Electronic engineers should weigh this pertinent information when determining whether the CW005R1000JE73 Resistor performs optimally for various applications under diverse voltage conditions.

In conclusion, the comparison of the Vishay Dale CW005R1000JE73 Resistor's impedance performance against the statistical benchmark serves to illuminate its consistently higher impedance provision. Consequently, this particular resistor may prove to be better suited for applications necessitating increased impedance, particularly within the stipulated frequency range. Furthermore, electronic engineers should pay scrupulous attention to the voltage-dependent behavior of this Resistor in their circuit designs to ensure optimal performance, bearing in mind the considerable differences observed between 1 Volt and 10 Volt test scenarios.

Resistance

In this section, we will undertake an in-depth examination of the resistance performance of the Vishay Dale's wirewound resistor with part number CW005R1000JE73. Our primary focus will be to evaluate the deviation from the nominal resistance of 100 milliohms (100m) within a tolerance of ±5%, considering the possible impact that the observed deviation could pose on the targeted application. The analysis will involve evaluating data obtained from LCR measurements taken at various test frequencies spanning between 5 Hz and 1 MHz, and test voltages of 1 and 10 volts. The results will be compared to a pre-established statistical benchmark to understand the performance characteristics of the resistor and ascertain if it stays within the manufacturer's specifications.

LCR measurements of the CW005R1000JE73 resistor, taken at 1 volt, indicate a relatively small deviation from the nominal resistance value. This deviation appears to grow more pronounced as test frequencies increase, ranging from a measurement of 100.9 milliohms at 5 Hz up to the maximum observed value of 105.5 milliohms at 1 MHz. Given that the acceptable deviation as per the tolerance specification is ±5%, the resistor's performance can still be considered acceptable within the specified limits.

In the case of higher test voltages of 10 volts, some inconsistencies are reported within lower frequency measurements. Furthermore, there is a dearth of specific detail for certain frequencies above 600 kHz in the benchmark data, which restricts the scope to comprehensively analyze the resistor's performance in that range.

Nevertheless, within the available data range, at a test frequency of 50 kHz and a voltage of 10 volts, the CW005R1000JE73 wirewound resistor exhibits a marked jump in resistance, measuring 92.78 milliohms. This observation leads us to deduce that the resistor demonstrates a clear tendency toward greater deviation at higher frequencies and voltages when compared against the statistical benchmark.

Keeping in mind the findings from our resistance analysis, it is of utmost importance to consider the resistance deviation exhibited by the CW005R1000JE73 wirewound resistor in relation to the intended circuit implementation. Depending on the specific engineering application and the environment in which the resistor is deployed, the gradual increase in resistance values as the testing frequency rises might still be manageable. However, it is crucial to evaluate the potential impact of these deviations before choosing this resistor in order to ensure optimal circuit performance and reliability.

Inductance

The CW005R1000JE73 exhibits a series inductance of 4.696 µH at the relatively low test frequency of 5 Hz, which is notably higher than the average benchmark of 3.411 µH. This increased inductance, although not ideal for low-frequency circuits, is indicative of the component's potential capability in more challenging, higher-frequency applications. Nevertheless, as the test frequency increases, the observed disparity between the CW005R1000JE73's inductance and the benchmark narrows, revealing its greater adaptability and performance at higher frequency ranges. For example, at 50 Hz, it records an inductance of 602.7 nH, which closely mirrors the average benchmark of 598.7 nH.

As the frequency continues to increase, the statistical deviation observed in the CW005R1000JE73's inductance begins to diminish. By the time we reach 1 kHz, it records 34.21 nH, a value only slightly above the benchmark's average of 8.074 nH. This resistor's adaptability to higher frequencies is further showcased when tested at 5 kHz, as the inductance values remain well within the acceptable range and demonstrate consistent performance.

In extremely high-frequency scenarios, the CW005R1000JE73 maintains a commendable performance trend, with no detrimental effects on inductance values. To illustrate this, let's consider a datum point at 800 kHz: the observed 35.4 nH inductance demonstrates a performance metric that is not far off from the benchmark's average value of 6.211 nH. This means that the CW005R1000JE73 demonstrates remarkable adaptability when faced with even the most demanding and intricate circuit designs operating at high frequencies.

Overall, the CW005R1000JE73 presents itself as a suitable component for use across a diverse range of applications, particularly in higher-frequency domains. Its performance and adaptability make it a strong candidate for incorporation into designs where inductance considerations are crucial to maintain proper operational integrity and ensure reliable circuit performance.
