Impedance

In this review, we will thoroughly examine impedance performance of the KYOCERA AVX NOJC476M010SWJ Niobium Oxide Capacitor. By comparing its specific impedance values against a statistical benchmark generated from similar components, engineers can determine if this capacitor is suitable for their circuit requirements. Both 1 Volt and 10 Volts test conditions will be covered to provide a comprehensive evaluation of the capacitor's impedance characteristics.

At the 1 Volt test conditions, the NOJC476M010SWJ Capacitor exhibits some variations from the statistical benchmark. Notably, at a low 5Hz testing frequency, the capacitor's measured impedance of 586.6 Ohm is significantly lower than the benchmark's average impedance of 656.9 Ohms. In contrast, at a higher frequency of 10kHz, the capacitor demonstrates an impedance of 448.7m Ohm, which is slightly greater than the benchmark's average of 637.7m Ohms. Despite these deviations, at other test frequencies such as 100kHz (199.5m Ohm vs 319.4m Ohm) and 1MHz (120.9m Ohm vs 286.2m Ohm), the NOJC476M010SWJ Capacitor's impedance remains fairly consistent with the benchmark's average impedance values.

When subjected to the higher 10 Volt testing conditions, the capacitor's impedance performance deviates from the benchmark at certain frequencies. For instance, at lower frequencies like 5Hz and 10Hz, the NOJC476M010SWJ Capacitor's impedance significantly decreases to 125.2 Ohms and 113.7 Ohms, respectively. Besides these variations, the capacitor largely aligns with the benchmark's impedance values at higher frequencies, such as 100kHz (189.7m Ohm) and 300kHz (140.3m Ohm). An interesting observation is at 700kHz, where the capacitor's impedance is measured at 122.4m Ohm, closely matching the 1MHz test result.

Overall, the KYOCERA AVX NOJC476M010SWJ Niobium Oxide Capacitor presents an intriguing option with some deviations from the statistical benchmark for impedance performance. Engineers should thoroughly examine these variations and determine their significance for their specific applications, especially if stability and consistency of impedance values in particular conditions are critical factors for optimal circuit performance.

Capacitance

In evaluating the capacitance performance of the KYOCERA AVX NOJC476M010SWJ Capacitor, measurements were conducted across a wide range of test frequencies, specifically from 5 Hz to 1 MHz. Two voltage ratings were employed in the tests, 1-Volt and 10-Volt, to obtain a comprehensive understanding of the capacitor's behavior under differing conditions.

It is notable that at the lower end of the test frequency spectrum, below 20 kHz, the capacitor demonstrates high capacitance values that surpass the average benchmark. This attribute becomes particularly marked under 1-Volt test conditions. For instance, at 5 Hz and 1-Volt operation, the capacitor exhibits a capacitance value of 56.52μF, significantly higher than the average benchmark value of 49.2μF. Similarly, at 10 kHz and 1-Volt operation, the capacitor's capacitance reaches 44.14μF, well beyond the average benchmark value of 37.07μF.

However, as the test frequency surpasses 20 kHz at 1-Volt operation, the NOJC476M010SWJ's performance diminishes. Specifically, the capacitance values measured are not only below the average benchmarks but also lower than the minimum benchmarks established for the capacitor. For example, at 50 kHz and 1-Volt operation, the measured capacitance of 26.31μF falls short of the average benchmark value of 31.64μF and lags behind the minimum benchmark value of 12.85μF.

This observed trend remains consistent when considering the measurements obtained using the 10-Volt rating. Although the capacitor outperforms the statistical benchmarks in the test frequency range between 5 kHz and 20 kHz, its performance declines beyond the 20 kHz threshold. To illustrate, at 50 kHz and 10-Volt operation, the capacitor's capacitance value is 25.6μF, once again trailing the average benchmark of 31.64μF.

Overall, the KYOCERA AVX NOJC476M010SWJ Capacitor displays impressive capacitance values at lower test frequencies (<20kHz), outperforming the respective statistical benchmarks. However, its performance struggles at higher test frequencies (>20kHz), as its measured capacitance values tend to be lower than the relevant benchmark data. Accordingly, the capacitor's appropriateness within a specific application will depend on key factors such as frequency requirements and operating conditions.

Series Resistance

In this section, we will analyze the performance of the KYOCERA AVX NOJC476M010SWJ Niobium Oxide Capacitor's Series Resistance in comparison with the provided benchmark data. Series resistance, also known as Equivalent Series Resistance (ESR), is an essential parameter to look at in capacitors, as it directly influences the power dissipation, temperature rise, and efficiency of a capacitor in a circuit.

