Series Resistance

An in-depth analysis of the series resistance of the GRM155R71H104KE14D ceramic capacitor, manufactured by Murata Electronics, reveals crucial insights into the performance characteristics of this component. When subjected to LCR measurement values at 1 Volt, the capacitor's series resistance values ranged from a high of 5.855k Ohms at 5 kHz to a low of 35.77m Ohms at 1 MHz. A comparison with the statistical benchmark data for capacitors of the same value reveals that the GRM155R71H104KE14D exhibits higher series resistance values in the lower frequency ranges, while showcasing superior performance as the frequency increases.

For example, at 5 kHz, the component's series resistance of 5.855k Ohms is less favorable when compared to the average benchmark value of 8.751k Ohms. However, at 1 MHz, the GRM155R71H104KE14D achieves a series resistance value of 35.77m Ohms, which is a significant improvement compared to the benchmark average of 70.07m Ohms. This noteworthy performance at higher frequencies makes the capacitor an attractive option for engineers to consider when designing circuits operating within that range.

Upon evaluating the LCR measurements taken at 10 Volts, the GRM155R71H104KE14D capacitor exhibited results with a peak series resistance value of 14.95k Ohms at 5 kHz, while the minimum value reached 67.26m Ohms at 650 kHz. In comparison with the benchmark data, it becomes apparent that the GRM155R71H104KE14D continues to present higher series resistance values at lower frequency ranges. Nonetheless, the capacitor exhibits commendable performance when operating at higher frequencies. For instance, at 50 kHz, the capacitor's series resistance is measured at 1.319k Ohms, which is only slightly above the benchmark average.

Due to the marginally higher series resistance values observed at lower frequencies, engineers should exercise caution when incorporating the GRM155R71H104KE14D ceramic capacitor into circuits that require optimal low-frequency performance. However, given the impressive series resistance values demonstrated by the capacitor at elevated frequencies, the GRM155R71H104KE14D capacitor emerges as a compelling choice for engineers in the development of high-frequency circuits.

Dissipation Factor and Quality Factor

The GRM155R71H104KE14D capacitor, a Ceramic (X7R) type, exhibits promising dissipation factor (Df) values when tested at 1 Volt. The Df values range from 0.015 at 100 kHz to 0.020 at 1 MHz, indicating low energy dissipation and reduced ESR, which is generally desirable in electronic circuits. Additionally, this component showcases impressive results in terms of quality factor (Q), which is a measure of the capacitor's efficiency and resonant characteristics. The Q values range from 49.80 at 1 MHz to 67.98 at 150 kHz, representing a decent range of energy-storing capabilities and minimal losses.

Upon examining the capacitor's performance at 10 Volts, the GRM155R71H104KE14D demonstrates higher Df measurements in comparison to the 1 Volt testing, expanding across a range of 0.025 at 600 kHz to 0.051 at 5 Hz. This increase in Df values may result in a more considerable energy dissipation and a slightly increased ESR. Correspondingly, the Quality Factor appears to degenerate slightly as well, with values between 19.47 at 5 Hz to 40.92 at 550 kHz, indicating a decline in the capacitor's performance at elevated voltages.

While comparing the GRM155R71H104KE14D capacitor to the benchmark data, we can observe that it presents a fairly consistent profile across different test frequencies. When operating at 1 Volt, the Df values are promising, and the Q values depict a decent range, making it suitable for applications that prioritize low energy losses and efficient energy storage characteristics. However, an increase in voltage to 10 Volts brings subtle degeneration in both Df and Q values, which might impede the overall performance of this particular capacitor in specific applications. Hence, it is essential to consider the operating voltage and frequency range requirements, along with other crucial parameters such as temperature stability, capacitance change, and interference, while selecting the appropriate capacitor for your design application.
