It is designed for a wide range of applications, given its nominal capacitance value of 100n, a tolerance of ±10%, and a voltage rating of 50V. The capacitor's Ceramic: X7R dielectric composition has been long-standing in the industry, sought after for its stability and reliability. In this review, we seek to provide a detailed analysis of its performance by comparing the data acquired under two different voltage conditions: 1V and 10V, against the statistical benchmark. The intention here is to present a balanced perspective about its applicability for electronics engineers.

Pros:

• Well-researched manufacturer with a trusted reputation
• Demonstrated stability across various test frequencies
• Wide range of applications due to nominal capacitance and voltage rating

Cons:

• Decreasing Quality Factor at high frequencies
• Inconsistent performance across the entire frequency range

Impedance

The CC0805KRX7R9BB104 exhibits a lower impedance across most of the test frequency range compared to the average impedance observed in the statistical benchmark. This is particularly important in applications where minimizing the impedance is crucial for optimal circuit performance. High impedance values can result in undesirable voltage drops, reduced current flow, and a greater risk of signal integrity degradation.

For instance, at a 5 kHz test frequency, the capacitor reports an impedance of 310.1 Ohms, whereas the average impedance of the benchmark is 325.6 Ohms. This trend is maintained across the majority of the frequency spectrum, showcasing the CC0805KRX7R9BB104's superior performance in terms of impedance against its counterparts.

Furthermore, when the LCR measurements are taken at 10 volts, the component continues to demonstrate a lower impedance than the benchmark for most frequencies. Notably, at a 100 kHz test frequency, the CC0805KRX7R9BB104 presents an impedance of 15.15 Ohms, while the statistical benchmark average is 18.07 Ohms. This data solidifies the argument that this capacitor delivers a better impedance performance compared to the benchmark.

In conclusion, the CC0805KRX7R9BB104 capacitor provides a lower impedance response through a wide range of test frequencies. As the impedance plays a significant role in circuit behavior, choosing a component with reduced impedance levels can greatly affect the overall performance, especially in situations where maintaining ideal signal quality and maximizing current flow is essential.

Capacitance

When analysing the capacitor's performance, our focus will be on capacitance values compared against the statistical benchmarks at 1 Volt and 10 Volts. The Yageo CC0805KRX7R9BB104 ceramic capacitor has a nominal capacitance of 100nF and a tolerance of ±10%, which means the actual capacitance can vary between 90nF and 110nF.

When comparing the capacitance values of CC0805KRX7R9BB104 at 1 Volt against the pertinent statistical benchmark values, it becomes clear that the component performs at a superior level to other capacitors. Across test frequencies ranging from 5 Hz to 1 MHz, this capacitor consistently demonstrates higher capacitance values than the average series. Notably, at a test frequency of 5 Hz, the measured capacitance value of 105.4nF exceeds the benchmark average of 101.8nF by a significant margin. This tendency for exceptional performance is observable across the entire frequency spectrum.

Upon examining the capacitance values of CC0805KRX7R9BB104 at 10 Volts, we observe a notable increase in capacitance performance, providing further evidence of its superiority over the statistical benchmark. At a test frequency of 50 kHz, this component's capacitance value is 120.4nF, which outperforms both the benchmark average and its capacitance value at 1 Volt. It's essential to recognize that, while the capacitor provides exceptional effectiveness, the capacitance values experience a slight decrease at higher frequencies above 700 kHz. This drop could be attributed to the inherent properties of ceramic capacitors where an increase in frequency can result in a decrease in capacitance value. Additionally, other factors like variations in manufacturing processes, temperature, and the applied voltage can impact the capacitance value.

Series Resistance

Our comprehensive analysis examines the LCR measurements taken at 1 Volt and 10 Volts for the Yageo CC0805KRX7R9BB104 Ceramic: X7R capacitor. A crucial parameter in this review is the series resistance or equivalent series resistance (ESR), which affects performance in AC circuits by producing energy loss and heat dissipation. Lower ESR values are preferable as they indicate lower energy losses and better overall performance.

At 1 Volt, it's noteworthy that the series resistance values for this component are generally found to be lower than the average data seen in the statistical benchmark, particularly in the range of test frequencies from 5 kHz to 100 kHz. This suggests that the Yageo capacitor exhibits a superior performance in terms of series resistance within this frequency range.

