Impedance

When analyzing the impedance performance of the 1206ZD476MAT2A capacitor, it is essential to consider its behavior across various test frequencies and voltage levels. For instance, at 1 volt, this Kyocera AVX capacitor demonstrates a higher impedance across most-test frequencies compared to the average impedance of the statistical benchmark. At 10 Hz, it measures 355.5 Ohms, whereas the benchmark average is 332.8 Ohms. Similarly, at 100 Hz, this capacitor exhibits an impedance of 39.34 Ohms, higher than the benchmark average of 35.87 Ohms. Additionally, at the frequency of 1 kHz, it measures 4.649 Ohms, which is above the benchmark average of 4.046 Ohms.

Continuing with the analysis at a higher voltage, in this case, 10 volts, the 1206ZD476MAT2A capacitor shows higher impedance values as compared to the statistical benchmark data. For instance, at 50 Hz, its impedance value measures 90.66 Ohms, notably above the benchmark average of 69.54 Ohms. At 100 Hz, it reaches 33.88 Ohms, whilst the benchmark data exhibits an average of 35.87 Ohms. Moreover, at the 1 kHz frequency, this particular capacitor's impedance is measured at 3.471 Ohms, favorably lower than the benchmark average of 4.046 Ohms.

Through the entire range of test frequencies and voltage levels, the Kyocera AVX 1206ZD476MAT2A capacitor displays an overall higher impedance compared to the statistical benchmark. At the mentioned frequency points, the capacitor's impedance surpasses both the minimum and average benchmark impedance values. However, it is essential to note that the capacitor presents lower impedance values in some of the higher frequencies (e.g., 100 kHz and 200 kHz).

In the context of electronic circuit design and engineering, the impedance performance of capacitors plays a crucial role in determining their suitability for specific applications. Considering the higher-than-average impedance values exhibited by the Kyocera AVX 1206ZD476MAT2A capacitor, engineers should carefully evaluate its appropriateness for use in their designs. In applications where lower impedance is preferred to minimize voltage drops and maintain a stable power delivery, this particular capacitor might not provide optimal performance compared to alternative components with comparable capacitance values. On the other hand, where higher impedance is beneficial or required, such as in certain types of filters or noise reduction scenarios, the 1206ZD476MAT2A capacitor may be a suitable choice for achieving the desired performance and results.

Capacitance

The 1206ZD476MAT2A capacitor provides a minimum series capacitance of 45.12μF at 5 Hz when tested at 1 Volt, gradually decreasing to 34.09μF at 1 kHz. Comparing this to the typical benchmark for capacitors with similar characteristics, it starts with a slightly lower initial capacitance value, but follows a similar trend in decreasing capacitance as the frequency increases. However, in the 100 kHz to 1 MHz range, it becomes an outlier with a sudden surge in capacitance well above the benchmark, peaking at an impressive 5.836mF at 700 kHz.

When subjected to 10 Volts, the test results reveal some deviations from the typical capacitance trends. For example, the capacitance remains nearly constant between 5 Hz and 50 Hz. Another noticeable difference is the peak capacitance of 49.29μF at 500 Hz, followed by a decline in capacitance as the frequency approaches 1 MHz. Moreover, the measured capacitance for this capacitor between 400 kHz and 500 kHz is substantially higher than the benchmark.

In terms of capacitance characteristics, the 1206ZD476MAT2A capacitor generally aligns with the expected behavior of Ceramic: X5R class capacitors across most frequency bands and showcases excellent performance. Despite adhering to standard expectations in most cases, the performance of this capacitor in particular frequency ranges displays interesting peaks and deviations from the benchmark trends. These specific behavior differences may be valuable for engineers seeking optimal results in applications where these unique characteristics would have a beneficial impact on the overall performance.

Series Resistance

At 1 Volt and 5Hz, the measured Series Resistance for the KYOCERA AVX 1206ZD476MAT2A is 36.95 Ohms, which is notably lower than the benchmark average of 44.75 Ohms. This lower value indicates a better efficiency in the component, potentially reducing energy loss and heat dissipation in the circuit. Additionally, it displays a superior performance at frequencies such as 10 Hz with 18.68 Ohms, compared to the benchmark average of 18.59 Ohms, allowing for more effective operation at different frequency levels.

The performance remains better at higher frequencies like 50Hz, with a Series Resistance of just 3.891 Ohms, compared to the average of 3.037 Ohms, ensuring that the efficiency of the component is maintained even at increased operating frequencies, which is an essential attribute for a variety of applications.

This trend of outperformance continues into higher frequencies, such as 100Hz, 500Hz, and 1kHz, with Series Resistances of 1.887 Ohms, 270.1m Ohms, and 109.7m Ohms, respectively. These values are lower and more efficient than the statistical benchmark averages, which come in at 1.704 Ohms, 567.8m Ohms, and 437.4m Ohms, showcasing the component's ability to function optimally across an extended frequency range.

However, as we look into even higher frequencies, such as 5kHz to 1MHz, the Series Resistances remain lower than or close to the benchmark averages. This demonstrates consistently high-level performance throughout the whole frequency range, providing excellent efficacy when used in various circuits where different frequency levels must be managed.

Furthermore, at 10 Volts LCR Measurements and 5 Hz, the Series Resistance is 74.3 Ohms, notably higher than the 1 Volt measurement. This is expected as the voltage increases, the current in the circuit also increases, leading to a rise in the Series Resistance. Additionally, at higher frequencies such as 500 Hz, the Series Resistance measures 407.3m Ohms, which is again significantly higher when compared to the 1 Volt measurement. It showcases the behavior of the component at different voltage levels and frequency combinations, allowing engineers to make informed decisions about its suitability for specific applications.

Dissipation Factor and Quality Factor

In this section, we will analyze the Dissipation Factor (Df) and Quality Factor (Q) of the KYOCERA AVX 1206ZD476MAT2A Ceramic X5R Capacitor, comparing its performance to the statistical benchmark data provided.

During LCR measurements at 1 volt, we can observe that the capacitor's Df values range from a low of 0.018 at 5kHz to a high of 4.472 at 650kHz. This range deviates slightly from the statistical benchmark, but the low Df observed at 5kHz is a favorable indicator for the capacitor's performance because lower Df values signify less energy loss. The range of Q-values for the same voltage measurement follows a similar trend, with a maximum value of 55.89 at 5kHz and a minimum value of 0.02 at 700kHz. Both values show competence, reflecting the capacitor's capability to store energy efficiently at various frequencies while operating at 1 volt.

Focusing on the LCR measurements at 10 volts, we notice a similar trend in the Df and Q values. The 1206ZD476MAT2A capacitor exhibits the lowest Df of 0.013 at 5kHz and a peak of 0.068 at 5Hz. Comparatively, these values once again indicate that the capacitor performs well within the expected range. The Q values demonstrate a slightly different trend, with a maximum of 74.86 at 5kHz and a dropout in data from 10kHz onwards. The Q value of 74.86 at 5kHz is notably high, emphasizing the capacitor's exemplary energy storage efficiency at this frequency. To clarify, it's crucial to have a high Q value because it represents minimal energy loss in a reactive component over the energy stored per cycle.

The KYOCERA AVX 1206ZD476MAT2A Ceramic X5R Capacitor exhibits adequate performance across the measured Df and Q value ranges, making it a reliable choice for various applications. The capacitor demonstrates low Df values and high Q values, especially at 5kHz frequencies, indicating its excellent energy storage and minimization of energy dissipation. This characteristic makes the 1206ZD476MAT2A a strong contender for engineers who are evaluating capacitors for use in their circuits and require components that provide efficient energy storage with minimal losses.
