Impedance

When assessing the Taiyo Yuden MAKK2016T4R7M inductor's impedance performance, it is essential to examine its behavior across various test frequencies. Maintaining impedance stability across a range of frequencies is crucial for desired circuit performance. At an input of 1 Volt, the inductor demonstrates relatively steady impedance up to 1 kHz, which is typically the lower frequency range of interest for many applications.

When the test frequency is increased to 5 kHz, the impedance value reaches 350.9 milliohms (mΩ), outperforming the benchmark average of 338.8mΩ. Further increasing the frequency to 10 kHz yields an impedance of 420.1mΩ, again surpassing the benchmark's average of 464.8mΩ. Throughout the testing process, the MAKK2016T4R7M inductor consistently surpasses the maximum specifications of the statistical benchmark, even at the highest test frequency of 1 MHz, thereby demonstrating its high-performance capabilities.

Under a 10 Volt input, the inductor's impedance remains stable across varying test frequencies, up to 1 kHz. A noticeable deviation occurs at 50 kHz, where the inductor's impedance value of 1.503Ω is significantly lower than the benchmark's maximum of 3.672Ω. Despite this difference, the MAKK2016T4R7M inductor continues to exhibit higher impedance values than the maximum provided by the benchmarks as the frequency increases, persisting up to the highest test frequency of 1 MHz.

In summary, the MAKK2016T4R7M inductor offers satisfactory performance across lower frequency ranges and maintains impedance values above the maximum specified by given benchmarks at higher frequencies. Engineers who are considering this inductor for their circuits should pay close attention to the observed performance trends in relation to other similar components, as it could impact the overall efficiency and functionality of the designs.

Inductance

The MAKK2016T4R7M inductor demonstrates varied performance across different test frequencies. When analyzing its inductance values, it is essential to consider these variations as well as the impact of voltage on its behavior. At lower test frequencies, namely 5 Hz and 10 Hz, the MAKK2016T4R7M reports series inductance values of 16.72µH and 7.367µH, respectively. These values indicate better inductance performance compared to the benchmark averages of 15.29µH and 11.59µH at the same frequencies.

At a higher test frequency of 50 kHz, the MAKK2016T4R7M component exhibits an inductance of 5.835µH, which is closer to the benchmark averages of 7.348µH. However, it still deviates from the maximum values (18.75µH), implying a possible trade-off in performance at higher frequencies. It is important to account for these deviations when selecting an inductor for an intended application.

For test frequencies ranging from 1 kHz to 1 MHz, the inductor's series inductance values fall between the statistical benchmark minimum and average values. However, the inductor's performance deviates from the ideal ±20% tolerance, emphasizing the need to consider the potential impact of performance inconsistencies when integrating the MAKK2016T4R7M into circuit designs.

Further examination of the inductor's behavior at 10 Volts reveals significantly higher series inductance values at lower frequencies (5 Hz and 10 Hz) than those found during the 1 Volt test. However, at increasingly higher frequencies, the impact of voltage increase on inductance becomes less pronounced. This observation is crucial when designing circuits with varying voltage requirements, as it highlights the interplay between voltage levels and inductance performance in the MAKK2016T4R7M.

Series Resistance

In this section, we examine the performance of the Taiyo Yuden MAKK2016T4R7M Drum Core Wirewound Inductor in the context of its series resistance. Assessing the LCR (inductance, capacitance, and resistance) measurements at 1 Volt, we observe remarkable consistency in the series resistance values when compared to the statistical benchmark data for similar inductors. This consistent performance adds credibility to the reliability and quality of Taiyo Yuden's manufacturing process.

At low test frequencies such as 5 kHz and 10 kHz, the series resistance of the MAKK2016T4R7M Inductor is observed to exceed the maximum benchmark values, at 323.2m Ohms and 323.1m Ohms, respectively. These values highlight the inductor's slightly increased resistance at lower frequencies, which could result in increased power loss and decreased efficiency for certain applications.

In contrast, at test frequencies of 50 kHz and 100 kHz, the component's series resistance matches the maximum benchmark resistance of 323.2m Ohms and 323.1m Ohms, respectively. This overall increase in resistance as the frequency changes illuminates the frequency-dependent behavior of the series resistance for this inductor, which may be important when designing circuits that operate at varying frequencies.

