Some of the key characteristics we will be focusing on in this review include the capacitance value, series resistance, dissipation factor, and quality factor at various test frequencies.

Impedance

In the lower frequency range (5 Hz and 10 Hz), the Yageo CC0603KRX7R6BB105 component's impedance values closely resemble the benchmark, measured at 32.54kΩ and 16.31kΩ, respectively, compared to the average values of 33.36kΩ and 16.74kΩ. The close alignment is expected, given that impedance typically shows more similarities with resistance at lower frequencies.

This similarity continues at mid-range frequencies (50 Hz and 100 Hz) as well, with the component impedance values recorded at 3.284kΩ and 1.647kΩ, compared to the average 3.385kΩ and 1.702kΩ. Consistent behavior in lower and mid-range frequencies reaffirms the Yageo CC0603KRX7R6BB105's reliability in a range of impedance-sensitive circuits.

Moving into higher frequency ranges such as 1 kHz, 5 kHz, and 10 kHz, the Yageo CC0603KRX7R6BB105 once again closely aligns with the statistical benchmark values. At 500 Hz, the component's impedance sits slightly lower (332.6Ω) compared to the average value of 345Ω. This mild deviation indicates that the capacitor may offer smoother current flow in the related circuitry, depending on the requirements of the specific application.

At higher test frequencies such as 20 kHz, 50 kHz, and 100 kHz, the component's impedance (9.234Ω, 3.77Ω, and 1.908Ω, respectively) remains relatively close to the benchmark data. This trend persists through to the frequency range of 150 kHz (1.28Ω) up to 1 MHz (210.7mΩ), signifying that the Yageo CC0603KRX7R6BB105 maintains a similar impedance pattern compared to the average values across a wide frequency spectrum. By adhering to standard impedance specifications, the Yageo CC0603KRX7R6BB105 demonstrates its dependability in diverse applications and frequency ranges, making it a valuable choice for many electronic designs.

Capacitance

When the CC0603KRX7R6BB105 is tested at 1V, its capacitance values tend to be higher than the benchmark data. More specifically, at a test frequency of 5kHz, its capacitance of 978.8nF surpasses the benchmark's average (962.5nF) by 16.3nF. This trend continues at other test frequencies up until 1kHz, where the capacitor's capacitance starts to deviate from the benchmark values.

Interestingly, as we approach higher test frequencies (e.g., 20kHz to 50kHz), the capacitance of the CC0603KRX7R6BB105 becomes closer to the benchmark data. However, it is essential to point out that the capacitor still maintains capacitance values above the benchmark's average at the tested frequencies up to 1MHz.

When evaluated under a higher voltage of 10V, the CC0603KRX7R6BB105 demonstrates superior performance compared to the benchmark's values at lower test frequencies (5kHz to 1kHz). At higher test frequencies, however, the capacitor exhibits fluctuating performance in comparison to the benchmark. Its capacitance values align with the benchmark at around 20kHz, surpass it at 1kHz, and then decrease again as it approaches 50kHz. Eventually, at frequencies between 75kHz and 1MHz, the capacitor's capacitance becomes relatively similar to the benchmark data.

Taking these results into account, the CC0603KRX7R6BB105 capacitance performance is consistently better than the statistical benchmark at lower test frequencies, rendering it a reliable option for circuits that necessitate stable capacitance values within this range. Nonetheless, its performance at higher test frequencies varies, which ought to be factored in when assessing its suitability for specific circuit designs. It is imperative to consider the operating frequency range requirements of the intended application to determine if this capacitor will serve its purpose well, while maintaining stability and accuracy in capacitance values.

Series Resistance

At a test frequency of 5 Hz, the CC0603KRX7R6BB105's Equivalent Series Resistance (ESR) measures 806.9 Ohms, which is slightly above the benchmark average of 1.641 KOhms but still well within the minimum and maximum range of 794.5 Ohms and 2.648 KOhms, respectively. Similarly, at 10 Hz, the capacitor's ESR measures 400.1 Ohms, close to the average benchmark value of 827.4 Ohms and well between the minimum and maximum range of 392.6 Ohms and 1.333 KOhms.

