Impedance

In this technical review, we examine and compare the impedance performance of Murata Electronics' GCM155R71H104KE02J capacitor to its statistical benchmark. Impedance is a critical parameter for capacitors, as it affects their ability to store and release energy in a circuit, as well as filter out unwanted signals. Consequently, capacitors with lower impedance values are typically preferred, as they offer better performance in applications such as power supply filtering and decoupling.

At a test voltage of 1 V, the GCM155R71H104KE02J capacitor demonstrates competitive impedance results when compared to its statistical benchmark. The component consistently exhibits impedance values that are either in line with or slightly lower than the benchmark's average across a wide range of testing frequencies. Some specific examples include test frequencies at 50 kHz, 200 kHz, and 800 kHz, where the impedance values for the GCM155R71H104KE02J were 31.3k, 8.609k, and 2.188k ohms compared to the benchmark's average of 31.67k, 9.318k, and 2.434k ohms, respectively.

Similar impedance performance was observed at a higher test voltage of 10 V. At this voltage level, the GCM155R71H104KE02J capacitor delivers impedance values that are comparable to or lower than the established benchmark. Test frequency examples at this voltage include 50 kHz, 200 kHz, and 600 kHz, where the component impedance values were measured at 29.19k, 8.312k, and 2.887k ohms, while the benchmark averages were 31.67k, 9.318k, and 3.225k ohms, respectively.

It is important to note that impedance values are tied not only to the capacitor's inherent properties but also to frequency levels. Different applications may require different frequency bands to be considered, so it's essential to examine the full range of impedance performance.

In conclusion, the impedance performance of Murata Electronics' GCM155R71H104KE02J capacitor is well-aligned with or surpasses its provided statistical benchmark. This makes it a competitive choice for various applications where reliable impedance characteristics are crucial, such as power supply filtering and decoupling, as well as signal processing in communication systems.

Capacitance

In this section, we will discuss the performance of the GCM155R71H104KE02J capacitor by examining its capacitance values. This capacitor has a nominal capacitance of 100nF (0.1μF) and a voltage rating of 50 volts. High capacitance retention across various frequencies and voltages is essential for stable performance, especially in applications requiring filtering, decoupling, or energy storage functions.

We'll assess this component's performance by comparing the measured capacitance values at both 1V and 10V to the given statistical benchmark data for capacitors with the same nominal value. The GCM155R71H104KE02J capacitor consistently maintains a capacitance value above the average at all test frequencies and voltage ratings. For instance, at a test frequency of 5Hz and 1V test voltage, the measured capacitance is 102.5nF, while the average benchmark capacitance is 101.8nF. Similarly, at 100kHz test frequency, the measured capacitance value remains above the average value (93.61nF and 88.4nF, respectively).

This trend is consistent even when the test voltage is increased to 10V. The GCM155R71H104KE02J capacitor achieves an impressive performance by consistently maintaining capacitance values well above the average at higher test frequencies. This is particularly noteworthy at test voltages of up to 500kHz, where maintaining stable capacitance values can be challenging due to parasitic effects such as equivalent series resistance (ESR) and equivalent series inductance (ESL).

Overall, the GCM155R71H104KE02J capacitor demonstrates high capacitance retention across a wide range of frequencies and voltages, showcasing its robust and consistent performance. This makes it a reliable choice for circuits requiring a ceramic, X7R capacitor with stable capacitance characteristics, which ensures the proper functioning of devices, especially in environments with fluctuating temperatures and voltage conditions.

Series Resistance

When evaluating the GCM155R71H104KE02J capacitor's series resistance performance, it is essential to compare it to the statistical benchmark data for capacitors with the same capacitance value. The series resistance of a capacitor is crucial because it affects the component's efficiency and power dissipation capabilities.

At a 1 Volt test voltage, the GCM155R71H104KE02J's series resistance was generally lower than the average series resistance of the benchmark data, particularly in the frequency range between 100 Hz and 20 kHz. However, beyond 50 kHz, the series resistance displayed a peculiar behavior where it increased, moving closer to the benchmark average before decreasing again and remaining below average from 550 kHz to 1 MHz. This deviation may indicate a possible area for improvement in the component's design or manufacturing process, although it might not have a significant impact on specific applications.

At a higher test voltage of 10 Volts, the GCM155R71H104KE02J capacitor displayed higher series resistance values than the benchmark, particularly prominent in the 5 Hz to 50 kHz range. The series resistance then decreased and remained below average from 150 kHz to 1 MHz. This change suggests that the component may exhibit a nonlinear response to different operating voltage levels, which could have implications for its suitability in voltage-sensitive applications.

While the GCM155R71H104KE02J does not always match or outperform the statistical benchmark across all test frequencies, it demonstrates reliable and consistent series resistance characteristics that could be suitable for specific applications. However, it is crucial for potential users to examine carefully the component's series resistance data in relation to their desired performance requirements to make the most informed decision on whether this Ceramic: X7R capacitor will meet their expectations. It is also important to consider other factors, such as physical size constraints, temperature stability, and overall system design requirements, to ensure the best-fit capacitor for the intended application.

Dissipation Factor and Quality Factor

The GCM155R71H104KE02J, when tested at a 1 Volt measurement, exhibits a relatively low dissipation factor (Df), ranging between 0.014 and 0.020 across test frequencies from 5 Hz to 1 MHz. These low values suggest low energy loss in the form of heat, providing better efficiency. Additionally, its quality factor (Q factor), which represents the ratio of energy stored to energy dissipated, varies between 55.39 and 72.80, showcasing a high-performance quality compared to the benchmark. It's worth noting that the Q factor reaches its peak of 73.28 at a frequency of 200 kHz, indicating excellent performance in that particular frequency range.

When the voltage increases to 10 Volts, the dissipation factor experiences a slight uptick while maintaining relatively low levels, with values between 0.023 and 0.053 across the tested frequencies. As a result, the quality factor experiences a minor decline, showing values that range from 19.00 to 43.67. However, the capacitor continues to display strong performance within specific frequency ranges – for example, the Q factor reaches a peak of 42.51 at a frequency of 500 kHz. Understanding the relationship between dissipation and quality factors across varying voltage levels and frequencies is crucial for proper component selection to meet desired performance requirements in electronic circuit applications.
