Impedance

Throughout a range of test frequencies, the B82144A2472K000 inductor consistently demonstrates higher impedance values than those established by the statistical benchmark average. When examining this component, it becomes clear that its impedance levels vary depending on both the frequency and the input voltage. A comprehensive analysis of these impedance measurements at different frequencies and voltages can provide valuable insights into the performance and potential applications of this inductor.

At a 1 Volt test frequency, the B82144A2472K000 inductor consistently measures higher impedance levels than the statistical benchmark average. For instance, at 50 kHz, the inductor records an impedance of 1.51 ohms, compared to the benchmark average of 1.562 ohms. This trend remains consistent across the entire frequency range, even at higher frequencies such as 550 kHz where the impedance value is 16.48 ohms, while the benchmark average is approximately 15.7 ohms.

When tested at a 10 Volt input, similar performance trends are observed for the B82144A2472K000 inductor. At a 5 kHz test frequency, the inductor registers an impedance of 153.7m ohms, which is considerably lower than the benchmark average of 338.8m ohms. Engineers and designers should carefully evaluate these impedance comparisons to determine the suitability of this inductor for their circuit designs. The tendency of the inductor's impedance values to consistently exceed benchmark averages is a critical factor to consider when assessing its compatibility for specific applications.

It should be noted that impedance values can be greatly influenced by environmental factors such as temperature and humidity. Therefore, designers should also conduct thorough research on these parameters when selecting this inductor for various applications. Overall, a comprehensive understanding of the B82144A2472K000 inductor’s impedance characteristics is essential for making informed decisions regarding its suitability in different types of electronic circuits.

Inductance

In this section, we examine the inductance characteristics of the EPCOS (TDK) Inductor B82144A2472K000 by comparing its observed inductance values with statistical benchmark data. The LCR measurements were carried out at 1V and 10V across a range of test frequencies.

At 1V, the B82144A2472K000 exhibited higher inductance values than the average for the statistical benchmark at low test frequencies (up to 100Hz). Specifically, at 5Hz, its observed inductance reached 10.71μH, which compared to the benchmark's maximum of 76.44μH, is substantially lower, but is still significantly higher than the average (15.29μH) and the minimum (1.023μH). This indicates commendable performance under low-frequency conditions. As the test frequency increased, the component's inductance values displayed a decreasing trend, stabilizing around 4.7-4.8μH from 1kHz up to 1MHz. The inductance remained relatively consistent with the component's nominal value and the average values of the statistical benchmark. This stable behavior in a wide array of frequencies exemplifies reliable performance for numerous applications.

At 10V, the B82144A2472K000 inductor demonstrated considerable deviation from the benchmark at low frequencies. At 5Hz and 10Hz, the component measured substantial inductance values of 69.17μH and 82.51μH, respectively. This high inductance observed at these low frequencies suggests possible non-linear behavior or core saturation in the inductor. However, the inductor's performance appears relatively consistent with the statistical benchmark data for frequencies 50kHz and above. In the 50kHz to 1MHz range, the observed inductance values are within the statistical benchmark's range and exhibit a similar trend to the benchmark data.

Across a wide range of test frequencies, the B82144A2472K000 inductor closely corresponds with the average values of the statistical benchmark in terms of inductance. Nonetheless, potential users should take note of the substantial deviations detected at lower test frequencies, particularly when measured at 10V. For applications operating in the more prevalent frequency range of 1kHz to 1MHz, the B82144A2472K000 provides steady and dependable performance matching the benchmark data of similar wirewound inductors.

Series Resistance

The B82144A2472K000 Inductor demonstrates fluctuating and inconsistent performance across distinct test frequencies when compared to the mean series resistance data derived from benchmarks. For test frequencies ranging from 5 Hz to 20 kHz, the component consistently exhibits a substantially higher series resistance compared to the benchmark averages. This pattern is discernible for both the 1 Volt and 10 Volts measurements, with the B82144A2472K000 Inductor maintaining a noticeable difference of approximately 100m Ohms in series resistance.

At elevated test frequencies above 20 kHz, the B82144A2472K000 Inductor displays an unpredictable pattern in its series resistance measurements, markedly deviating from the benchmark averages at particular frequencies. At 50 kHz and 75 kHz, the Inductor's series resistance ascends to nearly double the mean benchmark values for both 1 Volt and 10 Volts voltage levels. A parallel trend can be observed in the higher frequency band (800 kHz to 1 MHz), wherein the Inductor's series resistance rises to approximately 50-100m Ohms higher than the benchmark averages.

In contrast, the B82144A2472K000 Inductor exhibits a relatively stable performance within the intermediate test frequency ranges from 100 kHz to 700 kHz. Its series resistance values remain within the margin of the minimum and maximum benchmark values. This observation suggests that the Inductor may still be a suitable option for specific applications with particular requirements in this frequency range. However, it is essential for designers to consider the performance deviations at lower and higher frequency regions while selecting components for specific use cases to ensure optimal functionality and efficiency.

Dissipation Factor and Quality Factor

When assessing the Quality Factor (Q) of the B82144A2472K000 inductor under different voltage conditions, important insights can be drawn regarding its efficiency and power losses within circuits. Under a 1V test condition, the Q of the inductor starts at a relatively low level for test frequencies up to 50Hz, but gradually increases beyond 50Hz, ultimately attaining its maximum value of 76.99 at 1MHz. In comparison to benchmark data, the inductor performs remarkably well by maintaining a low dissipation factor (Df) at lower frequencies, while simultaneously achieving a high Q at higher operating frequencies. This indicates that the B82144A2472K000 inductor is highly efficient, producing minimal reactive power losses when utilized in circuits with frequencies spanning from mid to high ranges.

Furthermore, when examining the Quality Factor for the B82144A2472K000 under the more substantial 10V test condition, it is evident that the component continues to remain consistent with the benchmarked data. Here, the Q of the inductor initiates at a minimal value of 5 with a Df of 0.03 at lower test frequencies and eventually peaks at 75.47 as the test frequency reaches up to 850kHz. Overall, the performance of the B82144A2472K000 component remains robust, with its high Q serving as an indicator of exceptional efficiency and minimum power losses within intended applications. Maintaining a low Df and high Q ensures that the inductor is stable and reliable, generating a minimal amount of distortion and noise within the circuits it is employed in. Hence, it is a suitable choice for various electronic devices requiring optimum performance and efficiency.
