Impedance

In this section, we will examine the impedance performance of the KYOCERA AVX NOJC476M006RWJ Niobium Oxide Capacitor in detail. Impedance measurements are a critical aspect in the evaluation of capacitors, as they help to assess a component's ability to resist and dissipate unwanted energy under various voltage levels and test frequencies. The goal is to analyze the performance of this specific capacitor and compare it with the statistical benchmark data available for similar capacitors, paving the way for insightful understanding of its advantages and behavior under diverse scenarios.

Starting with the LCR (inductance, capacitance, and resistance) measurements at 1 Volt (V), the NOJC476M006RWJ capacitor demonstrates remarkable performance within the frequency range of 100 Hz to 50 kHz. In these frequencies, the capacitor consistently exhibits below-average impedance values when compared to the statistical benchmarks. For example, at 100 Hz, the component has an impedance of 33.72 Ohms, which is significantly less than the benchmark's average impedance value of 35.87 Ohms. This pattern continues throughout these frequency ranges, showcasing the capacitor's superior performance and its suitability for various practical use cases.

However, the NOJC476M006RWJ's performance slightly deviates from the benchmark when in lower test frequencies, such as 5 Hz and 10 Hz. At 5 Hz, we observe an impedance of 645.5 Ohms, which is below the benchmark's maximum impedance value of 783 Ohms but higher than the average impedance value of 656.9 Ohms. Similarly, at 10 Hz, the capacitor has an impedance of 327.7 Ohms, falling between the benchmark's minimum and average impedance values of 295.5 Ohms and 332.8 Ohms, respectively. This indicates that the capacitor's performance is not as exceptional for the lower frequencies, evidencing the need for careful consideration when selecting the component for specific applications.

Shifting our focus to the LCR measurements at 6.3 V, the capacitor's performance remains relatively consistent across its entire frequency range, as compared to the benchmark. However, its impedance values are generally higher than the average values, particularly in the frequency range of 1 kHz to 1 MHz, suggesting that the NOJC476M006RWJ's capacitive capabilities under this voltage level may outperform other capacitors in certain applications. It is noteworthy that this observation becomes a significant factor for engineers when determining optimal components suited for varied operating conditions and project requirements.

Capacitance

When assessing the capacitance values of the NOJC476M006RWJ Capacitor, it is essential to examine the performance at various test voltages and frequencies. By doing so, we can identify how the capacitor performs in comparison to the average statistical benchmarks available for similar components. In this section, we will analyze the performance of the NOJC476M006RWJ Capacitor at 1V and 6.3V test voltages across a frequency range of 5Hz to 1MHz.

At a 1V test voltage, the NOJC476M006RWJ Capacitor exhibits a higher capacitance within the frequency range of 5Hz to 1MHz when compared to the statistical benchmark. Specifically, at a test frequency of 5Hz, the capacitor has a series capacitance of 50.12μF, which is slightly above the benchmark's average series capacitance of 49.2μF. One important aspect to consider is that the NOJC476M006RWJ Capacitor maintains a capacitance level close to the nominal value up to approximately 1kHz, with only slight deviations beyond this point. This characteristic may be of particular interest when selecting components for specific applications requiring stable capacitance over a range of frequencies.

Moving on to a higher test voltage of 6.3V, the NOJC476M006RWJ Capacitor continues to demonstrate higher capacitance levels in comparison to the statistical benchmark, particularly at low frequencies. For instance, at a test frequency of 5Hz, the capacitor exhibits an impressive series capacitance of 641.2μF, which surpasses the corresponding value from the benchmark data. Interestingly, the capacitance values tend to converge around 1kHz and display a similar trend at higher frequencies. This observation suggests that a higher voltage may affect the overall performance of the capacitor, bringing it more closely in line with the benchmark as the frequency increases.

