In this technical review, the performance of this capacitor is quantitatively analyzed in comparison to the provided statistical benchmark data. The focus will be on the key aspects that influence the decision-making of electronics engineers who evaluate this component's suitability for their applications, including capacitance, series resistance, dissipation factor, quality factor, and self-resonance behavior.

Impedance

When examining the impedance performance of the KEMET C0603C104K4RAC7867 Ceramic X7R capacitor, we can gain insights by comparing its characteristics to a statistical benchmark with a test voltage of 1 Volt. At lower test frequencies of 5 Hz and 10 Hz, the impedance measured 323k Ohms and 162k Ohms respectively, which are slightly above the average impedance values of 313.4k Ohms and 157.2k Ohms. This implies that the low frequency performance is marginally weaker compared to the benchmark components, and there may be room for improvements in these areas.

Nevertheless, as we move on to higher test frequencies, we note an improvement in the impedance values of the capacitor, as they begin to align more closely with the average values of the statistical benchmark. For instance, at a test frequency of 100 kHz, the capacitor registers an impedance of 17.48k Ohms, which is a reasonable match for the benchmark average value of 18.07k Ohms. This observed change indicates that the capacitor's impedance performance improves as the frequency increases.

Furthermore, when examining the impedance values at higher test frequencies such as 500 kHz and 1 MHz, we can observe that the KEMET component demonstrates even better alignment with the statistical benchmark average. Specifically, at these frequencies, the component exhibits impedances of 3.593k Ohms and 1.81k Ohms, which are within close proximity of the benchmark average values of 3.849k Ohms and 1.958k Ohms, respectively.

When evaluating the C0603C104K4RAC7867 capacitor's performance at an increased voltage of 10 Volts, a similar trend is observed. At low test frequencies, such as 5 Hz and 10 Hz, the component's impedance is below the benchmark average, reaching values of 267k Ohms and 133.8k Ohms, and deviating from the statistical benchmark's averages of 313.4k Ohms and 157.2k Ohms. These results further emphasize the need for the capacitor's low-frequency optimization.

As the test frequency escalates to 100 kHz, the capacitor's impedance narrows the gap with the benchmark values, yielding an impedance figure of 16.02k Ohms, which is in close proximity to the statistical average of 18.07k Ohms. Moreover, at higher test frequencies such as 500 kHz and 1 MHz, the component records impedance values of 3.423k Ohms and 1.718k Ohms, almost aligning with the benchmark averages of 3.849k Ohms and 1.958k Ohms. These results indicate that the KEMET C0603C104K4RAC7867 capacitor exhibits superior performance at higher frequencies and sheds light on areas that may benefit from further optimization.

Capacitance

When evaluating the capacitance of the KEMET C0603C104K4RAC7867 capacitor, LCR measurements were taken at two different voltage levels, 1 Volt and 10 Volts, across a frequency range from 5 Hz to 1 MHz. At 1 Volt, the observed capacitance values ranged from 98.54nF at 5 Hz to 87.94nF at 1 MHz. Comparing these results to statistical benchmark data, it can be concluded that the performance of this capacitor is relatively consistent at low frequencies (5 kHz and under), with the series capacitance values falling slightly below or within the average range. However, as the frequency increases, the capacitor's values generally exhibit a more significant deviation below the benchmark averages, reaching up to 6% deviation at higher frequencies. This information is valuable when considering the suitability of this capacitor for various applications that require a capacitor with stable performance across a broad frequency range.

In contrast, when examining the C0603C104K4RAC7867 LCR measurements taken at 10 Volts, the capacitance values ranged from 119.4nF at 5 Hz to 92.05nF at 700 kHz. It is noteworthy that the capacitance values observed in the 10 Volts test were significantly higher than the statistical benchmark at multiple frequencies, with the largest deviation reaching 23% difference in capacitance values. Although the data for frequencies of 750 kHz and above at 10 Volts is missing, the available data strongly suggests that the behavior of the C0603C104K4RAC7867 does change with the voltage applied, predominantly at lower frequencies.

From this analysis, it can be understood that the performance and behavior of the KEMET C0603C104K4RAC7867 capacitor are affected by the applied voltage and operating frequency. Users should consider these factors when choosing a capacitor for their specific application needs, particularly in scenarios where stable performance across a wide range of frequencies and voltages is required. Additionally, engineers can use the data presented in this analysis to make informed decisions regarding the suitability of this capacitor for their particular designs, ensuring optimal performance and reliability of the electronic systems in which they are incorporated.

