Impedance

This section examines the impedance performance of the Würth Elektronik 74406043047 drum core, wirewound inductor, focusing on its impedance measurements obtained at 1 Volt and comparing them to statistical benchmark data for other components with the same nominal value (4.7μH).

At low test frequencies, such as 5 Hz and 10 Hz, the Würth Elektronik inductor's impedance values appear to align with the benchmark maximum impedance readings (1.774 Ohms and 2.962 Ohms, respectively). As the test frequencies increase, the component's impedance values continue to rise, eventually matching or even exceeding the benchmark maximums. Between 50 kHz and 1 MHz, the measured impedance consistently surpasses the benchmark set maximum impedance.

In the intermediate frequency range of 100 Hz to 1 kHz, the 74406043047 inductor outperforms the benchmark set average impedance, demonstrating its potential for effective operation within specific frequency bands. At a test frequency of 10 kHz, the component's impedance of 3.164 Ohms is both reasonable and persuasive, falling between the benchmark average and maximum values (3.148 Ohms and 3.164 Ohms, respectively).

When subjected to a higher voltage of 10 Volts, the Würth Elektronik inductor continues to perform well at lower test frequencies, such as 5 Hz, 10 Hz, and 50 Hz, exhibiting impedance values of approximately 1.051 Ohms, 1.046 Ohms, and 1.045 Ohms. Yet, as the test frequency reaches 1 MHz, the inductor's impedance surpasses even the highest benchmark value, yielding a reading of 36.61 Ohms as opposed to the benchmark maximum of 32.63 Ohms.

Overall, the Würth Elektronik 74406043047 inductor exhibits a dynamic impedance profile relative to the statistical benchmarks. Engineers must carefully assess the component's impedance performance within the desired frequency range and consider potential high-frequency application scenarios, as the inductor's performance may fluctuate significantly depending on the specific context.

Inductance

Examining the statistical benchmark data, the average inductance at 1V across various frequencies ranges from 4.498μH at 1MHz to 15.29μH at 5Hz. Similarly, at 10 Volts, the average inductance performance of the corresponding benchmark data ranges from 5.796μH at 1MHz to 100.6μH at 5Hz.

At 1V, the 74406043047 demonstrates a significantly higher inductance at low frequencies, starting at 76.44μH at 5Hz, which not only exceeds the maximum benchmark value at this frequency but also makes a substantial difference. This trend continues as the inductance reaches 33.4μH at 10Hz. However, the outperformance steadily decreases as the frequency increases, eventually crossing over to below average at 100Hz with 5.385μH, compared to the average benchmark value of 4.94μH at the same frequency. In the frequency range of 500Hz to 1MHz, the 74406043047's inductance remains relatively consistent with the maximum values of the benchmark data, although slightly higher.

The component demonstrates remarkable outperformance at lower frequencies like 5Hz (100.6μH) and 10Hz (84.62μH). However, there is a noteworthy decrease in inductance at 100Hz (2.16μH) compared to the average benchmark value of 4.93999μH. Beyond that, in the frequency range from 500Hz to 1MHz, the 74406043047 Inductor manages to maintain inductance values between the minimum and maximum benchmark values, ensuring satisfactory performance across a broad spectrum of frequencies.

The Würth Elektronik 74406043047 Inductor exhibits a distinctive inductance performance profile compared to the statistical benchmarks.

Dissipation Factor and Quality Factor

When examining the performance of Würth Elektronik's 74406043047 Inductor, it is crucial to scrutinize its Dissipation Factor (Df) and Quality Factor (Q) at various test frequencies. The Drum Core, Wirewound composition contributes to its overall performance relative to inductors with the same nominal value. These factors indicate energy loss (Df) and the capability of the device to store energy (Q) in reactive power applications, such as filters, oscillators, and transformers.

Taking into account the 1-Volt LCR measurements, the Quality Factor gradually increases as the test frequency advances from 1 kHz (Q = 0.01) up to 1 MHz (Q = 4.38). It suggests that the inductor has better energy storage efficiency at higher frequencies. Similarly, if we assess the 10-Volt LCR measurements, the Quality Factor also escalates rapidly over the test frequency range, starting at 1 kHz (Q = 0.02) and reaching 9.74 at 1 MHz. In both the 1-Volt and 10-Volt scenarios, the progressively increasing Quality Factor supports a favorable performance assessment.

However, to make a comprehensive assessment for the inductor's dissipation factor and quality factor, it is essential to compare the data with benchmark values of similar inductors having a 4.7µH nominal value. Since the Inductor's Df is not explicitly provided for the 74406043047 model, there is a need to procure additional material to obtain a more comprehensive understanding of its performance. Comparing the obtained values with industry standards or manufacturers' specifications will offer better insight into whether the Würth Elektronik 74406043047 Inductor is an optimal choice for the target application or if there are more suitable alternatives available.
