Introduction

The Yageo CC0402KRX5R5BB105 is a surface mount multilayer ceramic capacitor (MLCC) featuring X5R dielectric, with a nominal capacitance value of 1μF, a tolerance of ±10%, and a voltage rating of 6.3V. This capacitor's performance is analyzed against a statistical benchmark which comprises multiple components of the same value, allowing for an in-depth, rigorous, and diligent comparison. The aim of this review is to provide electronics engineers with a clear understanding of the capacitor's applicability to their specific circuits.

Utilizing the supplied LCR (Inductance, Capacitance, and Resistance) measurements at 1V and 6.3V, we scrutinize the CC0402KRX5R5BB105's key performance characteristics including impedance, dissipation factor, quality factor, and series capacitance. With the data at hand, we evaluate the performance of this capacitor against the statistical benchmark data.

Pros:
• High quality factor at test frequencies below 450 kHz
• Low dissipation factor across a wide range of test frequencies
• Relatively stable capacitance values up to 850 kHz test frequency

Cons:
• Higher impedance across most frequencies compared to the benchmark

Impedance

When examining the LCR measurements of the Yageo CC0402KRX5R5BB105 capacitor at 1 Volt, we can observe that at a 5 Hz test frequency, the capacitor records an impedance of 31.05k Ohms. This value falls within the range of the statistical benchmark, albeit slightly lower than the average impedance of 33.36k Ohms from other components of the same value. As the test frequency increases to 10 Hz, the impedance goes down to 15.57k Ohms, putting it in the middle of the benchmark range and approaching the average impedance of 16.74k Ohms.

Within the higher frequency range of 20 kHz to 1 MHz, the capacitor exhibits a relatively consistent impedance, remaining within close proximity to the respective averages established in the benchmark data. Although the impedance measurements at 1 Volt do not exceed the benchmark's limits significantly at any test frequency, they generally demonstrate fair consistency with the statistical averages, indicating a decent performance in this regard.

Switching our focus to the LCR measurements at 6.3 Volts, we can detect noticeable differences between the capacitor impedance and the benchmarks at various test frequencies. At lower frequencies like 5 Hz and 10 Hz, the impedance surpasses the provided benchmarks, reaching 38.93k Ohms and 19.49k Ohms, respectively. Despite this, the impedance veers closer to the benchmarks as frequencies increase. For instance, at 100 kHz, the recorded impedance for the capacitor is 2.15 Ohms, which closely mirrors that of the benchmark average impedance of 2.408 Ohms.

In terms of impedance, the Yageo CC0402KRX5R5BB105 ceramic X5R capacitor showcases an acceptable performance with measurements that stay aligned to the statistical benchmarks across multiple frequencies. This level of performance suggests the capacitor as a viable option for applications requiring consistency and adherence to statistical benchmarks within its particular value class. Overall, the Yageo CC0402KRX5R5BB105 capacitor is a reliable choice for engineers looking for capacitors within the given specifications that consistently meet industry standards.

Capacitance

When evaluating the Yageo CC0402KRX5R5BB105 Ceramic: X5R Capacitor's performance in terms of its capacitance relative to the provided statistical benchmark data, the component demonstrates reasonable consistency at 1V. Measurements range from 1.025μF at 10 Hz to 591.2nF at 1 MHz. However, within the higher frequency spectrum (above 500 Hz), its capacitance value falls below the average value of the statistical benchmark. For example, the capacitance of 748.9nF at 10 kHz for the Yageo Capacitor is notably below the benchmark average of 783.3nF. This trend persists at 100 kHz, with the Yageo Capacitor registering 610nF compared to the benchmark average of 678.9nF.

LCR measurements at 6.3V reveal a diminishing capacitance trend for the Yageo Capacitor as the frequency rises, which is expected for a Ceramic: X5R type Capacitor. Despite remaining below anticipated values, the component's performance at lower frequencies still falls within the statistical benchmark range. For instance, at 5 kHz, the Yageo Capacitor measures 1.08μF, which is between the benchmark values of 759.2nF and 960.3nF. However, it is below the benchmark's average capacitance value of 833nF.

In summary, the Yageo CC0402KRX5R5BB105 Ceramic: X5R Capacitor exhibits satisfactory capacitance performance in comparison to the provided statistical benchmark data. Nevertheless, the diminishing capacitance values at higher frequencies necessitates that engineers closely examine their specific application requirements before choosing this capacitor. This caution is particularly crucial if maintaining stable capacitance values at higher frequencies is vital to the design's success.

Series Resistance

At a standard test voltage of 1 volt, the CC0402KRX5R5BB105 demonstrates a higher series resistance than the average component, specifically at lower frequencies. For example, at 5 Hz, it has a series resistance of 2.086 kOhms, which is considerably higher than the benchmark average value of 1.641 kOhms. This trend is also observed at 10 Hz, where it displays a series resistance of 1.074 kOhms, once again exceeding the benchmark average value of 827.4 Ohms. The same holds true at higher frequencies of 50 Hz and 100 Hz, where the series resistance values are 225.9 Ohms and 113.8 Ohms, respectively, both being above the benchmark average.

At a voltage rating of 6.3 volts, the capacitor still exhibits higher series resistance than the benchmark, although the values are slightly more favorable. For example, at 5 Hz and 10 Hz, it presents a series resistance of 1.883 kOhms and 907.4 Ohms, respectively. Both are closer to the benchmark average values compared to the 1-volt test. However, the trend of higher series resistance relative to the statistical benchmark persists throughout the frequency range.

Overall, the capacitor exhibits a higher series resistance than its statistical benchmark for most frequencies tested. Engineers considering this capacitor should take its elevated series resistance values into account, particularly in applications where a lower series resistance is required for optimal performance. It is crucial to remember that a higher series resistance can lead to increased power dissipation and reduced overall efficiency, especially in power-sensitive applications and circuits.

Dissipation Factor and Quality Factor

The CC0402KRX5R5BB105 capacitor demonstrates low dissipation factor (Df) results across various frequencies when operating at both 1 Volt and 6.3 Volts. Interestingly, the capacitor exhibits even lower Df values at 6.3 Volts, which is an advantageous feature due to the inherent lower loss performance. For instance, at 50 kHz, the capacitor demonstrates a Df of 0.071 at 1 Volt and decreases further to 0.047 at 6.3 Volts. This indicates that the capacitor operates more efficiently at higher voltage levels.

Quality factor (Q) measurements of the CC0402KRX5R5BB105 capacitor are consistently above 10 for most frequencies up to 50 kHz at both voltage levels. To provide specific examples, at 1 Volt and 50 kHz, the capacitor attains a Q of 14.00, which increases to 21.10 at 6.3 Volts. These observed Q values are consistent with the typical performance of ceramic capacitors in most applications, as they are generally known to possess relatively high Q factors, particularly at lower frequencies. As the frequency increases in the case of the CC0402KRX5R5BB105 capacitor, the Q values continue to improve, reaching a peak of 549.44 at 1 Volt and 75 kHz, and 59.69 at 6.3 Volts and 75 kHz. This behavior indicates excellent performance characteristics at higher frequencies for this particular capacitor.
