Introduction

In this technical review, we will examine the Samsung Electro-Mechanics CL31B475KAHNNNE, a ceramic X7R surface mount capacitor with a nominal value of 4.7μF, ±10% tolerance, and a 25V voltage rating in a 1206 (3216 Metric) package. Our analysis will benchmark the performance of this capacitor against the statistical benchmark data composed of similar value capacitors. Based on the provided LCR measurements, we can evaluate important parameters like capacitance, series resistance, dissipation factor, and quality factor.

Pros:

• Wide range of operating frequencies
• 4.7μF nominal value provides a versatile option in circuits
• Positive quality factor trend across test frequencies
• Generally stable capacitance values for low to mid-test frequencies

• Higher dissipation factor compared to benchmark performance, especially at high test frequencies

Impedance

In this section, we will analyze the impedance of the Samsung Electro-Mechanics CL31B475KAHNNNE Capacitor by comparing it with statistical benchmark data from capacitors of the same value. Impedance is an essential parameter to consider when selecting a suitable capacitor for various applications, as it influences the overall performance, efficiency, and stability of a system.

Overall, the CL31B475KAHNNNE Capacitor shows a higher impedance value across most of the test frequencies, ranging from 5 Hz to 1 MHz, as compared to the average impedance of the statistical benchmark at 1V test voltage. At 5 kHz frequency, for example, the CL31B475KAHNNNE exhibits an impedance of 8.072 Ohms, while the average impedance for components in the benchmark is 7.722 Ohms. This higher impedance trend continues across other test frequencies, such as at 1 kHz, where the component measures 38.3 Ohms as opposed to the benchmark's average impedance of 35.31 Ohms.

Further examination of the data reveals that not just the average but also the minimum and maximum impedance values from the benchmark data outperform the CL31B475KAHNNNE Capacitor. This indicates that there may be alternative capacitors available in the market that can provide lower impedance values and could potentially be a better fit for applications that demand lower impedance components. One such example can be observed at 50 kHz, where the component registers an impedance of 838.1 mOhms, while the minimum impedance in benchmark data is 666.4 mOhms.

However, when testing at 10V test voltage, the capacitor's impedance values seem to hover closer to the benchmark. For instance, at 10 kHz, the component measures 3.851 Ohms impedance, which is nearer to the benchmark's average impedance of 3.987 Ohms.

From the above analysis, it is evident that the Samsung Electro-Mechanics CL31B475KAHNNNE Capacitor exhibits higher impedance values for most of the test frequencies when compared to the statistical benchmark at 1V test voltage. In applications where low impedance is not vital, the CL31B475KAHNNNE Capacitor may serve as a suitable option. However, for applications where lower impedance components are a requirement, it would be prudent to explore alternatives that may be closer to the benchmark values. Moreover, it is essential to consider that the actual impedance performance in a specific circuit may vary due to factors such as layout, temperature, underlying load conditions, and varying source voltages, which requires careful attention during the selection process.

Capacitance

At 1 Volt, the CL31B475KAHNNNE capacitor exhibits a series capacitance ranging from 4.524μF at 5 Hz to 4.891μF at 1 MHz. Notably, compared to the benchmark data, these values underperform compared to the average values in the same frequency ranges. However, the component does perform consistently within the tolerance threshold, as its 4.7μF nominal value with a ±10% tolerance spans between 4.23μF and 5.17μF.

Upon further analysis, at a test frequency of 50 kHz, the CL31B475KAHNNNE outperforms the minimum series capacitance benchmark of 2.885μF with a measured value of 3.797μF. Nonetheless, it falls short of the average benchmark value of 3.95μF and the maximum of 4.777μF. This trend persists throughout the remainder of the tested frequencies, suggesting that while it does not excel in comparison to the benchmark, it encompasses a reasonable range.

Testing the CL31B475KAHNNNE at 10 Volts showcases an interesting deviation from the benchmark. The series capacitance in the event of higher voltage testing ranges from 4.875μF at 5 Hz to an exceptional 5.201μF at 700 kHz. While these measurements slightly surpass the previously mentioned tolerance threshold, they significantly outperform the benchmark data, demonstrating how the CL31B475KAHNNNE's capacitance is influenced by increased voltage application. This insight is important for engineers requiring components with specific capacitance behavior under higher voltage conditions.

