Q values, such as 27.47 at 1 kHz and 23.71 at 500 Hz.

Similar to the Df measurements, the LCR measurements for Q at 10 Volts follow the trend observed at 1 Volt, with some comparative improvements. However, the Q values are missing for higher frequencies (600 kHz to 1 MHz), which once again prevents a complete analysis. This gap in data emphasizes the importance of acquiring a complete set of measurements to fully understand the performance of the CL31A476MPHNNNE capacitor over the entire frequency range.

Comparative Analysis

Conclusion

In summary, the Samsung Electro-Mechanics CL31A476MPHNNNE surface mount ceramic capacitor (X5R) exhibits a mix of both commendable and subpar performance characteristics when compared to the statistical benchmark data. To begin with, this 47μF capacitor exceeds the benchmark by offering impressive capabilities in the lower frequency range such as 5Hz to 50Hz, making it suitable for applications that demand good performance at lower frequencies.

However, when examining higher frequency data, particularly beyond 100kHz, the CL31A476MPHNNNE capacitor's performance is less noteworthy. Specifically, the Impedance, Dissipation Factor, and Quality Factor underperform the statistical benchmark, signaling room for improvement in these areas, especially within the 100kHz to 1MHz range.

Additionally, it is worth noting that the CL31A476MPHNNNE capacitor exhibits a progressive drop in Series Capacitance and a noticeable rise in Series Resistance as the frequency increases. These tendencies could impact specific use cases crucial to some electronics engineers and should be considered when evaluating this component for application in high-frequency situations.

Overall, while the CL31A476MPHNNNE capacitor from Samsung Electro-Mechanics demonstrates strong performance in certain areas, it falls short in others, particularly when it comes to higher frequency applications. Electronics engineers should carefully consider the specific requirements of their projects before choosing to incorporate this capacitor into their designs.