As the test frequency increases, the capacitor's ESR measurements continue to remain close to the benchmark values. At 50 Hz, the CC0603KRX7R6BB105 has an ESR of 81.15 Ohms, when compared to the benchmark average of 171.3 Ohms, it sits comfortably in the range of 79.01 Ohms and 278.5 Ohms. At a frequency of 100 Hz, its ESR is 41.84 Ohms, almost half of the benchmark average of 87.92 Ohms but still within the range of 40.83 Ohms and 144.4 Ohms. It is essential to understand that a lower ESR value is generally more desirable as it results in better performance against ripple currents and allows for greater capacitance retention during high-frequency operations.

Progressing further, at higher test frequencies such as 500 Hz, 1 KHz, and 5 KHz, the CC0603KRX7R6BB105 capacitor's ESR measurements exhibit a consistent pattern of lower values compared to the benchmark averages – 8.796 Ohms vs. 18.63 Ohms, 4.348 Ohms vs. 9.566 Ohms, and 648 milliOhms vs. 1.937 Ohms, respectively. However, these values still fall within the acceptable range limits specified in the benchmark data. A lower ESR is vital at higher frequencies for increased efficiency and reduced power losses in electronic circuits.

Moving to 10 KHz and 20 KHz test frequencies, the capacitor's ESR measurements are 226.3 milliOhms and 42.2 milliOhms. In comparison, the benchmark average values are 863.5 milliOhms and 328.9 milliOhms, with the capacitor's results falling well within the minimum and maximum range limits. These observations indicate that the CC0603KRX7R6BB105 capacitor exhibits a solid ESR performance at various frequencies across the spectrum, making it suitable for a wide range of applications involving high-frequency operations.

Dissipation Factor and Quality Factor

By examining the provided LCR measurements at 1 Volt and 10 Volts for the capacitor, we can make informed comparisons to the statistical benchmark data typically expected for capacitors with similar values in the market. These indicators are essential in determining the efficiency and performance of capacitors in real-world applications.

Upon analyzing the first set of measurements at 1 Volt, we notice a fairly consistent Dissipation Factor (Df) of 0.025 up to 100 kHz test frequency. This value demonstrates the capacitor's ability to efficiently store and release electrical energy. The Df experiences a marginal increase to 0.026 from 500 kHz to 1 MHz. As we increase the frequency to 5 kHz, there is a significant drop in the Df to 0.018, indicating an improved performance. This downward trend continues until the test frequency reaches 20 kHz, where the lowest Df is recorded as 0.004, making it a competitive candidate amongst its peers.

Examining the Quality Factor (Q), the capacitor shows promising values. This metric is important because it represents the ratio of stored energy to dissipated energy per cycle. The capacitor registers a consistent Q level, hovering around 40 from 5 kHz to 100 kHz. As the test frequency reaches 5 kHz, a rapid increase in Q is observed, peaking at 54.62. The Q factor climbs further as the frequency goes up, with an impressive value of 221.11 at 20 kHz. This high Q factor reflects a capacitor with minimal energy loss and excellent energy storage efficiency.

Moving to the LCR measurements at 10 Volts, we observe that the Dissipation Factor remains close to its performance at 1 Volt, with only slightly increased values across the observed test frequencies. This increase in Df indicates a minimal loss in performance due to an increase in applied voltage. Regarding the Quality Factor, the capacitor experiences a minor dip in values across the frequency range, but these values remain within the acceptable range for capacitors of its class, thus ensuring reliable performance.

Overall, thorough examination of both the Dissipation Factor and Quality Factor reveals that this particular capacitor strikes a balance between energy loss and storage performance, making it a strong contender in the market for capacitors with similar specifications.