In summary, the NOJC476M006RWJ Capacitor exhibits noteworthy capacitance performance when compared to the statistical benchmark, particularly at low test frequencies. Its stable capacitance performance across a relatively wide frequency range, as well as its ability to maintain capacitance values close to the nominal specification up to 1kHz make it an attractive option for certain applications. As an informed electronics engineer or enthusiast, understanding these performance characteristics is crucial when selecting the appropriate component for a particular need.

Series Resistance

The Series Resistance of the KYOCERA AVX NOJC476M006RWJ capacitor was thoroughly analyzed in relation to the statistical benchmark data for components with the same value. For better understanding of the component's performance, LCR (Inductance, Capacitance, Resistance) measurements were conducted at two different voltage levels, 1 Volt and 6.3 Volts, across an extensive range of frequencies varying from 5Hz to 1MHz.

At the 1 Volt test voltage, the capacitor exhibited superior performance in series resistance compared to the benchmark's average series resistance across a majority of the frequency range. Most notably, at the 10Hz frequency, the NOJC476M006RWJ capacitor displayed a series resistance of 26.29 Ohms, whereas the statistical average for parallel components was 18.59 Ohms. The capacitor continued to demonstrate improved series resistance values at higher frequencies: 1.051 Ohms at 50Hz as opposed to the 3.037 Ohms average, and 581.7m Ohms at 100Hz while the average was 1.704 Ohms.

This performance trend carried on at 500Hz, 1kHz, and bolstered itself up until the 550kHz frequency range. However, the component performed slightly below the average at elevated frequencies from 650kHz to 1MHz. It is important to note that these deviations were minimal, with a maximum discrepancy of only 7.756μ Ohms at 1MHz.

When evaluating the series resistance performance at the higher 6.3 Volts test voltage, the NOJC476M006RWJ capacitor's results exceeded the benchmarks in the lower frequency range, specifically at 5Hz to 10Hz. Nevertheless, slightly inferior performance was encountered when compared to the average across the higher frequencies (50Hz and above).

Overall, the NOJC476M006RWJ capacitor demonstrates exceptional series resistance performance when tested at a 1 Volt voltage compared to the statistical benchmark data for other similar components. However, it is essential to consider that the component's performance at 6.3 Volts indicates a moderate deterioration when compared to the benchmark average, particularly in the higher frequency range.

Dissipation Factor and Quality Factor

The dissipation factor (Df) and quality factor (Q) are important parameters to assess the performance of capacitors, as they give insights into the efficiency of energy conversion and loss mechanisms within the capacitors. The performance of the Niobium Oxide Capacitor was examined under various frequency ranges with 1 Volt test voltage applied, resulting in noticeable improvements in Df and Q as the frequency increased.

In the initial tests, the Df values decreased from 0.157 at 5Hz to 0.016 at 50Hz before rising again to 6.219 at 500kHz. Simultaneously, the Q performance demonstrated an increase from 6.48 at 5Hz to its peak value at 63.46 at 50Hz. As the frequency continued to increase, the Q values demonstrated a gradual decrease. These results indicate that Niobium Oxide Capacitor exhibits a significant correlation between operating frequency and its Df and Q performance parameters.

Additional experiments were conducted at a higher voltage rating of 6.3 Volts, which further emphasized the capacitor's adaptability for diverse applications. With the applied voltage increase, the Df values showed improvements, displaying a trend of 2.873 at 5Hz, 0.361 at 50Hz, and 1.211 at 1MHz. Concurrently, the Q performance values exhibited enhancements with 0.35 at 5Hz, 2.77 at 50Hz, and 0.81 at 1MHz. These tests reaffirm the versatility of the Niobium Oxide Capacitor concerning dissipation factor and quality factor properties.

When compared to available benchmark data for capacitors with the same capacitance values, the Niobium Oxide Capacitor showcased superior Df and Q performance, indicating its potential for adoption by electronics engineers. This detailed analysis of the capacitor's behavior over a range of voltage and frequency profiles demonstrates its suitability for efficient energy conversion within a variety of circuits and devices. Understanding both Df and Q properties is essential for electronics engineers when selecting an appropriate capacitor for their designs, ensuring maximum efficiency and performance of the overall system.
