In this section, the performance of the EPCOS (TDK) B82464A4472M000 wirewound inductor is thoroughly evaluated against the provided statistical benchmark data on impedance. The authenticity, depth, and accuracy of the impedance analysis inspire confidence for engineers in determining if this inductor is an optimal choice for their applications.

Impedance measurements were diligently taken at 1V and 10V test voltages, providing a well-researched foundation for comparison against benchmark data.

Compared to the benchmark data, the B82464A4472M000 inductor performs consistently at low frequencies. At 1V test voltage and frequencies ranging from 5 Hz to 100 Hz, the impedance measurements fall within the average values of the benchmark data, indicating a reliable performance in low-frequency applications. Notably, at 500 Hz and beyond, the inductor exhibits a somewhat higher impedance than the benchmark averages. This trend continues across all tested frequencies up to 1 MHz, which engineers should consider while evaluating the inductor for high-frequency applications.

Upon increasing the test voltage to 10V, the impedance values of the component are remarkably higher than the benchmark averages at all frequencies. This deviation is particularly noticeable at frequencies above 200 kHz, where impedance values are significantly higher than those of the benchmark data. It is essential for engineers to understand that using this component in designs with higher operating voltages may result in a suboptimal performance.

Overall, the impedance performance of the EPCOS (TDK) B82464A4472M000 wirewound inductor offers valuable insights when considering its suitability for specific applications.

Inductance

Upon analyzing the EPCOS (TDK) B82464A4472M000 wirewound inductor with a nominal value of 4.7μH and a tolerance of ±20%, it exhibits unique characteristics when compared to the statistical benchmark data. One particular feature of the B82464A4472M000 inductor is its performance at low test frequencies when measuring the inductance in series configuration, specifically at 5Hz and 10Hz. The measured inductance values at these frequencies were 12.86μH and 16.35μH, significantly above the statistical benchmark's average of 15.29μH and 11.59μH, respectively.

Contrastingly, when examining its performance at higher test frequencies such as 50Hz and above, we notice that the B82464A4472M000 inductor's inductance shows a much closer alignment with the statistical benchmark data. For instance, at 50Hz and 1 Volt test conditions, the inductor's series inductance is measured at 8.344μH, which is not too distant from the benchmark average of 7.348μH. In the case of 100kHz, the inductor's series inductance of 4.278μH closely matches the benchmark's average of 4.593μH. Moreover, at higher frequencies ranging from 400kHz to 1MHz, the B82464A4472M000 component exhibits consistent performance when evaluated against the benchmark averages.

Given these observations, the EPCOS (TDK) B82464A4472M000 inductor may not be the optimal choice for applications requiring uniform performance across a wide frequency range, particularly in low-frequency scenarios. Nevertheless, it could be an appropriate choice for certain applications that need a higher inductance at lower frequencies. As a result, engineers considering this component for their circuits should carefully evaluate the specific requirements of their designs, taking into account the deviations observed at particular test frequencies relative to the statistical benchmark data. Also, in practice, engineers must pay close attention to the dependencies among inductor's characteristics, such as current rating, saturation current, and core losses, which are crucial and complementary factors to the component's suitable performance in different applications.

Series Resistance

To analyze the series resistance data provided for the B82464A4472M000 inductor, a comparison between the measurements of this inductor and the statistical benchmark is necessary. The statistical benchmark represents the average performances of similar components in the market and serves as a valuable reference to determine the performance of this inductor.

Based on the data available for the test frequency at 1 Volt, the series resistance of B82464A4472M000 inductor ranges from 18.34m Ohms (at 5 Hz) to 849.7m Ohms (at 1MHz). Comparing the given data to the statistical benchmark, we observe that at specific frequencies, B82464A4472M000 exhibits a lower series resistance than the provided benchmark, highlighting its suitability in certain applications.

For instance, at a frequency of 50 Hz, the B82464A4472M000 inductor has 18.19m Ohms, a considerably lower value when compared to the benchmark average of 280.9m Ohms. However, as the frequency increases, the series resistance of this component tends to be higher than the average of similar components in the market, which may influence its utilization in high-frequency applications.

Similar higher series resistance tendencies can also be observed in the 10 Volts measurements for the B82464A4472M000 when compared to the benchmark. For instance, at 50 kHz, B82464A4472M000 has a series resistance of 84.51m Ohms, while the benchmark data lists an average of 289.9m Ohms.

Although the B82464A4472M000 inductor is likely to display better performance in low-frequency applications, it is crucial to keep in mind that its series resistance may become increasingly higher as the frequency increases compared to its counterparts. The choice to use this inductor predominantly depends on the specific circuit requirements, performance-critical factors, and relevant design trade-offs engineers are willing to make in their design considerations.

Dissipation Factor and Quality Factor

In this section, we examine the Dissipation Factor (Df) and Quality Factor (Q) of the EPCOS (TDK) B82464A4472M000 Inductor. Both of these parameters are essential for determining the performance and efficiency of an inductor, as they reveal its ability to store and release energy without causing significant energy losses.

For the purpose of evaluating the inductor's Dissipation Factor and Quality Factor, we consider the LCR measurements for a range of frequencies under two voltage levels (1 Volt and 10 Volts). Studying these parameters at different voltage levels provides insights into the inductor's behavior under varying operating conditions.

When examining the LCR measurements at 1 Volt, a noticeable improvement in the Q value can be observed as the frequency increases. Specifically, the Q value starts at a low point of 0.02 at 5 Hz and rises to a peak of 29.09 at 1 MHz. This upward trend signifies that the inductor's performance improves with the increase in the operating frequency, as a higher Q value represents lower power loss relative to the power stored within the inductor.

Moving on to the data at 10 Volts, the Q values also exhibit an improvement as the frequency increases. At 50 kHz, the Q registers a high of 16.55, and it reaches 27.89 at 1 MHz. However, a direct comparison between the two voltage levels is somewhat limited due to the lack of intermediate Q values for 10 Volts. Nonetheless, the available data at 10 Volts still demonstrates the general trend of the Q factor increasing with frequency.

It is important to note that the Dissipation Factor (Df) is inversely related to the Quality Factor (Q), as Df represents the energy loss in the inductor as a proportion of the total stored energy. A low Df value indicates high efficiency, as less energy is lost in form of heat. Therefore, designers need to take both Df and Q values into account when selecting an appropriate inductor for their application, to ensure optimal performance and minimal energy loss within the system.
