Through Hole Resistors - RLR20C6801GRRE6

Through hole or axial resistors are the standard most widely used type of resistor. These resistors feature leads, or wires, on each end that are inserted through holes drilled into the circuit board to secure the component in place. Through-hole resistors usually have a cylindrical ceramic core, with an insulating coating covered by a colored banding to denote the resistance value. Depending on the size and wattage of the resistor, a cement coating may also be applied for additional insulation and heat dissipation.

The RLR20C6801GRRE6 resistor series is a high precision through hole resistor from Bourns. It is a rectangular, slate gray body, with silvered terminals. This series has a resistance range of 0.001 ohm to 10M ohm, with power ratings of 0.05W to 1W. It offers low resistance tolerance and temperature coefficient of resistance (TCR) for high precision applications. The series features a compact design with an industry standard 0.2in x 0.4in (5.08mm x 10.16mm) footprint and the RLR20C6801GRRE6 series has EX ratings for leakage current.

Applications

The RLR20C6801GRRE6 series is ideal for applications where accurate and reliable signal levels, such as power supplies, medical instrumentation, sensing circuits, and motor control. It can also be used in applications operating at higher temperatures and environments. In addition, these resistors feature a low hysteresis which is ideal for test instrumentation and control systems. Other applications include high frequency switching, electronics shelf, data acquisition system, and lighting.

Working Principle

The principle of a resistor is based on the flow of electricity through it and the magnitude of the current is mainly affected by the resistance. The RLR20C6801GRRE6 resistor works on the principle of Ohm’s law, which states that the current through a resistor is inversely proportional to its resistance. This means that with higher resistance the current will be lower and vice versa while voltage will remain constant.

The resistance value of this series is stable over temperature, thanks to the design and construction. It is typically constructed from tantalum, thick film, or composition material, providing good thermal stability and low inductance. In addition, it uses four polyimide terminations for enhanced mechanical strength.