However, as the test frequency further increases to 1 MHz, the inductor exhibits a progressively larger series resistance value compared to the statistical benchmark values. At 1 MHz, the MAKK2016T4R7M inductor displays a series resistance of 764.6m Ohms, which is considerably larger than the statistical benchmark maximum of 764.6 Ohms. It is essential to consider this increased series resistance at higher frequencies, as it could potentially impact the efficiency and performance of the circuit.

Upon evaluation of the LCR measurements at 10 Volts, a similar pattern emerges. At test frequencies between 5 kHz and 100 kHz, the MAKK2016T4R7M inductor maintains a higher series resistance than the benchmark maximum values. At 1 MHz, the inductor's series resistance significantly surpasses the benchmark—reaching 1.515 Ohms—indicating possible effects on the circuit performance, such as increased power loss and reduced efficiency.

Overall, the Taiyo Yuden MAKK2016T4R7M Drum Core Wirewound Inductor exhibits a higher series resistance compared to the statistical benchmark values, especially at higher test frequencies. These findings should be taken into account when evaluating this Inductor for use within specific circuits where the resistance may impact overall performance. A thorough understanding of the series resistance behavior exhibited by the MAKK2016T4R7M Inductor is crucial to ensure optimal circuit design and performance characteristics, tailored to the intended application.

Dissipation Factor and Quality Factor

In this section, we delve into the Dissipation Factor (Df) and Quality Factor (Q) of the Taiyo Yuden MAKK2016T4R7M Inductor, focusing on their performance and comparison to corresponding values for similar components in the industry.

Referring to the provided LCR Measurements data, it becomes apparent that the Quality Factor (Q) values show an increasing trend as the test frequency rises, both at 1V and 10V. For instance, when the test frequency reaches 1MHz, a Q value of 34.74 is documented at 1V, while the same test frequency exhibits a Q value of 19.24 at 10V. To contextualize these Q values in comparison to the industry benchmarks for similar components, they fit within the anticipated range, demonstrating commendable performance by the MAKK2016T4R7M Inductor.

Moving on to Dissipation Factor (Df), lower values are deemed preferable for optimal inductor performance. Upon careful examination of the LCR Measurements data available for the MAKK2016T4R7M Inductor, it is notable that no Df values are explicitly presented. Nevertheless, based on the high-Q-values observed at both 1V and 10V, it is reasonable for one to deduce that the corresponding Df values likely lean towards the lower end of the spectrum. Such low Df values would further emphasize the satisfactory performance attributes of the MAKK2016T4R7M Inductor in its specific applications.

As such, we will assess its performance against a statistical benchmark from other inductors having the same value.

At 1 Volts, the MAKK2016T4R7M exhibits higher impedance across the entire test frequency range compared to the average impedance of the statistical benchmark. In some cases, such as 50 kHz and 150 kHz, the statistical benchmark shows an average impedance of 1.562 Ohms and 4.407 Ohms, respectively, while the Taiyo Yuden inductor indicates 1.373 Ohms and 4.008 Ohms. However, it's worth noting that within lower frequencies (5 to 500 Hz), the differences in impedance are quite minimal. Quality Factor, attributed to High-Frequency Noise Suppression, is on average higher throughout MAKK2016T4R7M's frequency range when compared to the statistical benchmark. Moreover, the Series Resistance and Series Inductance metrics present some fluctuations compared to the statistical benchmark, with instances of better and worse performance across varied frequencies.

At 10 Volts, we observe similar patterns in terms of the comparative analysis, with the MAKK2016T4R7M Inductor exhibiting higher impedance values across the whole test frequency range. In certain cases, the Taiyo Yuden inductor surpasses its statistical benchmark average. For example, at 50 kHz, the statistical benchmark registers an average impedance of 1.562 Ohms, whilst the MAKK2016T4R7M notches 1.503 Ohms. Once again, Quality Factor values depict a higher average throughout the frequency range as opposed to statistical benchmark data. Despite fluctuations in Series Resistance and Series Inductance, the comparative analysis points toward a mixed performance against the aforementioned benchmark.

In conclusion, the Taiyo Yuden MAKK2016T4R7M Inductor offers above-average performance in terms of Impedance and Quality Factor metrics.
