Impedance

Upon evaluating the LCR Measurements of the 0805ZD476MAT2A Capacitor at 1 Volt, it can be observed that this component offers a comparable impedance performance with the statistical benchmark. It is essential to highlight that impedance is a crucial parameter for capacitors in determining how much opposition they provide to alternating currents (AC) at various frequencies. Lower impedance values are generally sought to minimize signal losses and allow smooth operation in high-frequency applications.

At test frequencies of 5 Hz, 10 Hz, and 50 Hz, the 0805ZD476MAT2A Capacitor exhibits slightly higher impedance values compared to the benchmark. However, as the test frequency increases from 100 Hz to 1 MHz, this capacitor maintains its stability and consistency in terms of impedance performance. This is an essential characteristic for applications requiring reliable performance over a wide frequency range.

At the wider voltage range of 10 Volts, a similar trend in impedance performance can be seen. Noticeably, the 0805ZD476MAT2A Capacitor demonstrates higher impedance across lower test frequencies compared to the benchmark. Nonetheless, it gradually stabilizes within the range of 100 Hz to 1 MHz, maintaining proximity to the statistical benchmark. This stability in impedance performance over various voltage levels contributes to the reliability and versatility of the capacitor in numerous applications, such as filtering, power regulation, and decoupling in different electronic circuits.

Capacitance

In this section, we will discuss the capacitance performance of the KYOCERA AVX 0805ZD476MAT2A Ceramic: X5R capacitor and compare its performance to benchmark data obtained from similar capacitors with the same nominal value. This analysis enables us to understand how the 0805ZD476MAT2A capacitor compares to capacitors typically used in electronic circuits and helps identify any potential limitations or areas where caution is necessary.

Starting with the LCR (Inductance, Capacitance, Resistance) measurements at 1V, we can observe that the 0805ZD476MAT2A capacitor displays a series capacitance of 44.09μF at 5 Hz, placing it near the average value of 49.2μF within the statistical benchmark. As the test frequency is increased, the series capacitance decreases gradually, recording values of 34.58μF and 34.09μF at 5 kHz and 10 kHz, respectively. Compared to the benchmark values of 38.46μF at 5 kHz and 37.07μF at 10 kHz, the 0805ZD476MAT2A falls within an acceptable range, showcasing good performance at the tested frequencies.

However, we notice a prominent discontinuity in the capacitance performance as the test frequency increases from 600 kHz up to 800 kHz. The measurement shows a significant spike in the series capacitance, with values ranging from 83.71μF to as high as 998μF. This deviation is noteworthy, as it considerably surpasses the benchmark values typically seen at the same test frequencies. Meanwhile, at 1 MHz, the series capacitance for the component sharply drops to 1.563μF, dramatically exceeding the benchmark value of 345.5μF. This potentially represents a frequency-dependent limitation within the tested capacitance range.

When assessing the LCR measurements at 10 V, the 0805ZD476MAT2A capacitor yields an initial series capacitance of 17.01μF at 5 Hz, which is nearly three times smaller than the starting value recorded at 1 V. While most of the capacitance values within the lower test frequency range stay relatively close to the benchmark data, there is a stark deviation when the test frequency exceeds 450 kHz. At 500 kHz, we observe a considerable capacitance spike, reaching an astounding 13.51 mF, which is significantly higher than the benchmark data. This irregularity is an important aspect to consider when assessing the capacitor's applicability for specific circuits and could impact overall performance and stability in frequency-sensitive applications.

Series Resistance

In this section, we will conduct a comprehensive analysis of the series resistance performance of the 0805ZD476MAT2A Capacitor, comparing it against the statistical benchmark data obtained from other components of the same value. This analysis aims to provide engineers with clear insights into the capacitor's series resistance characteristics, assisting them in assessing its suitability for use in their circuits.

Comparing the LCR measurements of the 0805ZD476MAT2A at 1 Volt with the statistical benchmark, we observe key differences in series resistance. At lower test frequencies of 5Hz and 10Hz, the component displays a relatively higher series resistance at 31.31 Ohms and 15.85 Ohms, which is markedly lower than the benchmark average of 44.75 Ohms and 18.59 Ohms, but considerably greater than the respective minimum values of 8.597 Ohms and 4.286 Ohms. It's essential to highlight that higher series resistance at low frequencies can impact circuits where the capacitor is in series with low impedance loads, as it may cause power losses or reduce output voltage levels.

