Impedance

In this section, we will thoroughly examine and assess the impedance performance of the Yageo RL2512FK-070R1L Thick Film Resistor, comparing it against the statistical benchmark data provided for components with the same value. To provide an intensive and diligent analysis of the component's impedance characteristics, we will consider its performance at 1 Volt and 10 Volts.

At 1 Volt, the Yageo RL2512FK-070R1L Resistor exhibits an impedance range of 90.43mΩ at 5 Hz to 93.53mΩ at 1 MHz. This performance is slightly below the benchmark average impedance across the entire frequency spectrum, indicating a relatively standard impedance behavior for this thick film resistor. It is crucial to note that at low-frequency ranges, specifically 5 Hz to 500 Hz, the impedance remains fairly constant with minimal fluctuations. This stability can be advantageous for various applications requiring stable impedance values within those frequencies.

When comparing the RL2512FK-070R1L Resistor to the statistical benchmark's minimum impedance values, it can be seen that the component exhibits a higher minimum impedance. Additionally, when comparing the resistor to the benchmark's maximum impedance values, its impedance is lower. This characteristic results in narrowing the overall performance range, which emphasizes the consistent performance profile of the RL2512FK-070R1L Resistor compared to its counterparts.

At 10 Volts, the Yageo RL2512FK-070R1L Resistor demonstrates a distinctive impedance progression, starting at 94.71mΩ at 5 Hz and dropping to a minimum of 78.85mΩ at 150 kHz. Subsequently, the impedance gradually increases up to 93.08mΩ at 900 kHz. It is interesting to note that in the frequency range of 20 kHz to 50 kHz, the RL2512FK-070R1L Resistor's impedance significantly deviates from the benchmark data. This deviation potentially indicates a unique performance characteristic within this specific region, which may have implications for its effective use in certain applications where impedance behavior in the 20 kHz to 50 kHz range is a critical factor.

Resistance

In our comprehensive technical analysis, we evaluated the performance of the Yageo RL2512FK-070R1L resistor by contrasting its measured resistance values against a carefully established statistical benchmark that is composed of resistors with equivalent specifications. It is crucial to measure and compare the resistance of such components precisely to predict their performance effectively and accurately.

As expected, the RL2512FK-070R1L resistor's measured series resistance at 1 Volt reveals consistency in performance across a diverse range of test frequencies. This resistor demonstrates a favorable resistance range, spanning from 90.43m (at 5 Hz) to 90.97m (at 1 MHz), a profile that outshines the average benchmark values: 91.71m (at 5 Hz) to 93.43m (at 1 MHz). This narrower resistance spread implies a comparatively better performance of the RL2512FK-070R1L over the other benchmarked components in the test.

When assessing the measurements at 10 Volts, the RL2512FK-070R1L maintains its remarkable performance against the benchmark by displaying reduced series resistance and smaller variations across the entire gamut of test frequencies. Most notably, at 50 kHz, the RL2512FK-070R1L resistor showcases a series resistance of only 82.08m, significantly outstripping the benchmark average resistance of 92.15m at an identical frequency. Moreover, the collected data indicates an almost unwavering performance between 450 kHz and 600 kHz, which further underlines the resistor's commendable attributes.

In conclusion, the Yageo RL2512FK-070R1L resistor exhibits superb resistance performance when pitted against the statistical benchmark established by other components with the same nominal value across a wide range of test frequencies. This level of consistency and preciseness makes the RL2512FK-070R1L an ideal choice for engineers seeking exemplary stability and efficiency in their electronic circuits where accurate and stable resistors play a critical role in circuit performance.

Inductance

The performance of the Yageo RL2512FK-070R1L is thoroughly evaluated for inductance, unveiling insights by comparing its detailed LCR measurements taken at 1 Volt and 10 Volts to a comprehensive statistical benchmark generated from similar components possessing the identical inductance value.

