Introduction

Chassis Mount Resistors (CMRs), are resistors used to control current or voltage flows in electronic equipment and circuits. They are typically also used for the protection of circuits from over-voltage or over-current, providing resistive related functions in circuit designs. RER70F6R81RC02 is a type of CMR. This paper will introduce the application field and working principle of the product.

Application Field

RER70F6R81RC02 is well suited for switching applications. It is frequently applied to circuits where frequent changes of certain voltages, currents, or powers are required. Typical applications include: variable power supplies, switching supplies, DC/DC converters, high voltage or low noise circuits, motor drive circuits, and other power control and protection circuits. It is also highly suitable for use in complex control and protection systems, including those which monitor the performance of an integrated protection system.

Working Principle

RER70F6R81RC02 is a type of resistive element which is typically formed of two resistors in series. The resistance of the two resistors is different, and each resistor is individually adjustable. This adjustable nature of the resistors makes it possible for users to adjust the resistance to meet their requirements. When the resistors are energized, they attract electrons across the surface of the resistors. This in turn generates a current that passes through the resistors. This current is then used to regulate the voltage or current flow in the circuit.

Conclusion

RER70F6R81RC02 is a type of Chassis Mount Resistor with wide applications in power control and protection circuits. It is composed of two resistors in series with adjustable resistance. The adjustable resistance of the resistors allows users to adjust the current or voltage flows in the circuit. As a result, it is ideal for switching applications.
