Impedance

Let us evaluate the impedance performance of the Murata Electronics GCM155R71H104KE02D capacitor by comparing it to the provided statistical benchmark data. This analysis serves as a valuable resource for engineers looking to determine the performance of this capacitor in their circuits.

When examining the GCM155R71H104KE02D alongside the benchmark data at 1 Volt, we observe that its impedance values remain consistent across nearly all frequencies, in line with the average impedance values of the benchmark. For example, at 50 kHz, the impedance of the GCM155R71H104KE02D is recorded as 32.11k, only marginally deviating from the average impedance of 31.67k within the benchmark data. A similar pattern is observed at 100 kHz, where the component's impedance value of 17.38k is slightly lower than the average benchmark impedance at 18.07k. These minuscule deviations suggest that the GCM155R71H104KE02D follows the general trend observed among its counterparts.

Proceeding to analyze the performance of the GCM155R71H104KE02D at 10 Volts reveals a similar pattern. Though the impedance at 50 kHz is measured at 29.9k (marginally lower than the average benchmark impedance of 31.44k), the capacitor remains on par with the statistical benchmark across the majority of frequencies. For instance, the impedance of the GCM155R71H104KE02D at 100 kHz is calculated to be 16.42k, closely approximating the benchmark's average impedance of 16.07k.

By comparing the impedance performance of the Murata Electronics GCM155R71H104KE02D capacitor to the statistical benchmarks at both 1 Volt and 10 Volts, one can deduce that it mirrors the average impedance values across a range of test frequencies. Consequently, engineers can expect this capacitor to demonstrate consistent performance when integrated into their circuits alongside other comparable capacitors.

Capacitance

In this section, we will analyze the capacitance values of the GCM155R71H104KE02D capacitor, manufactured by Murata, by comparing them to the statistical benchmark data for capacitors with the same nominal value and type. This particular capacitor has a nominal capacitance of 100 nF, a tolerance of ±10%, and a voltage rating of 50V.

Upon examination of the component's performance at 1 Volt, we find that the measured series capacitance values closely match the average series capacitance values provided by the statistical benchmark data across all test frequencies. For instance, at 5 kHz, the series capacitance is almost identical, with the component measuring at 99.96 nF and the average benchmark value being 101.8 nF. Similar trends can be observed across other test frequencies, with variations that fall within the acceptable tolerance range of ±10%, confirming the reliability of the component's capacitance.

Similarly, when evaluating the performance of the GCM155R71H104KE02D capacitor at 10 Volts, the measured series capacitance values align fairly closely with their respective statistical benchmarks. It is worth noting that at lower test frequencies, the component demonstrates slightly higher capacitance values compared to the benchmark data. For example, at 10 kHz, the measured value for the component is 105 nF, while the maximum value recorded by the benchmark is 106.4 nF. This deviation, although small, could indicate that the capacitor's capacitance performance may be mildly influenced by the applied voltage and the frequency of operation.

Overall, the GCM155R71H104KE02D capacitor exhibits satisfactory performance when compared against the provided statistical benchmark data. The measured series capacitance values are within the acceptable tolerance, demonstrating that the component maintains stable capacitance across the tested frequency ranges. This stability is crucial for ensuring the reliable operation of electronic circuits and systems in which the capacitor is incorporated, providing consistent filtering, coupling, and energy storage capabilities.

Series Resistance

The GCM155R71H104KE02D exhibits a remarkable Series Resistance performance that outperforms the statistical benchmark's average values across test frequencies ranging from 5 to 600 kHz. For instance, at a test frequency of 5 kHz, the GCM155R71H104KE02D's Series Resistance is measured at 5.885k Ohms, which is significantly lower than the benchmark average of 8.751k Ohms. Similarly, at test frequencies of 50 kHz and 500 kHz, the component's Series Resistance values measure 556.1 Ohms and 61.36 Ohms, respectively—both considerably lower than the benchmark's average values of 865 Ohms and 91.81 Ohms.

When operating at 10 Volts, the GCM155R71H104KE02D continues to demonstrate exceptional Series Resistance levels, showing minimal deviation from the 1 Volt measurements. Test frequencies between 5 kHz and 600 kHz yielded a reduction in Series Resistance when compared to the benchmark. It is crucial to mention, however, that Series Resistance data is not available for test frequencies above 750 kHz with this specific component.

Overall, the GCM155R71H104KE02D showcases noteworthy performance in terms of its Series Resistance across various test frequencies, particularly when juxtaposed against the statistical benchmark data. This characteristic makes it a strong contender for engineers seeking high-performing capacitors for their circuits. Nevertheless, to develop a more comprehensive understanding of its performance at higher test frequencies, further testing and analysis would be necessary.

Dissipation Factor and Quality Factor

In this section, we will be examining the Dissipation Factor (Df) and Quality Factor (Q) performance of the GCM155R71H104KE02D capacitor against the statistical benchmark. The capacitor demonstrates a notably low Dissipation Factor across all test frequencies. With Df values ranging between 0.014 and 0.023, it indicates that very little energy is being lost or dissipated by the component. This low Df signifies efficient operation and minimal energy waste. Concurrently, the Quality Factor reinforces the component's excellent performance, with values ranging from 44.30 to 69.17. This superior performance identifies the GCM155R71H104KE02D capacitor as a high-quality component, suitable for circuits that demand minimal energy loss and maximum efficiency.

Next, we will discuss the LCR measurements at 10 Volts. Under these higher voltage conditions, the observed values for Df still remain comparatively low, ranging from 0.025 to 0.052. This indicates that the GCM155R71H104KE02D capacitor continues performing optimally even at increased voltage levels. The Quality Factor at 10 Volts ranges from 19.09 to 40.47. Although these Q values are lower compared to the 1 Volt test data, they are still noteworthy and suggest that the capacitor maintains reasonable performance across various voltage levels. It is important to note that data for test frequencies between 750 kHz to 1 MHz under 10 Volts is not available, which restricts our analysis for this particular voltage range.

To summarize, the low Dissipation Factor and appreciable Quality Factor exhibited by the GCM155R71H104KE02D capacitor highlights its effectiveness and efficiency for a broad range of applications where energy conservation and performance are critical. These factors should be taken into account by engineers and designers when integrating this capacitor into their electronic circuits and systems.
