Through Hole Resistors

Introduction

Through Hole Resistors are widely used in the electrical engineering and circuitry designs. This article will focus on the RLR07C2002FPRSL model of Through Hole Resistor, a robust and compact design provided by Susumu Manufacturing, Japan. It encompasses the application field and working principle of the model.

Application Field

The RLR07C2002FPRSL Through Hole Resistor model is a non-inductive formulation, especially designed to meet the needs of power line filtering, industrial, automotive, communication and military applications. It provides advanced protection against inductive voltage, eliminating the risks of potential breakdowns due to line distortions. Its robustness allows for withstanding a rated voltage of 500V, and its small construction allows for a direct fit into all kinds of integrated circuits. The model delivers a stable resistance with a Accuracy Level of ±70mΩ at 25°C, and has an insulation resistance of 100MΩ min. The model’s rated power dissipation is 2W with a rated load of 10A. The profile allows for a Low Stacking Height of 7.8-8.5mm, with an overall size of 7.2-8.0mm. The RLR07C2002FPRSL Through Hole Resistor is offered in options of ±25ppm, ±50ppm and ±100ppm with tolerances ranging from ±1%to 0.1%.

Working Principle

The RLR07C2002FPRSL Through Hole Resistor operates by maintaining a constant resistance, irrespective of the amount of current or ΔV/ΔT fluctuations it is exposed to. This is done via three general approaches. The first involves "dynamic resistance". This occurs through the addition of reactive elements, such as inductors and capacitors, to compensate for the impedance changes caused by thermal fluctuations. This allows for a more precise and stable resistance which can match the demands of various applications.The second approach, known as "self-biasing", works by utilizing the internal material characteristics of the resistor to account for the thermal changes. In this method, the material\'s intrinsic thermal conductivity and electrical resistivity are utilized to produce a consistent resistance regardless of the temperature.The third approach is "load line control". This works by altering the output ratio of the resistor in response to external conditions. It utilizes inducer-capacitor feedback control to ensure a stable behavior in the output ratio.

Conclusion

The RLR07C2002FPRSL Through Hole Resistor, with its reliable engineering and design, offers robust performance for myriad of applications, and is a great choice for those who seek a steady and precise resistance for their designs. Its stable resistance, plus its long-term reliability and operational temperature range of -55°C to +150°C, makes it a reliable choice with a guaranteed performance.
