Impedance

A thorough analysis of the Taiyo Yuden TMK212BJ475KG-T Capacitor's impedance performance at an array of frequencies reveals that it offers a reliable and consistent impedance at 1 Volt. It's worth noting that impedance plays a vital role in determining the effectiveness and overall appropriateness of a capacitor for electronic circuits.

At relatively lower frequencies such as 5 Hz and 10 Hz, the TMK212BJ475KG-T exhibits impedance values of 6.686k Ohms and 3.352k Ohms, respectively. Interestingly, these measurements exceed the corresponding average benchmark values. During the progression from 500 Hz to 1 kHz, the capacitor's impedance continues to surpass the benchmark average, measuring 71.15 Ohms and 36.81 Ohms, respectively.

This pattern of outperforming the statistical benchmark remains noticeable at higher frequencies. For example, at the 5 kHz mark, the capacitor's impedance reaches 7.863 Ohms, compared to the 7.722 Ohms benchmark average. Despite its upward trend, the TMK212BJ475KG-T's advantages gradually diminish across the entire frequency range.

When examining LCR measurements done at 10 Volts, the Taiyo Yuden capcitor showcases impressive results, outpacing average benchmarks throughout the frequency spectrum. A demonstration of its substantial performance can be observed at 5 Hz, registering an impedance value of 7.375k Ohms, a noteworthy increase from 6.686k Ohms at 1 Volt. Consequently, it displays excellent impedance at higher frequencies, such as 100 kHz, measuring 398.6m Ohms against the benchmark average of 492m Ohms.

In summary, the Taiyo Yuden TMK212BJ475KG-T Capacitor's impedance performance indicates reliability and consistency across a diverse frequency range. These characteristics underscore its suitability for various applications in electronic circuits, where stable impedance is crucial for optimal functionality and overall stability.

Capacitance

When examining the TMK212BJ475KG-T capacitor's performance against a statistical benchmark, its behavior appears to be quite distinctive. At 1V across a wide range of test frequencies, the results indicate that this component offers contrasting performance characteristics when compared to the benchmarks' average series capacitance values. In the lower frequency region, specifically from 5Hz to 100Hz, the capacitor's series capacitance is considerably higher, thus implying superior performance. For instance, at 50Hz, it measures 4.695μF as opposed to the 5.029μF benchmark average value. On the contrary, the capacitor exhibits above-average capacitance in the 450kHz - 600kHz range. At 600kHz, the measured capacitance for the Taiyo Yuden's component is 4.044μF, significantly lower than the 27.72μF value observed in the statistical benchmark.

In addition, the TMK212BJ475KG-T's performance profile takes an interesting turn when evaluated at 10V. In the 5Hz to 100kHz range, the component consistently falls short of the statistical benchmark's average capacitance values. However, the capacitor outperforms the benchmark once again in the 300kHz - 450kHz range, making it a viable option for certain applications that demand enhanced high-frequency performance.

These performance fluctuations call for a deeper analysis when considering the TMK212BJ475KG-T capacitor's integration into various electronics systems. Although the component demonstrates some promising advantages at specific test frequencies and applied voltages, it fails to consistently maintain above-average performance when contrasted with the statistical benchmark consisting of similar value capacitors. A comprehensive understanding of these performance characteristics is crucial because they can profoundly influence the overall performance of an electronic system, depending on the target application's demands and specific product requirements.

Series Resistance

When evaluating the Taiyo Yuden TMK212BJ475KG-T capacitor, its series resistance performance is observed at different test frequencies. At lower test frequencies (e.g., 5Hz), the TMK212BJ475KG-T shows a series resistance of 221.2 Ohms, which is below the average (252 Ohms) and significantly lower than the maximum benchmark series resistance of 548.1 Ohms. These lower series resistance values contribute to reduced power losses and improved efficiency in electronic circuits.

As the test frequency increases (10Hz), its series resistance falls to 105.6 Ohms, remaining well below the average benchmark value (125.4 Ohms) and the maximum (283 Ohms). This trend of below-average series resistance values sustains as the test frequency continues to rise, making this capacitor ideal for use in circuits operating at higher frequencies.

At test frequencies of 1 kHz and beyond, the series resistance of this capacitor drops dramatically, with its performance becoming markedly superior to the benchmark values. For instance, at 1 kHz, the Taiyo Yuden TMK212BJ475KG-T exhibits an 834.2 mOhms series resistance, which is significantly lower than the benchmark average (1.348 Ohms). This low series resistance further helps in reducing the effects of parasitic resistances in circuits and improving the component's overall performance and efficiency.

For those considering this capacitor for use in their circuits, it is worth noting that its series resistance value remains below the average benchmark values at all test voltages and frequencies. This aspect positions the TMK212BJ475KG-T capacitor as a contender for solid performance in a variety of applications, particularly at higher frequencies. In addition, the consistently low series resistance exhibited by this component offers better power-handling capabilities, contributing to increased reliability and versatility in its usage.

Dissipation Factor and Quality Factor

The Taiyo Yuden TMK212BJ475KG-T capacitor demonstrates excellent performance in relation to its low dissipation factor (Df) and high quality factor (Q) across various test frequencies. When assessing the outcomes at 1 Volt, it is observed that the TMK212BJ475KG-T's minimum Df measures 0.022 at a 1kHz test frequency. It should also be highlighted that the Df becomes more prominent with the increase of test frequencies. This behavior is consistently observed when evaluating the measurements at 10 volts, where the capacitor's performance is more remarkable at lower test frequencies. Notably, a Df of 0.054 at 5 Hz and 0.050 at 10 Hz yields favorable comparison with the statistical benchmark data concerning energy efficiency.

Regarding the quality factor (Q), the Taiyo Yuden capacitor reaches an exceptional peak of 88.15 Q value at a 10kHz test frequency while measured at 1 Volt; this high Q value represents outstanding efficiency in energy storage. Nevertheless, it is essential to consider that the Q value tends to deviate as test frequencies increase, resulting in diminished Q values at those elevated frequencies. When examining the measurements at 10 Volts, the Q value soars to a striking peak of 2833.20 at a 75kHz test frequency, surpassing the performance of most capacitors present within the statistical benchmark. As a result, opting for this capacitor proves advantageous in applications necessitating stable energy storage at particular frequencies, as it offers excellent performance in terms of dissipation and quality factors.
