Impedance

With a nominal capacitance value, 1μF, Samsung Electro-Mechanics' CL05A105MQ5NNNC features impedance characteristics that fluctuate across various test frequencies when measured at both 1 Volt and 6.3 Volts. Identifiable differences between the component's data and the average statistical benchmark provide insights into how this capacitor compares to competitors' offerings in terms of impedance performance across the frequency spectrum.

At lower frequencies of 5Hz and 10Hz, it's evident that the CL05A105MQ5NNNC's impedance values are significantly higher than the average statistical benchmarks provided for 1 Volt measurements: 36.33kΩ compared to 33.36kΩ and 18.26kΩ compared to 16.74kΩ, respectively. Nevertheless, as the test frequency increases, the discrepancy between the capacitor's impedance data and the average benchmark becomes less pronounced. This is distinguished at 100Hz where the CL05A105MQ5NNNC impedance value is 1.854kΩ as opposed to 1.702kΩ for the average counterpart.

Advancing into mid-frequency range, spanning from 500Hz to 20kHz, the CL05A105MQ5NNNC outperforms the statistical benchmarks. At 1kHz, Samsung's capacitor records an impedance value of 190Ω, which is lower than the 174.7Ω average. This trend continues at higher frequencies, such as 20kHz, where the CL05A105MQ5NNNC has an impedance value of 11.87Ω as opposed to the 10.88Ω average.

As we analyze the upper frequency range, from 50kHz to 1MHz, it is important to point out that the CL05A105MQ5NNNC impedance value closely aligns with, and sometimes surpasses, the statistical benchmarks. At 100kHz, the capacitor's impedance is measured at 2.631Ω, only slightly higher than the average of 2.408Ω. Moreover, when testing the component at its rated voltage of 6.3 Volts, analogous patterns arise, exhibiting minimal deviation from the capacitor's performance at 1 Volt. This observation implies that the CL05A105MQ5NNNC capacitor offers consistent impedance performance across a broad range of frequencies and various voltage conditions, showcasing the component's versatility and adaptability in real-world applications.

Capacitance

At 1 Volt, the CL05A105MQ5NNNC demonstrates a series capacitance of 877.2nF at 5Hz and 871nF at 1MHz. When comparing these values to the benchmark data, which showcases an average series capacitance of 962.5nF at 5Hz and 663.7nF at 1MHz, it is evident that the component performs below the benchmark at lower frequencies, yet exceeds the benchmark at higher frequencies. This behavior suggests that the capacitor may be less suited for applications requiring stable performance at lower frequency ranges. However, it's essential to assess this aspect based on the specific requirements of the intended application.

Moving on to higher frequency ranges, from 10kHz to 1MHz, the CL05A105MQ5NNNC exhibits improved performance. It surpasses the average benchmark values, demonstrating a consistent increase in capacitance as the frequencies progress. This range indicates the component's strength and potential for applications requiring higher frequency operations. Ensuring efficient performance in these higher frequency ranges is crucial in modern electronic components, as many devices now operate at frequencies within the order of kilohertz (kHz) to megahertz (MHz).

It is also essential to assess the behavior of the capacitor at various voltage ratings. At a voltage rating of 6.3 volts, the CL05A105MQ5NNNC reveals varied results. In the lower frequency range (5Hz - 1kHz), both minimum and maximum capacitance values remain below the benchmark, while staying well within the given tolerance. This suggests that the CL05A105MQ5NNNC is not as robust as other capacitors in this voltage range when it comes to low-frequency applications.

In the higher frequency range, the component showcases diminishing performance when compared to both the benchmark data and its own performance at 1 volt. The sharp decrease in capacitance from 1M (543.3nF at 6.3 Volts compared to 571nF at 1 Volt) warrants attention from engineers considering the usage of this component in their designs. Furthermore, it is crucial to consider various factors such as temperature, voltage stress, and physical size when determining the optimal capacitor choice for a specific application.

Series Resistance

The performance of Samsung Electro-Mechanics' CL05A105MQ5NNNC Ceramic: X5R Capacitor demonstrates higher series resistance values in comparison to the statistical benchmark data, particularly at lower test frequencies ranging from 5 to 50 Hz. For instance, at a frequency of 5 Hz, the component has a series resistance of 2.008 kOhms, which is significantly higher than the average benchmark value of 1.641 kOhms. However, as the test frequency increases beyond 50 Hz, the Series Resistance values start to become more comparable to the benchmark values, though still remaining marginally higher. For example, at a frequency of 100 Hz, the component has a resistance of 107.3 Ohms compared to the benchmark's average of 87.92 Ohms.

When looking at the 6.3V voltage range, the series resistance performance shows a similar pattern, with higher resistance values present at the lower tested frequencies. At 5 Hz, the component measures 2.142 kOhms, while at 10 Hz, it measures 1.025 kOhms. As the frequency increases, resistance values tend to converge with the benchmark values. However, there are still some isolated instances where the component's resistance value is higher than the benchmark data.

Considering these observations, the CL05A105MQ5NNNC Ceramic: X5R Capacitor exhibits a higher series resistance value, especially at lower test frequencies, in comparison to the statistical benchmark. This factor should be taken into account for specific applications that require lower series resistance values at lower operating frequencies. Nonetheless, the component can still be suitable for applications with operating frequencies higher than 50 Hz, as the series resistance values at these frequencies become relatively comparable to the benchmark data, indicating reasonable performance in such scenarios.

Dissipation Factor and Quality Factor

When analyzing the Dissipation Factor (Df) values of the CL05A105MQ5NNNC capacitor under 1 Volt and 6.3 Volts testing conditions, we observed an improvement in performance as the test frequency increased. At 1 Volt, the Df started at 0.055, eventually dipping to as low as 0.007 at 100 kHz, which indicates a higher efficiency capacitor as the frequency increases. This is primarily because a lower Df represents a lower energy loss during the charge-discharge process, resulting in improved capacitor performance. A similar trend was observed in test frequencies at 6.3 Volts, with the Df starting at 0.039 and reducing to an impressive 0.008 at 150 kHz.

In addition to the Df results, the CL05A105MQ5NNNC capacitor exhibited noticeable Quality Factor (Q) increases as the test frequency grew. The Quality Factor is an essential parameter highlighting the energy losses within a capacitor, with high Q signifying minimal losses. At the 1 Volt testing condition, the Q started at 18.06 (5 Hz) and increased significantly to 142.01 at 100 kHz. Similarly, at the 6.3 Volts, it started at 25.67 (5 Hz) and reached an impressive 121.52 at 150 kHz. This increase in Q values across frequencies emphasizes the enhanced performance this capacitor offers at higher frequencies.

It is crucial to consider the Dissipation Factor and Quality Factor while selecting capacitors for a specific application since these parameters directly affect the component's overall efficiency and frequency response. An excellent understanding of the frequency-dependent characteristics of capacitors will help ensure their optimal performance in accordance with the target application.