At 1 Volt, under the test frequency of 5Hz, the RL2512FK-070R1L demonstrates a series inductance of 3.64μH, comfortably fitting within the calculated benchmark range of 1.638μH to 5.906μH. With regard to the average benchmark value of 3.411μH, however, it is situated on the higher side. Similarly, the series inductance of 895.5nH, presented at a 10Hz test frequency, aligns well within the comprehensive benchmark range of 329nH to 1.435μH and is above the average benchmark value of 868.9nH.

The RL2512FK-070R1L exhibits a decrease in series inductance values as the test frequency is amplified, often closely mimicking or slightly falling below the established statistical benchmark averages. For example, a series inductance value of 3.507nH is reported at the 500kHz test frequency, which is comparatively below the benchmark's average value of 6.249nH. Also, at the 1MHz test frequency, with the RL2512FK-070R1L featuring a series inductance of 3.471nH, its value leans towards the lower benchmark limit (1.238nH to 35.29nH) and is notably below the average value of 6.152nH.

With relatively sparse data available for LCR measurements at 10 Volts, a comprehensive evaluation can prove to be challenging. Nonetheless, there are a few noteworthy observations. In particular, the series inductance at 5Hz sees a significant growth to 89.15μH, surpassing the ranges of the 1 Volt benchmarks. Moreover, at a frequency of 100kHz, an inductance of 962.9pH is recorded for the RL2512FK-070R1L, often tending to drift near the lower limit of statistical benchmark values at such elevated frequencies.

During this evaluation, it becomes evident that the Yageo RL2512FK-070R1L demonstrates varying levels of inductance performance in comparison to the available benchmark data. At lower test frequencies, it yields performance close to or even slightly above benchmark averages. As the test frequency rises, however, the values of inductance tend to deteriorate, potentially affecting `certain high-frequency applications. Consequently, further scrutiny, incorporating additional parameters, is highly recommended before integrating this component into specific circuits.

For example, at a frequency of 700 kHz, the RL2512FK-070R1L records series resistance value of 90.85 mOhms, whereas the benchmark data reflects an average of 93.13 mOhms.

Regarding series inductance, the RL2512FK-070R1L shows exceptional performance at lower frequencies (5 Hz - 20 kHz). Specifically, in this range, the RL2512FK-070R1L exhibits remarkably higher levels of inductance compared to the benchmark group. The inductance displayed by the RL2512FK-070R1L is 3.64 μHenries at 5 Hz, which is notably higher than the benchmark group, which has an average of 3.411 μHenries.

Conclusion

In this review, we have analysed the performance of the Yageo RL2512FK-070R1L thick film resistor and compared it to a statistical benchmark formed from other components with the same value. After examining the data, we have drawn several definitive conclusions.

At the tested frequencies, the RL2512FK-070R1L shows Impedance and Series Resistance values that are close to the average benchmark. However, at specific points, such as between 20 kHz and 50 kHz, its impedance deviates from the expected average values. The series inductance at 1 Volt test also has minor deviations at certain frequencies (e.g., 900 kHz to 1 Mhz), but overall performance is within standard bounds.

On the other hand, when performing LCR tests at 10 Volts, RL2512FK-070R1L demonstrates a much more fluctuating performance deviating from the benchmark at specific frequencies. A noteworthy point is the unavailability of data for the resistor at frequencies between 750 kHz and 1 MHz. Further investigation is necessary to understand the correlations and impacts of these deviations on the performance of the resistor.

In conclusion, the Yageo RL2512FK-070R1L offers a stable performance that falls within standard expectations for the majority of tested frequencies. However, the somewhat fluctuating performance at 10 Volts, especially in higher frequency tests between 75 kHz and 1 MHz, may raise concerns when considering this resistor for high-reliability applications or circuits with specific requirements. In such cases, it would be prudent to thoroughly consider the specifications and applications for which the RL2512FK-070R1L will be used. Furthermore, investigating alternative products or conducting further testing may also be advisable.
