Impedance

An in-depth analysis of the impedance at various test frequencies for the Murata Electronics GCM155R71C104KA55J ceramic capacitor, when compared to statistical benchmark data, will provide valuable insights for engineers seeking the optimal capacitor choice for their applications.

At lower test frequencies such as 5 kHz and 10 kHz, the GCM155R71C104KA55J reports slightly higher impedance values of 330.2 kΩ and 165.5 kΩ, compared to the benchmark averages of 313.4 kΩ and 157.2 kΩ, respectively. This higher impedance may affect the capacitor's performance in certain applications requiring lower impedance values at these frequencies.

On the other hand, at higher test frequencies, the GCM155R71C104KA55J delivers relatively close impedance values to the benchmark, with only minor deviations. For example, at 50 kHz, the GCM155R71C104KA55J performs marginally below the benchmark average impedance, reporting 33.3 kΩ against the average of 34.91 kΩ. Similarly, at 100 kHz and 200 kHz, it exhibits 18.18 kΩ and 9.223 kΩ, which are quite comparable to the benchmark average values of 18.07 kΩ and 9.318 kΩ, respectively.

Upon examining the LCR measurements at 10 Volts, it is revealed that the impedance values of GCM155R71C104KA55J closely resemble those observed at 1 Volt. With only a slight variation, the capacitor's performance remains consistent across both voltage ratings, indicating its robustness and reliability.

Given the slight deviations from the benchmark values in certain frequencies, it is essential for engineers to carefully analyze their specific application requirements before selecting this capacitor. The provided data highlights the importance of considering the varying impedance values across different test frequencies and voltage ratings, ensuring the chosen capacitor will accurately match the needs of the electronic system being designed.

In this section, we will analyze the capacitance performance of the GCM155R71C104KA55J capacitor in comparison to the statistical benchmark for capacitors with the same nominal value. The nominal capacitance value of this capacitor is 100nF, which is common for various electronic circuit applications such as filtering, coupling, and decoupling.

Starting with the LCR measurements at 1 Volt, the capacitor's series capacitance ranges between 96.43nF at 5 Hz and 84.47nF at 1 MHz in this test environment. When compared to the average capacitance values in the statistical benchmark, the capacitor performs consistently lower across all test frequencies. For example, at 20 kHz, the GCM155R71C104KA55J demonstrates a series capacitance of 91.4nF compared to the benchmark's average of 94.99nF. This could indicate that the tested capacitor has lower capacitance tolerance when compared to the average capacitors in the same class.

Moving on to the 10 Volts LCR measurement, we can observe a similar trend. The capacitor's series capacitance values range from 97.12nF at 5 Hz to 83.69nF at 500 kHz (with measurements unavailable above this frequency). In this test environment, the capacitor's performance is more comparable to the statistical benchmark at lower frequencies, achieving a series capacitance of 94.37nF at 10 kHz, just slightly below the benchmark's average of 96.9nF. The difference in performance increases as the frequency rises, reaching a more significant gap of 2.68nF at 200 kHz with the benchmark average capacitance at 85.98nF.

It should be noted that a capacitor's capacitance value can vary depending on the applied voltage, temperature, and frequency of operation. When selecting a capacitor for a specific application, it is essential to ensure that it can meet the performance requirements under real-world conditions.

Overall, the GCM155R71C104KA55J capacitor consistently exhibits lower capacitance values when compared to the statistical benchmark data across the entire test frequency range. Engineers assessing the suitability of this capacitor for their circuits should consider this performance deviation in their design processes, especially when higher capacitance values are essential for their desired application. Close attention should be paid to the capacitance tolerance specified by the manufacturer, as well as the environmental factors and operating conditions that can affect the capacitance value of the chosen capacitor in the circuit.