When examining the LCR measurements at 1 Volt, the capacitor's series resistance ranges from a maximum of 140.5 Ohms at 5 Hz to a minimum of 120.7m Ohms at 1 MHz, generally displaying better performance than the average benchmark data. Notable results include 40.92 Ohms at 10 Hz, which is significantly lower than the benchmark's 18.59 Ohms, and 798m Ohms at 100 Hz, an improvement over the benchmark's 1.704 Ohms. However, at 500 Hz and 1 kHz, the NOJC476M010SWJ displays a higher series resistance (368.1m Ohms and 319m Ohms), respectively, compared to the benchmark average (567.8m Ohms and 437.4m Ohms, respectively). This difference in ESR values might be due to different capacitance values, temperature, or component quality.

When analyzing the LCR measurements at 10 Volts, we can observe similar trends in the capacitor's performance. At low frequencies (5 Hz and 10 Hz), the NOJC476M010SWJ outperforms the benchmark with series resistance values of 119.6 Ohms and 96.45 Ohms, respectively. As the frequency increases, the capacitor maintains a better performance, up to 20 kHz, where its 256.1m Ohms series resistance is slightly below the benchmark's 319.4m Ohms. Beyond 50 kHz, the capacitor's series resistance values become consistent with the average benchmark data, ranging from 180.7m Ohms at 75 kHz to 137.6m Ohms at 250 kHz. This competitive behavior with the benchmark indicates that the NOJC476M010SWJ capacitor maintains a stable and consistent performance across a wide range of frequencies.

Overall, the KYOCERA AVX NOJC476M010SWJ Niobium Oxide Capacitor exhibits a commendable series resistance performance, generally outperforming the provided benchmark data. By understanding the ESR behavior of this capacitor, engineers can make informed decisions when designing electronic circuits and selecting capacitors for optimum system performance.

Dissipation Factor and Quality Factor

When assessing the applicability of a capacitor for electronics engineering projects, engineers need to consider the performance of crucial parameters, Dissipation Factor (Df) and Quality Factor (Q). In the case of KYOCERA AVX's NOJC476M010SWJ, a 47μ Niobium Oxide capacitor, it is essential to contrast its performance against suitable statistical benchmarks across a range of test frequencies and voltages in order to make informed decisions on its effectiveness in specific applications.

At low test frequencies (1 V), the NOJC476M010SWJ demonstrates a Dissipation Factor (Df) ranging from a high of 0.267 at 5 Hz to a low of 0.023 at 50 Hz. As the test frequency increases, the Df gradually increases. This performance suggests that the low-frequency Df of the NOJC476M010SWJ could be optimized for better performance by potentially minimizing its internal resistive components or selecting a capacitor with a lower Df in this range.

At higher test voltages (10 V), the capacitor's Df exhibits a similar trend as with 1 V, starting relatively high at 3.055 at 5 Hz and reaching a minimum of 0.421 at 50 Hz. However, the Df values are generally higher at the 10 V test voltage than at 1 V, which means engineers may need to evaluate their circuits for potential noise and power loss trade-offs more carefully when subjecting the NOJC476M010SWJ to higher voltages. Understanding the implications of these varying Df values ensures proper function of circuits and avoids potential issues related to loss and performance.

Regarding Quality Factor (Q), high values are desired as they indicate efficient energy storage and release within a capacitor. The NOJC476M010SWJ capacitor exhibits its best Q of 44.16 at 50 Hz with a 1 V test voltage. However, above 20 kHz, the Q values drastically decrease in both 1 V and 10 V test scenarios. This trend is noticeable below the benchmark thresholds when compared, indicating that applications requiring high Q values at higher frequencies may not be suitable for this capacitor. Therefore, engineers must find alternative capacitors that provide a required Q value to maintain circuit efficiency across the desired frequency range.

However, it should be noted that at certain test frequencies, the NOJC476M010SWJ falls within the benchmark range, notably on qualities such as higher frequency impedance and capacitance values. Moreover, a slight improvement is observed in the capacitor's performance when tested at 10 Volts, as evidenced by a significant increase in capacitance values at lower frequencies.

Therefore, while the NOJC476M010SWJ may not outshine its contemporaries in every avenue, it remains a viable choice for specific applications where higher frequency impedance and increased capacitance values are sought.