For instance, at 5 kHz, the capacitor's series resistance is reported to be 4.546 Ohms, which is significantly lower than the benchmark's average of 10.02 Ohms. A similar trend is observed at 10 kHz and 20 kHz, with the capacitor displaying 2.286 Ohms and 1.133 Ohms, respectively, compared to benchmark averages of 5.163 Ohms and 2.629 Ohms. Evidently, in these frequency ranges, the Yageo capacitor outperforms those in the benchmark.

As we move towards higher frequencies, the capacitor continues to exhibit lower series resistance values compared to the benchmark data. For example, at 1 MHz, the Yageo capacitor registers an impressive 34.7 milliohms, while the benchmark average is significantly higher at 70.07 milliohms.

Conversely, the 10 Volts LCR measurements reveal that the component's performance is not as consistent as at 1 Volt compared to the benchmark. At test frequencies below 20 kHz, the Yageo capacitor shows higher series resistance values; however, from 50 kHz to 1 MHz, it yields lower series resistance values than the benchmark data. This is exemplified at 50 kHz, where the capacitor's series resistance is 878.2 milliohms, compared to the benchmark's average of 1.039 Ohms. Furthermore, at 1 MHz, the component's value is not reported, but the benchmark average is presumed to be in a similar range as the 1 Volt measurements.

In conclusion, the Yageo CC0805KRX7R9BB104 capacitor demonstrates a relatively strong performance in terms of series resistance at 1 Volt, particularly within the frequency range of 5 kHz to 100 kHz. At 10 Volts, its performance exhibits variability but remains competitive across specific frequency ranges.

Dissipation Factor and Quality Factor

Our data set comprises measurements of the CC0805KRX7R9BB104 Capacitor's Dissipation Factor (Df) and Quality Factor (Q) at two voltage levels: 1 Volt and 10 Volts, encompassing a comprehensive range of test frequencies from 5 Hz to 1 MHz. We will thoroughly examine this particular capacitor's performance and compare it to the statistical benchmark data obtained from experiments with other capacitors of the same value.

When tested at 1 Volt, the CC0805KRX7R9BB104 exhibits outstanding consistency in Df values, which is a measure of the efficiency of energy stored and lost in the dielectric material of the capacitor. It sustains a low Df of around 0.014 for the majority of the test frequencies, marginally increasing to only 0.021 at 1 MHz. These results indicate the component dissipates a minimal amount of energy as heat, making it suitable for use in energy-efficient applications, and in designs where maintaining low losses is crucial for optimal performance. On the subject of Q, a measure of the capacitor's ability to store and release electrical energy without significant losses, the part demonstrates remarkable performance. It peaks at a high of 80.35 at a test frequency of 50 Hz. Its Q value remains consistently above 60 across all test frequencies, except at 1 MHz, where it slightly declines to 48.80.

The performance of the CC0805KRX7R9BB104 at 10 Volts, however, presents a contrasting outcome. Although its Df values are higher, they vary from 0.043 to 0.022 throughout the test frequencies, maintaining within an acceptable range, especially for higher voltage applications. It is essential to highlight that higher Df values have a more significant impact on circuit performance, as the capacitor has more losses, which is undesirable in certain applications. On the other hand, the part's Q values at 10 Volts are notably lower compared to when tested at the 1 Volt level, oscillating between 23.04 and 46.00. The highest Q value at this voltage level occurs at a test frequency of 300 kHz, while its lowest emerges at merely 5 kHz. Alongside these lower Q values, the component, however, continues to demonstrate adequate performance when juxtaposed to the statistical benchmark. This is particularly crucial in determining the overall usability of this capacitor across various applications, voltage levels, and circuit complexities.

However, in higher voltage scenarios such as 10 Volts, the propagation of impedance values followed a relatively similar trend to that at 1 Volt. The capacitance at 10 Volts experiences significant deviation in comparison to the 1 Volt scenario, which warrants consideration in high-voltage applications.

Overall, the CC0805KRX7R9BB104 capacitor exhibits adequate performance characteristics when compared to the statistical benchmark data. Engineers should have no qualms about making an informed decision about incorporating it into their designs, as it represents a reliable choice for the typical range of capacitance values. Nevertheless, it is essential to assess the specific requirements of each application and choose the capacitor accordingly, particularly in high-voltage scenarios where the capacitance values may vary.
