Impedance

The Würth Elektronik capacitor, part number 885012108012, was evaluated for its impedance performance by comparing it to available benchmark data for similar X5R capacitors with a 47μF capacitance value. The impedance results of this capacitor were examined at two different voltage levels: 1 Volt and 10 Volts.

At 1 Volt, the capacitor demonstrates an impedance of 701.1 Ohms at a 5 Hz test frequency, which is proximate to the maximum value observed in the statistical benchmark (783 Ohms). As the test frequency increases to 10 Hz, the impedance value decreases to 352.1 Ohms, positioning it between the average and maximum benchmark impedance values of 332.8 Ohms and 393.7 Ohms, respectively. An analysis of the impedance values at higher frequencies, such as 100 kHz and 1 MHz, reveals that these values are consistent with the benchmark data. Notably, the capacitor presents relatively low impedance at 1 MHz, with a recorded value of 10.06 milliOhms.

When the voltage is increased to 10 Volts, measured impedance values maintain consistency with the benchmark data in the tested frequency range (5 Hz to 500 kHz). At lower frequencies, the impedance performance closely aligns with the benchmark values. For instance, at 10 Hz, the measured impedance was 533.6 Ohms, while the statistical benchmark range spans 295.5 - 393.7 Ohms. As the frequency increases, the capacitor's impedance tends to match or even surpass the benchmark averages, as observed at 10 kHz, 20 kHz, and 50 kHz. This phenomenon is particularly evident in the 100 kHz range, where the capacitor exhibits an impedance value of 47.22 milliOhms, exceeding the average benchmark value (35.77 milliOhms).

Overall, the impedance performance of Würth Elektronik's 885012108012 ceramic X5R capacitor aligns consistently with the statistical benchmark data at both 1 Volt and 10 Volts. Although some recorded values deviate from the averages, they mostly remain within the expected range, considering the minimum and maximum statistics. Consequently, this capacitor can serve as a dependable component for engineers designing circuits that necessitate stable impedance across a broad frequency spectrum. However, if applications require precise impedance values at specific frequencies, further investigation and comparison with alternate capacitors are recommended.

Capacitance

An in-depth examination of the capacitance performance of Würth Elektronik's 885012108012 capacitor in relation to the statistical benchmark data for Ceramic: X5R capacitors requires analyzing its behavior at different frequencies and voltages. This involves comparing its measured results against the minimum, average, and maximum values of Series Capacitance held by the statistical benchmark, which serves as a well-established reference.

Upon conducting measurements at 1 Volt, the 885012108012 capacitor exhibits Series Capacitance values that oscillate around the average values of the statistical benchmark, predominantly up to 400 kHz. At lower frequencies (50 Hz - 1 kHz), the capacitor's capacitance is observed to maintain higher values than the benchmark's average, but this advantage diminishes as the frequency increases beyond 1 kHz. Interestingly, at 700 kHz, the capacitor reaches an impressive capacitance of 18.56m Farads, dramatically surpassing the benchmark's average of 1.456m Farads at the same frequency. This notable achievement reflects positively on the capacitor's performance at higher frequencies.

Moving forward, LCR measurements at 10 Volts reveal that the 885012108012 capacitor showcases greater stability within the performance range of the statistical benchmark. Between 10 Hz and 1 kHz, the capacitor's capacitance sustains values that are consistently above the benchmark's average. However, as the frequency rises to 5 kHz and beyond, the capacitance gradually falls below the benchmark's average. Mirroring its behavior at 1 Volt, the capacitor once again outperforms the benchmark with an impressive capacitance of 549.1μ Farads at 500 kHz, completely outshining the statistical benchmark's maximum value of 125.5μ Farads at the same undertaking.

In summary, the 885012108012 capacitor exhibits relatively stable performance across various frequencies and voltage ratings, with the notable presence of occasional exceptional capacitance peaks at higher frequencies. Although it demonstrates a few deviations from the statistical benchmark, particularly at elevated frequencies, the capacitor still delivers a competitive capacitance. These factors make the Würth Elektronik 885012108012 capacitor an attractive choice for engineers seeking high-performing Ceramic: X5R capacitors for their designs, giving them confidence in the effectiveness and reliability of the component.

Series Resistance

In this review, we explore the series resistance performance of Würth Elektronik's 885012108012 capacitor and compare it to statistical benchmark data to gain insight into its effectiveness. The analysis will mainly focus on the component's series resistance characteristics under specific test conditions, namely at 1 Volt and 10 Volts test voltage levels.

At a 1 Volt test condition, the 885012108012 capacitor demonstrates impressive performance compared to the benchmark. For instance, at the 1 kHz test frequency, this capacitor's series resistance is measured at 112.8m Ohms, which is significantly lower than the benchmark average of 437.4m Ohms. This favorable comparison remains consistent across other test frequency ranges, such as 100 Hz and 10 kHz, where the 885012108012 surpasses the benchmark data with series resistance values of 1.871 Ohms and 14.67m Ohms, respectively, indicating its superior performance.

When increasing the test voltage to 10 Volts, the component maintains its superior performance when compared to the benchmark data for frequencies like 5 Hz and 10 Hz. At these respective frequencies, the series resistance of the capacitor registers at 73.08 Ohms and 43.78 Ohms, outperforming the benchmark. It is important to note, however, that at higher test frequencies, such as 50 kHz, the available data becomes less copious, with missing values for both the 885012108012 capacitor and the benchmark set. In-depth measurements and comparisons at higher frequencies are hindered due to these data limitations.

Overall, the analysis of series resistance performance at different test voltages and frequency ranges allows us to gain a comprehensive understanding of the Würth Elektronik 885012108012 capacitor. From this knowledge, we can conclude that this component consistently outperforms the benchmark data and exhibits promising characteristics in various applications where low series resistance is a critical factor.

Dissipation Factor and Quality Factor

The 885012108012 capacitor demonstrates varying dissipation factor (Df) and quality factor (Q) values across different voltage levels and frequencies. At a voltage level of 1 Volt, the capacitor exhibits relatively low Df values from 5 Hz to 5 kHz, ranging from 0.022 to 0.053. These low values are advantageous because they signify reduced energy dissipation and a lower temperature rise in the capacitor. The Q factor values in this range are modest, staying between 19.02 at 5 Hz and 44.86 at 5 kHz. The Q factor is a dimensionless parameter obtained by dividing the reactance by resistance, reflecting the efficiency of the energy storage and return process in the capacitor.

At higher frequencies, however, Df and Q values for the 885012108012 capacitor change considerably. Df values increase significantly, reaching up to 8.634 at 650 kHz. This increase leads to a substantial decrease in Q values, with a minimum value of 0.12 at 650 kHz. Higher Df values at high frequencies indicate increased energy loss, and the reduced Q factor signifies diminished energy storage efficiency.

When testing at 10 Volts, the capacitor maintains low Df values up to 1 kHz, ranging from 0.054 to 0.082. The Q factor values within the 5 Hz to 1 kHz range are moderate, lying between 12.16 and 18.41. At 10 kHz, an exceptional Q value of 952.66 is observed, accompanied by a minimal Df value of 0.001. This data point differs significantly from the rest of the results, and the high Q value indicates excellent energy storage efficiency at this specific frequency. However, similar to the 1 Volt tests, the capacitor's performance at higher frequencies is characterized by increased Df values and significantly lowered Q factors.

These findings allow a nuanced understanding of the 885012108012 capacitor's performance in terms of energy loss and storage efficiency across different voltage levels and frequencies. While its low-frequency performance shows promise, its high-frequency behavior suggests room for improvement.