Overall, when taking into account both the voltage-dependent characteristics and the broader performance against the benchmark data, the Samsung Electro-Mechanics CL31B475KAHNNNE capacitor demonstrates consistent stability within its specified tolerance limits. Although lacking in comparison to the average benchmark values, potential applications may find benefit from its performance in particular conditions. Engineers should carefully consider the applied voltage and desired frequency range in relation to its limitations and deviations before deciding on its suitability for their specific circuits, taking into account the impact of voltage on capacitance behavior and stability for optimal performance.

Series Resistance

The CL31B475KAHNNNE capacitor by Samsung Electro-Mechanics exhibits substantially improved series resistance performance across most of the test frequency range at a 1V applied voltage, compared to the benchmark data. Significant improvements can be observed at frequencies between 100Hz and 1MHz. At 100Hz, the CL31B475KAHNNNE offers up to 30.74% lower average series resistance with a reported value of 13.82 Ohms. As the frequency increases, for example at 500kHz, the series resistance measurements of this particular capacitor are reported to be 36.32% lower, measuring at 9.301m Ohms, as compared to the benchmark value of 1.459 Ohms.

When subjected to a 10V applied voltage, the CL31B475KAHNNNE capacitor demonstrates varied results in terms of series resistance compared to the benchmark data. In the frequency range of 5Hz to 100kHz, the CL31B475KAHNNNE generally maintains its enhanced performance with lower average series resistance values. For example, at 50Hz, this capacitor's value is reported to be 26.36 Ohms, which is significantly lower than the benchmark value of 63.24 Ohms. However, in the frequency range of 150kHz and above, the series resistance of the CL31B475KAHNNNE tends to deviate from the benchmark data, sometimes falling outside the acceptable range.

In summary, the Samsung Electro-Mechanics' CL31B475KAHNNNE capacitor offers an impressive performance in terms of series resistance at a 1V applied voltage while delivering mixed results at a 10V applied voltage. When operating in higher frequencies and 10 Volts, it is crucial to closely compare the measurements to the benchmark data, ensuring the capacitor's performance meets the specific requirements of the intended application. By doing so, engineers can make well-informed decisions about the suitability of this capacitor to their designs and optimize the overall performance of electronic devices.

Dissipation Factor and Quality Factor

When examining the characteristics of Samsung Electro-Mechanics' CL31B475KAHNNNE Ceramic: X7R capacitor, it becomes crucial to pay attention to the dissipation factor (Df) and quality factor (Q). Ideally, a capacitor should exhibit a low Df and a high Q, which result in energy-efficient performance, minimized losses in electronic circuits, and improved operational reliability. These factors make Df and Q critical parameters for electronics engineers when evaluating this component.

Upon scrutinizing the LCR measurements for the CL31B475KAHNNNE capacitor at a test signal of 1 volt, we observe that the Df ranges from 0.026 at a low frequency of 5 Hz to 0.244 at a considerably higher frequency of 1 MHz. This capacitor manifests exceptional performance, especially when operating at frequencies of 1 kHz and higher, maintaining Df values below 0.05 up to 150 kHz and resulting in high Q values. For example, at 5 kHz and 10 kHz, the Q values are recorded at 67.03 and 69.06, respectively, which are notably higher than those of comparable components available in the market.

Similar observations can be drawn when assessing the LCR measurements recorded at 10 volts, with Df values ranging from 0.041 at a low frequency of 5 Hz to non-detectable levels at higher frequencies. In particular, this capacitor displays outstanding Q performance at higher frequencies and voltage levels. At 150 kHz and 200 kHz, for instance, Q values reach 210.15 and 198.85, respectively, both substantially higher than the benchmark values. This highlights the component's potential in specialized applications, especially those that require higher voltage ratings.

In summary, the CL31B475KAHNNNE capacitor from Samsung Electro-Mechanics exhibits low Df and high Q characteristics, particularly when operating at higher frequencies and voltage levels. These features make it a strong contender for electronics engineers searching for a Ceramic: X7R capacitor that provides reliable, energy-efficient performance when incorporated into their electronic systems and designs.
