Chassis Mount Resistors

A RER70F1R30RCSL is a chassis mount resistor, a type of electronic component used for the precise control of voltage, current and power outputs. This particular type of resistor is a non-inductive, wirewound design with a maximum power rating of 70 Watts and resistance tolerance of 1% (standard). This component is typically recommended for applications that require high power ratings, high thermal stability and precise control of resistance.

Application Field

The RER70F1R30RCSL is predominantly used in audio power amplifiers. The 70 Watt power rating makes it a suitable choice for providing a regulated voltage and current to high power transistors and other components. Other applications for this type of resistor include load testing voltage regulators, transient voltage suppressors, voltage references and capacitor discharge circuits. It is also used in car audio systems, solar cell power converters, motor control circuits and other power management systems.

Working Principle

The RER70F1R30RCSL works on the principle of resistive load control. This type of resistor consists of a wirewound element wound around a non-inductive substrate or core material. When a current flows through the resistor, the element opposing this current will create a voltage drop, according to Ohm’s law, resulting in power dissipation determined by the product of the voltage drop and current. The amount of power dissipated depends on the resistance of the resistor, which in turn is determined by the number of turns in the wirewound element and the material used for the core.

By changing the number and material of turns, one can control the power output of the resistor and guarantee stable operation of the electronic device. In addition, the substrate helps to dissipate heat, thus ensuring thermal stability. The non-inductive nature of the substrate further ensures resistance stability and accuracy.

As mentioned, the RER70F1R30RCSL has a resistance tolerance of 1%, which ensures that the resistance remains very stable and accurate over a wide range of operating temperatures. The resistor is designed to withstand extreme temperatures ranging from -65°C to +210°C in order to deliver accurate voltage and current over a wide range of environmental conditions.

Overall, the RER70F1R30RCSL is a well-designed, reliable chassis mount resistor that is suitable for a number of applications. It can ensure high power outputs and precise control of resistance, which makes it ideal for many electronic devices.
