Impedance

When evaluating the impedance performance of the CC0402KRX7R8BB104 capacitor, it is essential to study its measurements at different voltage levels and various test frequencies. A comprehensive analysis of the impedance values will help us understand how well it performs compared to the average impedance values derived from the statistical benchmark data for capacitors within the same category, particularly those with a Ceramic: X7R composition.

At a 1 Volt level, CC0402KRX7R8BB104's impedance measurements are notably close to the statistical benchmark average across a range of test frequencies. For instance, at a 50 kHz test frequency, the capacitor's impedance is measured at 35.06 Ohms, which is just slightly above the benchmark average of 34.91 Ohms. Likewise, at 100 kHz, the component's impedance registers at 18.05 Ohms, barely deviating from the benchmark average of 18.07 Ohms.

The capacitor retains this consistent performance when impedance measurements are examined at the 10 Volt level. For example, at a test frequency of 50 kHz, the component has an impedance of 29.57 Ohms, compared to the statistical benchmark average of 34.91 Ohms. Although a different test frequency of 100 kHz yields a slightly lower impedance value of 15.65 Ohms, it is still in proximity to the benchmark's 18.07 Ohms.

In conclusion, the CC0402KRX7R8BB104 capacitor exhibits a reliable impedance performance at both 1 Volt and 10 Volt levels and across various test frequencies. Consequently, it can be considered as a competitive component that aligns closely with the average impedance values of other capacitors within the same category and composition. Understanding these impedance characteristics is crucial for designing electronic circuits that require stable and consistent performance across different voltage levels and test frequencies.

Capacitance

The Yageo CC0402KRX7R8BB104 was meticulously evaluated in terms of capacitance over various test frequencies, ranging from 5 Hz to 1 MHz. The measurements were compared against a comprehensive statistical benchmark dataset comprising capacitors with similar values and characteristics to provide a fair assessment of this specific product.

When assessed at the lower test voltage of 1 Volt, the CC0402KRX7R8BB104 maintained capacitance values closely aligned with the average series capacitance of the benchmark data for multiple frequency points. Notably, the measured capacitance values were higher relative to the benchmark range of minimum and maximum capacitances for frequencies above 20 kHz, indicating a slightly higher-than-expected capacitance performance at these frequencies. This characteristic may be beneficial for certain applications but must be weighed against other design considerations. Nonetheless, for engineers focused on low-frequency operation, the CC0402KRX7R8BB104 continues to deliver performance in accordance with the average series capacitance values found in the statistical benchmark dataset.

Assessment at a higher test voltage of 10 Volts revealed more nuanced aspects of the CC0402KRX7R8BB104's capacitance performance. The measured capacitance values were consistently higher than the benchmark dataset across a frequency range spanning from 5 Hz up to 75 kHz, signifying that this capacitor might be better suited to applications necessitating increased capacitance values in the presence of higher voltage levels. However, above 75 kHz, the measured capacitance values began to fall below the values found in the benchmark dataset. This finding indicates potential performance degradation in the high-frequency domain when voltage levels are elevated. Engineers should carefully evaluate these unique performance characteristics when evaluating the suitability of the CC0402KRX7R8BB104 for a particular application, paying close attention to their specific voltage and frequency requirements.

Series Resistance

Series resistance is a crucial property that directly affects a capacitor's performance, primarily because it has an impact on power losses. In this review, the performance of the Yageo CC0402KRX7R8BB104 capacitor will be compared to a statistical benchmark representing a collection of devices with the same nominal capacitance value of 100nF.

The CC0402KRX7R8BB104 exhibits a series resistance of 8.732k Ohms at the lowest test frequency of 5 Hz. This is very close to the benchmark's average series resistance of 8.751k Ohms. As the test frequencies increase, the capacitor's performance begins to show slight variations from the benchmark. At 10 Hz, the device exhibits a resistance value of 4.311k Ohms, compared to the benchmark's average value of 4.329k Ohms. By the time the frequency reaches 100 kHz, the capacitor displays a series resistance of 373.6m Ohms, which is significantly lower than the statistical benchmark's average value of 491m Ohms.

Interestingly, this Yageo capacitor outperforms the benchmark at higher frequencies. At 1 MHz, its series resistance measures 42.61m Ohms, which is much lower than the benchmark's maximum (845.4m Ohms) and average (70.07m Ohms) values. This suggests that the capacitor could be an excellent option for high-frequency applications where low power losses are desired.

As the applied voltage magnitude to the CC0402KRX7R8BB104 increases, the capacitor's series resistance demonstrates a corresponding reduction across all tested frequencies. For example, at 10 Volts, the series resistance at a frequency of 1 MHz decreases from 42.61m Ohms (at 1 Volt) to a minimal value of 27.37m Ohms.

Though the Yageo CC0402KRX7R8BB104 does not exhibit significant deviations from the benchmark's average series resistance across the tested frequency range, its performance at 10 Volts indicates that it could be an excellent choice for high-frequency applications requiring minimal power losses. Such a characteristic makes this capacitor suitable for efficiently managing power consumption in electronic circuits operating in demanding conditions. Overall, the capacitor's series resistance performance provides valuable insights for selecting ideal components for specific applications.

Dissipation Factor and Quality Factor

The capacitor exhibited a low Dissipation Factor when tested at both 1V and 10V. The recorded values reach a minimum of 0.018 at 300 kHz at 1V and 0.033 at 600 kHz and 650 kHz at 10V, respectively. In comparison to the benchmark data, these values indicate that the capacitor offers effective energy dissipation throughout a range of frequencies. A low dissipation factor is desirable, as it means that less energy is dissipated as heat and allows the capacitor to operate more efficiently.

Focusing on the Quality Factor (Q), the performance achieved by the capacitor presents substantial results. At a test voltage of 1V, the maximum Q value reached is 54.01 at 300 kHz, while at 10V, the peak is 29.96 at 650 kHz. This data demonstrates a consistently high Quality Factor performance throughout the tested frequency range, highlighting that the capacitor can support various electronics applications that require high Q devices. Quality Factor is a measure of the quality of a resonant circuit, which is inversely proportional to the dissipation factor. A higher Q value indicates a more efficient capacitor with lower losses and improved stability at a given frequency. This makes such capacitors suitable for various applications, such as tuning and filtering circuits, where efficiency, minimal heat generation, and consistent performance are essential.
