Impedance

The KYOCERA AVX 08055C104KAT2A demonstrated varying impedance values across a range of frequencies at both 1V and 10V test conditions. At 1V, the impedance measurements ranged from 315.1k Ohms at 5Hz to 1.765k Ohms at 1MHz; meanwhile, the 10V measurements ranged from 253.7k Ohms at 5Hz to 1.06k Ohms at 1MHz. Generally, the 08055C104KAT2A displayed higher impedance values at lower test frequencies and lower impedance values at higher test frequencies – a typical characteristic behavior of capacitors.

Upon comparing the 08055C104KAT2A's impedance performance with the statistical benchmark data, it is apparent that at 1V test conditions, the capacitor's impedance falls within the benchmark range for the majority of frequencies. However, it is essential to note that the capacitor's impedance at lower frequencies (specifically between 5Hz and 10Hz) tends to be slightly higher than average values. Conversely, at higher frequencies above 100kHz, the 08055C104KAT2A exhibits somewhat lower impedance compared to the benchmark average values. Thus, in applications that require lower impedance at higher frequencies, the 08055C104KAT2A may prove to be a more suitable choice amongst capacitors with the same value.

Similar performance trends can be observed under the 10V test conditions, with the 08055C104KAT2A generally maintaining impedance values within the benchmark range across various frequencies. Nevertheless, it is important to emphasize that the impedance values deviate more significantly from the benchmark average at higher frequencies, ranging from 15.78k Ohms at 100kHz to 1.06k Ohms at 1MHz. This considerable deviation suggests that the 08055C104KAT2A may be preferred in applications that demand lower impedance values at high frequencies. Furthermore, understanding these trends allows engineers to make better-informed decisions when selecting capacitors for specific applications, ensuring optimal performance and reliability.

Capacitance

An in-depth evaluation of KYOCERA AVX's 08055C104KAT2A Ceramic X7R multilayer capacitor requires a thorough examination of its capacitance values across a wide range of test frequencies. By comparing its performance to the statistical benchmark data of similar components, users can better understand the capabilities of this capacitor and determine if it satisfies their specific needs.

Upon analysis, the 08055C104KAT2A displays impressive capacitive behavior at 1 Volt. Its performance closely aligns with the benchmark average for various test frequencies and consistently exceeds the minimum capacitance values. For instance, when tested at a frequency of 50kHz, the capacitor's measured series capacitance registers at 100.1nF, which is quite close to the average value of 100.7nF. Furthermore, the 08055C104KAT2A delivers higher capacitance values at lower frequencies, such as a reported 101nF at 5kHz compared to the average of 101.8nF.

This trend of surpassing the minimum and, at times, average capacitance values is apparent across all test frequencies, with the 08055C104KAT2A outperforming the average series capacitance up to the 1MHz mark. Notably, the component's capacitance values display minimal variation while staying consistent even as test frequencies escalate.

In comparison to the statistical benchmark data at 10 Volts, the 08055C104KAT2A continues to exhibit strong performance across all test frequencies. The component's measured series capacitance values increase considerably at higher voltage levels, such as the 125.7nF reading at 5kHz in contrast to the 101nF measurement at 1 Volt. This enhanced capacitance stability at a broader voltage range is evident throughout the entire test frequency spectrum, indicating that the 08055C104KAT2A is highly effective at maintaining its capacitance stability under various operating conditions.

Series Resistance

When analyzing the series resistance of the 08055C104KAT2A Capacitor at 1 Volt, it is essential to consider its performance across a wide range of frequencies. It is observed that the component exhibits varying resistance values depending on the frequency at which it is tested. An important aspect to note is that at lower frequencies, the series resistance of the capacitor tends to be higher than the statistical benchmark.

For instance, at 5 Hz, the component presents a series resistance of 5.222k Ohms, considerably lower than the benchmark's average value of 8.751k Ohms. Similarly, at 10 Hz, the component's series resistance comes in at 2.527k Ohms, compared to the benchmark average of 4.329k Ohms. This pattern of the capacitor exhibiting lower resistance values relative to the benchmark persists across the entire frequency spectrum.

In contrast, the 08055C104KAT2A Capacitor's performance in terms of series resistance tends to improve at higher frequencies when compared to the benchmark. For example, at 1 MHz, the component registers a series resistance of 62.67m Ohms, which is lower than the benchmark's average value of 70.07m Ohms. This progressive improvement in performance as the frequency increases should be an influential factor for engineers when selecting suitable components for their designs.

Upon examining the 10-volt LCR measurements, it is evident that the 08055C104KAT2A Capacitor bears similar results, showcasing lower resistance values than the statistical benchmark across the entire frequency range. This consistency in the component's performance implies that its operating voltage does not significantly affect the resistance behavior, which can be a valuable consideration for engineers working with varying voltage conditions.

Dissipation Factor and Quality Factor

The 08055C104KAT2A capacitor demonstrates a variety of dissipation factors (Df) and quality factors (Q) at varying voltages and frequencies. Such factors provide insights into the energy loss and overall efficiency of the capacitor.

At the 1V voltage level, the dissipation factor ranges from 0.015 to 0.036, while the quality factor spans from 28.24 to 65.43. The lowest dissipation factor of 0.015 occurs at 50 Hz, making this capacitor a suitable choice for low-frequency applications. Throughout the 1V frequency spectrum, the capacitor's performance remains fairly consistent, with only minor fluctuations in Df and Q values.

Conversely, performance at 10V displays more significant discrepancies. At voltage levels from 50 Hz to 1 MHz, the Df varies from 0.030 to 0.068, and the Q from 14.70 to 34.30. A noteworthy observation is that maximum Q is achieved at a substantially lower frequency of 250 kHz. Despite these variations, the Df remains relatively low, and the Q remains relatively high across all 10V frequencies, demonstrating the capacitor's stable performance.

Comparing these findings to benchmark data reveals that the 08055C104KAT2A capacitor exhibits moderate performance. At lower voltages, the Df and Q values are adequate but could benefit from enhancement. Conversely, at higher voltages, the Df and Q exhibit more substantial fluctuations but maintain acceptable ranges, ensuring consistency in the capacitor's performance.

If further improvements to the Df and Q factors are desired in specific applications, exploring alternative capacitors with enhanced characteristics may be advantageous.

Upon comparing the measured LCR values of the 08055C104KAT2A at both 1V and 10V test frequencies with the statistical benchmark data, it becomes evident that the capacitor's performance is closely aligned with the average values across most of the sections analyzed. For instance, its impedance, series resistance, and series capacitance largely fall within the benchmark's average range, suggesting that the component's overall performance and reliability can be considered on par with other similar parts.

However, a thorough analysis of the capacitor's dissipation factor and quality factor measurements reveals certain differences. While the 08055C104KAT2A's dissipation factor is consistently higher than the average benchmark values at both 1V and 10V test frequencies, its quality factor is slightly lower than the benchmark's average values across the tested frequency range. This observation suggests that this particular capacitor may exhibit slightly greater energy dissipation and lower frequency stability compared to other capacitors in the Ceramic: X7R category.

In conclusion, the KYOCERA AVX 08055C104KAT2A Capacitor provides a reasonable performance that meets industry benchmarks for most of the analyzed sections. However, careful consideration should be given to its somewhat higher dissipation factor and lower quality factor, which may impact certain applications. However, depending on the requirements of a specific application, the capacitor could still potentially serve as a reliable and competitive choice for engineers seeking a Ceramic: X7R component for use in their products.
