Impedance

In this section, the review provides an in-depth analysis of the impedance performance of the Yageo FKN200JR-73-0R1 Wirewound Resistor. To accomplish this analysis, LCR measurements at 1 and 10 Volts are compared with the statistical benchmark data for components with similar values. Impedance, which refers to the opposition a circuit element presents to the flow of alternating current (AC) at a given frequency, is a critical parameter that determines the suitability of a component for specific applications.

When comparing the FKN200JR-73-0R1 data at 1 Volt to the benchmark data, it is observed that the Resistor has consistently higher impedances across the entire frequency range. For instance, at a low frequency of 5Hz, it exhibits an impedance of 98.36mΩ, compared to the average benchmark value of 91.73mΩ. As the frequency increases, the difference in impedances continues to expand. This trend is maintained at higher frequencies, such as 1MHz, with the Resistor registering an impedance of 194.5mΩ, significantly higher than the benchmark average of 108.3mΩ.

Upon examining the 10 Volt LCR measurements, it is observed that the impedances are initially lower at lower frequencies compared to the 1 Volt measurements. For example, at 5Hz and 10Hz, the impedances measure 53.34mΩ and 51.07mΩ, respectively. The impedance values begin to converge with the 1 Volt measurements as the frequency increases. However, data becomes incomplete as we progress to higher frequencies from 600kHz onwards.

From the detailed analysis, it can be inferred that the Yageo FKN200JR-73-0R1 consistently demonstrates higher impedances across the examined frequency range compared to the statistical benchmark. Engineers should take these findings into account while evaluating the Resistor's performance for use in their products, particularly in applications where impedance values are critical for the overall functionality, efficiency, and signal integrity of the electronic system. A higher impedance could lead to reduced performance, increased power dissipation, or parasitic effects, depending upon the specific requirements of the application.

Resistance

Our in-depth technical review on the resistance of Yageo's FKN200JR-73-0R1 wirewound resistor provides valuable insights into its stability under varying conditions. Stability is a key factor for engineers when selecting components, as fluctuations in resistance can severely impact the performance of their circuits.

LCR measurements at 1 Volt demonstrate that resistance values do not deviate significantly within the lower test frequencies - deviations remain within the tolerance range. However, as the test frequency increases, a steady increase in deviation is observed. This reaches its peak at 1MHz, with a series resistance of 110mΩ, a deviation that extends beyond the specified tolerance range.

When subjecting the FKN200JR-73-0R1 resistor to LCR measurements at 10 Volts, the series resistance exhibits noticeable fluctuations. Within the lower test frequency range (5Hz-20kHz), resistance values exhibit a substantial reduction compared to the measurements obtained at the 1 Volt test. At 20kHz, the resistor records its lowest value of 40.68mΩ. A notable shift occurs within the range of 50kHz-300kHz, with resistance values increasing and surpassing the nominal value of 100mΩ. As the test frequency exceeds 300kHz, the resistance values continue to climb, exhibiting ever-growing deviations relative to the nominal value.

This comprehensive analysis reveals that Yageo's FKN200JR-73-0R1 wirewound resistor experiences fluctuations in resistance that become more pronounced as test frequencies and voltages increase. While the resistor's performance adheres to the specified tolerance limits under lower frequency ranges, it displays deviations that exceed the outlined benchmark data in higher frequency scenarios. Consequently, engineers should carefully assess the suitability of this resistor for their circuits, considering its resistance behavior under varying conditions and potential limitations on performance when operating in higher frequency domains.

Inductance

In this section, we thoroughly analyze the inductance performance of the Yageo FKN200JR-73-0R1 Resistor. The inductance data provided for this resistor at 1V and 10V test frequencies will be carefully compared to a statistical benchmark formed by an assortment of resistors with the same nominal value.

At a 1V test frequency, the FKN200JR-73-0R1 Resistor displays a maximum series inductance of 41.9μH at 5 Hz, which is below the statistical benchmark maximum value of 50.8μH. This indicates that the resistor under consideration offers better inductance performance in the lower frequency range. On the other hand, at higher frequencies, such as 100 kHz, the FKN200JR-73-0R1 has a series inductance of 29.58nH. This is lower than the statistical benchmark maximum of 35.92nH, demonstrating satisfactory performance compared to other resistors operating at similar frequencies.

