Impedance

The CL32A476KOJNNNE ceramic capacitor, with its X5R dielectric material, shows increased impedance values at various test frequencies compared to the statistical benchmark average impedance for capacitors with the same nominal value. When tested at 1 Volt, the results demonstrate a relatively higher impedance value across most frequencies. For instance, at a test frequency of 5Hz, the impedance of the CL32A476KOJNNNE is 664.7 Ohms compared to a benchmark average of 656.9 Ohms. At the higher test frequency of 1MHz, the CL32A476KOJNNNE provides 10.29m Ohm impedance, significantly deviating from the benchmark average of 286.2m Ohms. The higher impedance could be observed in some cases, reaching a difference of at least 7.8 Ohms.

When the testing voltage is increased to 10 Volts, the CL32A476KOJNNNE capacitor continues to exhibit higher impedance values in comparison to the benchmark data set. For example, at the mid-range frequency of 50kHz, the CL32A476KOJNNNE displays a significant increase in impedance from the benchmark average of 344.1m Ohms to 103.2m Ohms.

Given the higher impedance values observed in the Samsung CL32A476KOJNNNE Ceramic: X5R capacitor, its performance may vary in specific applications when compared to components within the same category. Engineers should carefully evaluate the impedance behavior of the CL32A476KOJNNNE capacitor in their circuits, considering the requirements of their particular projects. A deeper understanding of the component's performance characteristics and their effect on the overall system design is necessary to ensure the alignment of the capacitor's impedance with each project's objectives. This analysis will assist engineers in making informed decisions about the suitability of the CL32A476KOJNNNE capacitor in their applications, balancing its impedance properties with the required circuit performance.

Capacitance

Upon analyzing the capacitance values, it is evident that the majority of series capacitance values measured at 1V reside within the acceptable range set by the sample benchmarks. Most notably, the CL32A476KOJNNNE exhibits outstanding performance at test frequencies ranging from 5 Hz to 300 kHz. However, its capacitance value drops below the minimum series capacitance at higher frequencies. This behavior could potentially be due to an inherent mechanical or dielectric property that may be consistent across the range of Ceramic X5R Capacitors.

The capacitance performance measurements exhibit a similar pattern, with exceptional performance demonstrated up to 300 kHz. Though the performance slightly declines at higher test frequencies up to 1 MHz, it eventually surpasses the average benchmark values in the 400 kHz to 700 kHz frequency range. This signifies a stable oscillating response suitable for applications operating within these frequency domains.

When evaluating the device data at a 10V operating voltage, it is clear that the CL32A476KOJNNNE offers remarkable performance capability in terms of maintaining capacitance within the benchmark range. It even achieves values significantly above the maximum benchmarks at higher frequencies above 400 kHz. This advanced performance is advantageous for applications and circuits operating at higher voltage levels, providing improved efficiency and signal stability.

Series Resistance

In the 1-Volt test scenario, the Samsung Electro-Mechanics CL32A476KOJNNNE capacitor displays proficient results across various test frequencies when compared to the statistical benchmark data. For example, at some crucial test frequencies like 1 kHz, it surpasses the benchmark's average series resistance (437.4 mΩ) by demonstrating a significantly lower resistance of 117.1 mΩ. At 250 kHz, the capacitor underperforms the benchmark marginally, as the recorded series resistance of 9.594 mΩ is moderately closer to the benchmark's average of 287.9 mΩ. However, overall, the component exhibits commendable performance in the 1-Volt test scenario.

In the 10-Volt test scenario, the data obtained substantiates the component's high-performance traits across various test frequencies. Although the results at certain frequencies are not available, the obtained values showcase exceptional performance. For instance, at 10 kHz and 50 kHz test frequencies, the CL32A476KOJNNNE records a significantly reduced series resistance of just 1.102 mΩ and 2.551 mΩ, respectively, compared to the corresponding benchmark average values of 330.6 mΩ and 295.7 mΩ.

The series resistance of a capacitor is essential as it can influence the efficiency, stability, and transient response of an electronic circuit. A lower series resistance enhances the capacitor's capability to smooth the input/output voltage in power delivery scenarios, providing better steady-state performance. Moreover, it reduces the capacitor's self-heating which further improves the component's longevity.

The Samsung Electro-Mechanics CL32A476KOJNNNE capacitor evidently demonstrates high reliability and performs commendably in comparison with the statistical benchmark. With its series resistance profile, this capacitor is an optimal choice for engineers who are exploring viable components that deliver satisfactory values against a statistical benchmark. Its performance in both 1-Volt and 10-Volt test scenarios signifies the component's versatility to function efficiently under varied voltage conditions, catering to a diverse range of applications in electronics engineering.

Dissipation Factor and Quality Factor

The Dissipation Factor (Df) and Quality Factor (Q) are essential parameters for capacitors, as they give insight into the capacitor's efficiency and energy loss when used within a circuit. Samsung Electro-Mechanics' CL32A476KOJNNNE capacitor showcases outstanding results in both Df and Q performance, making it a strong contender for various applications.

At a test frequency of 5 kHz and with 1 volt applied, the capacitor exhibits a low Df of 0.027 and a high Q of 37.38. These values are nearly two times better than the statistical benchmark data, indicating its excellent performance in this frequency range. Increasing the test frequency to 1 kHz, the capacitor registers an even lower Df value of 0.025 and a higher Q value of 39.68, showcasing its consistency in performance at lower frequencies.

However, as the test frequency increases to 300 kHz, the capacitor's performance metrics change, displaying a high Df value of 0.671 and a relatively low Q value of 1.50. It's worth noting that this specific capacitor does not provide performance data for test frequencies of 20 kHz, 75 kHz, 100 kHz, 150 kHz, 200 kHz, 250 kHz, and 750 kHz. This makes it difficult to ascertain its performance in those frequency ranges.

Additionally, when applying a higher voltage of 10 volts, the CL32A476KOJNNNE capacitor's performance significantly improves at certain frequencies. The 10 kHz test frequency serves as an example, where the capacitor displays an extraordinarily low Df value of 0.001 and an impressive Q value of 761.91 when compared to benchmark data. This further highlights the capacitor's exceptional performance at specific frequencies and high voltage conditions.

Considering the low Df and high Q values exhibited by the CL32A476KOJNNNE capacitor at specific test frequencies, it is evident that this capacitor is an optimal choice for engineers seeking efficient performance and minimal energy loss. When selecting a capacitor, it is crucial to keep in mind the requirements of your specific application and assess whether the performance characteristics align with it.
