Impedance

In this comprehensive analysis of the Samsung Electro-Mechanics CL31B475KAHNNWE, we will assess its impedance performance compared to the statistical benchmark data for capacitors of the same value, providing a well-rounded understanding of its capabilities. Measurements discussed include those taken at 1 Volt and 10 Volts, allowing for an in-depth examination of its performance in a variety of scenarios and catering to diverse application requirements.

The LCR measurements reveal that at a frequency of 5 Hz, the impedance of the Samsung Electro-Mechanics CL31B475KAHNNWE stands at 6.476k Ohms for a test voltage of 1V, somewhat higher than the average impedance measured at 6.293k Ohms. It is essential to consider these deviations when selecting capacitors for specific applications to ensure optimal performance. With an increase in frequency, the impedance follows a downward trend, measuring 399.9m Ohms at 100 kHz, marginally below the benchmark average of 492m Ohms.

This resemblance in impedance performance can be observed at other test frequencies such as 10 kHz, and 50 kHz, with values of 3.169k Ohms and 810.7m Ohms recorded at 10V, respectively. The capacitor remains within a reasonable range of the benchmark values for frequencies up to 100 kHz, before a discernable difference emerges as the frequency exceeds this value.

The Samsung Electro-Mechanics CL31B475KAHNNWE demonstrates consistent impedance performance when compared to the statistical benchmark, particularly when operating at test frequencies up to 100 kHz. Though its performance deviates from the benchmark at higher frequencies, it performs admirably across the test voltages used in the LCR measurements. Owing to its stability at various test voltages and frequencies, this capacitor could be an ideal candidate for engineers working with applications that require a capacitor with a nominal value of 4.7μF operating within the tested ranges. However, as with all capacitors, end-users must always consider specific application requirements and provide appropriate margin when selecting components to ensure the best possible outcome.

Capacitance

When examining the capacitance characteristics of the Samsung CL31B475KAHNNWE capacitor, it is important to consider the measurements taken across various frequencies and voltages. At 1 Volt, the series capacitance of the Samsung capacitor initially starts a bit lower than the average benchmark values at lower frequencies, on average around 4-5% less. To illustrate this, at a frequency of 5Hz, the Samsung capacitor has a capacitance of 4.917μF, while the average benchmark value stands at 5.107μF.

As the test frequency increases, the capacitance of the CL31B475KAHNNWE decreases, and the gap between the component data and the benchmark average narrows significantly to within the ±10% tolerance range. When the test frequency reaches 1MHz, the Samsung capacitor logs a capacitance measure of 5.159μF, which is only slightly higher than the benchmark value of 5.077μF for the same frequency.

Moving on to the measurements taken at 10 Volts, similar observations can be made, with the Samsung component demonstrating a comparable or, in some cases, better performance. For example, the Samsung capacitor's capacitance at a frequency of 5Hz is recorded as 5.05μF, whereas the benchmark average at the same voltage is slightly lower at 5.107μF. Significantly, the Samsung CL31B475KAHNNWE capacitor maintains its performance and remains close to the benchmark values as the test frequency continues to increase. At 600kHz, it measures a capacitance of 4.808μF, which showcases that Samsung's capacitor is considerably more stable in comparison to the benchmark average when operating at higher frequencies.

In summary, the Samsung CL31B475KAHNNWE capacitor exhibits commendable capacitance performance across different voltages and frequencies. Although it starts with a slightly lower capacitance compared to the benchmark average at lower frequencies, it showcases considerable stability and consistency as the test frequency rises, ensuring that it meets or surpasses the expected benchmark values. These characteristics make the Samsung CL31B475KAHNNWE a reliable and high-performing capacitor in various scenarios.

For example, at 50 Hz and 1 Volt, the CL31B475KAHNNWE had a series resistance of 23.07 Ohms, which is noticeably lower than the average series resistance of 27.59 Ohms found in the dataset. Similar comparisons can be made at 100 Hz (12.01 Ohms vs. 13.82 Ohms), 500 Hz (2.27 Ohms vs. 2.885 Ohms), and 10 kHz (61.02 mOhms vs. 188.5 mOhms). The substantial decrease in series resistance is crucial, as it results in lower power dissipation and higher efficiency for electronic systems.

At 10 Volts, the performance of this capacitor was evaluated up to 700 kHz. Although some data points were not provided, the available data indicates an improvement in series resistance at numerous test frequencies. For instance, at 50 Hz, the measured series resistance was 28.1 Ohms, and at 100 Hz, it was 14.72 Ohms. At higher frequencies, such as 1 kHz, the series resistance is 1.736 Ohms. These values demonstrate the effectiveness of the CL31B475KAHNNWE capacitor in maintaining low series resistance even at elevated voltage levels. This attribute is highly beneficial in various high-voltage applications, such as power management and signal conditioning circuits.