Conversely, as we move into higher test frequencies, the series resistance of the component under test tends to remain consistently lower than the benchmark average values. For instance, at 50Hz, the measured series resistance of the 0805ZD476MAT2A is 3.266 Ohms, marginally higher than the average benchmark value of 3.037 Ohms. This trend can be seen up to a 1MHz test frequency, where the component's series resistance is measured at 42.18m Ohms, substantially below the benchmark average of 280.2m Ohms. This observation highlights the potential superior performance of the component under test in various applications operating at higher frequencies, where low series resistance is desired for improved power efficiency and minimal power loss.

Examining the LCR measurements at 10 Volts, the series resistance values exhibited by the 0805ZD476MAT2A display a similar trend of lower values than the benchmark averages across various test frequencies. For instance, the component exhibits a series resistance of 32.25m Ohms at a test frequency of 20kHz, compared to the benchmark value of 319.4m Ohms. This relative performance sustains throughout all test frequency points, further emphasizing the capacitor's impressive performance in maintaining low series resistance at higher operating frequencies.

In conclusion, the 0805ZD476MAT2A Capacitor demonstrates potentially excellent series resistance performance when compared to the statistical benchmark data, making it a promising candidate for diverse applications where low series resistance at higher operating frequencies is required. This performance characteristic is instrumental in ensuring efficient power transfer and minimal loss within a given circuit, contributing to overall system reliability and longevity.

Dissipation Factor and Quality Factor

In this section, we will delve into the performance attributes of the KYOCERA AVX 0805ZD476MAT2A Capacitor concerning the Dissipation Factor (Df) and Quality Factor (Q) metrics, drawing comparisons with statistical benchmark data. We will provide insights that address the inherent loss characteristics, efficiency, and functional behavior of the capacitor under different operational conditions.

Capacitors with low Df values are highly sought after, as they represent reduced energy losses and improved efficiency performance. On the other hand, high Q values denote superior capacitor functionality, characterized by minimized energy loss in dynamic, frequency-dependent conditions. An evaluation of the 0805ZD476MAT2A LCR measurements at 1 Volt reveals generally low Dissipation Factor values, with a minimum of 0.031 at 500 Hz and 1 kHz and a maximum of 0.044 at 10 Hz and 50 Hz. Benchmark comparisons indicate a reasonably efficient component in terms of energy loss. The Quality Factor, a reflection of the capacitor's overall performance, peaks at 32.56 at 1 kHz and gradually declines with increasing frequency, registering a minimum of 0.07 at 1 MHz. This performance trend illustrates the capacitor's decent adaptability to higher frequency conditions.

When exploring the 0805ZD476MAT2A LCR measurements at 10 Volts, a significant divergence from the 1 Volt test point Df values is detected. Df values exhibit considerable variability, spanning from 0.052 at 500 Hz and 1 kHz to a high of 8.519 at 450 kHz. Such discrepancies in Df values across voltage ratings could suggest potential efficiency concerns in specific application contexts. Conversely, the Quality Factor displays a consistent reduction throughout all tested frequencies, with a maximum of 19.27 at 1 kHz and a nadir of 0.04 at 500 kHz and 550 kHz, implying diminished efficiency in dynamic environments when operating at higher voltage levels.

The KYOCERA AVX 0805ZD476MAT2A Capacitor showcases an acceptable performance profile under lower voltage and frequency operational settings, evidenced by low Df values and high Q values that are indicative of efficient capacitor behavior. However, a drop in performance quality under higher voltage conditions is noticeable, manifested in increased Df values and reduced Q values across the frequency spectrum. These instances might lead to reservations among electronics engineers when considering this component for inclusion in high-voltage, high-frequency applications. Despite this, the 0805ZD476MAT2A Capacitor maintains a respectable performance standard within the Ceramic: X5R category, highlighting its potential in various electronic applications.