Series Resistance

The series resistance performance of the KEMET C0603C104K4RAC7867 capacitor is critical when evaluating capacitors for use in professional circuit designs. To gain a comprehensive understanding of its capabilities, this analysis compares the component's series resistance values with the provided statistical benchmark data.

At a test voltage of 1V across various frequencies, the series resistance of the KEMET C0603C104K4RAC7867 capacitor demonstrates a decreasing trend as the frequency increases. The component's trend is consistent with the statistical benchmark data, indicating reliable performance. For instance, at a frequency of 5 Hz, the capacitor's series resistance measures at 4.92k ohms, which is notably lower than the benchmark's average of 8.751k ohms. Similarly, at 10 kHz, the component registers a series resistance of 2.724 ohms, outperforming the benchmark's average of 5.163 ohms.

When the test voltage is increased to 10V, the series resistance of the KEMET C0603C104K4RAC7867 capacitor exhibits the same decreasing trend with rising frequencies. At these higher test voltages, the component's series resistance values tend to be greater than those observed at lower voltages. However, the capacitor still performs competitively compared to the benchmark averages for frequencies where possible. For example, at 5 kHz, its series resistance is 15.46 ohms, significantly lower than the benchmark's average of 25.32 ohms.

In conclusion, the KEMET C0603C104K4RAC7867 capacitor offers competitive series resistance performance relative to the statistical benchmark data for capacitors with the same value. This indicates that it could be a suitable choice for engineers aiming to integrate components with lower series resistance into their circuit designs. However, engineers should consider the priority of series resistance in relation to other factors when selecting capacitors for specific applications, as there may be other performance aspects equally or more important for the targeted use cases.

Dissipation Factor and Quality Factor

When analyzed at a voltage of 1V, the KEMET C0603C104K4RAC7867 demonstrates a low dissipation factor (Df) ranging from 0.014 at 50 kHz to a maximum of 0.020 at 1 MHz. These low Df values are advantageous since they indicate reduced power losses, which are optimal for engineers aiming to enhance overall power efficiency in their electronic designs. At the same voltage rating, the capacitor's quality factor (Q) values range from 66.03 at 5 kHz to a high of 73.46 at 100 kHz, providing respectable performance characteristics.

When the voltage applied was increased to 10V, Df values ranged from 0.031 at 100 kHz to a maximum of 0.056 at 5 kHz and 17.80 kHz. These values suggest that when the KEMET C0603C104K4RAC7867 operates at higher voltages, the level of energy dissipation experienced remains low. This low dissipation contributes to improved power efficiency for the devices it is integrated into. As for the Q values at 10V, the capacitor's performance remains impressive, with a range of 18.14 at 5 kHz to a peak of 43.49 at 550 kHz. While the Q values witness a downward trend at frequencies above 550 kHz, the capacitor still exhibits excellent proficiency up to this point.

It is essential to comprehend the significance of the Df and Q values as they directly impact the performance of capacitors in electronic applications. The Df is the ratio of the active power (losses) to the total reactive power and helps to quantify the capacitive component’s power losses. A low Df, as exhibited by the KEMET C0603C104K4RAC7867, indicates lower power dissipation, leading to increased power efficiency. In contrast, the Q value, defined as the inverse of the dissipation factor, represents the capacitive component's energy storage efficiency. A higher Q value indicates lower losses and better overall component performance.

In comparison to the statistical benchmark data, the KEMET C0603C104K4RAC7867 showcases low Df values and high Q values within the frequency range tested. These characteristics point toward lower power dissipation and acceptable equivalent series resistance (ESR), making it a suitable choice for electronic engineers considering implementing Ceramic: X7R capacitors in their designs. The KEMET C0603C104K4RAC7867 capacitor maintains a position of reliable performance following the analysis presented in this review section, contributing effectively to electronic applications that demand high-performing and efficient capacitors.

For most applications, particularly for electronics engineers assessing this capacitor for use in their circuits, these performance aspects should be suitable. However, the higher Dissipation Factors observed at lower frequencies may be a concern for certain applications where minimized energy loss is critical. Therefore, engineers may want to evaluate other capacitors within the Ceramic: X7R category with a lower Dissipation Factor at these specific frequencies, if required for their applications.