When increasing the test voltage to 10V, the FKN200JR-73-0R1 Resistor demonstrates improved inductance performance at lower frequencies. For instance, at 5 Hz, the resistor has an impressive 107.5μH of series inductance, which considerably outperforms its 1V benchmark. However, as the frequency increases, the inductance reduces and reaches around 19.25nH of series inductance compared to the statistical benchmark of 36.23nH at 50 kHz. This observation signifies that the component's inductive response diminishes at higher frequencies.

It is crucial to mention that certain inductance values for the 10V test frequency are not provided for intermediate frequencies ranging from 500 Hz to 10 kHz, as well as certain higher frequencies, such as 600 kHz, 650 kHz, 700 kHz, and others. This lack of data limits a comprehensive comparison of the component's performance at these specific frequencies. Nevertheless, the available information suggests that the Yageo FKN200JR-73-0R1 Resistor exhibits satisfactory inductance performance when compared to the statistical benchmark data, making it an ideal choice for various applications that require competent inductance behavior.

Comparative Analysis

In this comparative analysis, we will assess the performance of Yageo's FKN200JR-73-0R1 Resistor against the statistical benchmark of similar valued components. As a wirewound type with a nominal value of 100m Ohms and a tolerance of ±5%, this resistor is expected to perform differently depending on the data gathered from the benchmark and the measured LCR values at different frequencies and voltages.

Starting with the LCR measurements at 1 Volts, the FKN200JR-73-0R1 resistor shows a higher impedance across multiple test frequencies when compared to the average impedance values from the benchmark data. At 5 Hz, for instance, the impedance (98.36m Ohms) is significantly higher compared to the benchmark average (91.73m Ohms). A similar trend is observed across the entire frequency range, with the measured impedance remaining higher than the average value from the benchmark.

However, at 10 Volts, the impedance values of the FKN200JR-73-0R1 resistor are comparatively lower than that of the measurements at 1 Volt. The trend of higher impedance values holds valid for the results at 10 Volts as well, with values consistently higher than the benchmark average.

When examining the quality factor and series resistance values, noticeable deviations are observed in comparison to the benchmark data. For example, at 5 kHz test frequency, the quality factor comes out to be 0.01, which is in line with the benchmark average. However, the series resistance (98.43m Ohms) remains higher than the benchmark average (91.93m Ohms).

Considering the series inductance values, significant variations have been observed compared to the benchmark band. For instance, at 5 Hz, the inductance is 4.042μ Henries, which is greater than the benchmark maximum value of 5.906μ Henries, while at 10kHz, the measured inductance (36.57n Henries) falls within the benchmark's minimum, average, and maximum values (1.303n, 7.925n, and 39.75n).

After analyzing the given data, it is evident that the Yageo FKN200JR-73-0R1 Resistor diverges from the statistical benchmark in terms of impedance, series resistance, and inductance values across different frequencies and voltages. These disparities should be considered when evaluating the performance of this wirewound resistor and determining its suitability for a particular application.

Conclusion

In this review, we compared the performance of Yageo's FKN200JR-73-0R1 wirewound resistor with the provided statistical benchmark data. Through this analysis, we identified the strengths and weaknesses of the component, helping engineers to determine its applicability to their circuits.

Examining the LCR measurements and comparing them with the statistical benchmark data, the FKN200JR-73-0R1 generally exhibits higher impedance values than the average benchmark values across the tested frequencies. However, the Quality Factors observed in the component are comparable or even lower than the benchmark's minimum values, demonstrating a weaker performance in this area.

When considering the Series Resistance, it is higher than the average values for most tested frequencies in the benchmark data but remains within the typical range. On the other hand, the Series Inductance values generally exceed the average values given in the statistical benchmark, indicating a better performance concerning inductance.

It is important to note that testing at 10 Volts unveiled some missing data for higher frequencies, making it difficult to draw a comprehensive conclusion about the resistor's performance at these levels. That being said, at the tested frequencies, the resistor exhibits performance differences compared to the statistical benchmarks, both positive and negative.

In conclusion, Yageo's FKN200JR-73-0R1 wirewound resistor displays a mixed performance in relation to the given statistical benchmark data. Engineers should carefully consider the resistor's applicability to their circuits based on specific requirements and understand the potential implications in terms of impedance, Quality Factor, Series Resistance, and Series Inductance.
