Chassis Mount Resistors

Chassis mount resistors, also known as screened resistors, are a type of electronic component that is placed on its own support frame and connected to a printed circuit board by using connection pins or wires. The resistors act as a current limiting or voltage dividing element to reduce the magnitude of the current flowing through the circuit and to provide additional resistance to the system. Commonly used in automotive and lighting applications, chassis mount resistors are designed to operate within a given operating temperature range and to maintain their accuracy when subjected to extreme environmental conditions.

RER40F4020RCSL Application Field and Working Principles

The RER40F4020RCSL is a high-power, 25 watt, chassis mount resistor with a resistive element of 40 MΩ and a rated voltage of 2500 Volts. It is constructed with a brass body which offers increased performance in terms of heat dissipation and accuracy when compared to conventional resistor components. The resistor has a temperature coefficient of ±100 ppm/°C and is rated for operation between -55°C and 125°C.

The resistor works by providing an electrical resistance between two points of a circuit. This limits the current flowing through the circuit as well as providing a stable load for the system. The resistance of a resistor is dependent on the materials used and the design of the component itself. For the RER40F4020RCSL, the solid-core wirewound construction is designed to offer superior performance when used in harsh environments or in systems with high switch-off frequencies.

The RER40F4020RCSL is designed for a wide range of applications, including automotive, lighting, military electronics, and space. The component can be used for the protection of electronic components in circuits subject to high load or excessive current flow, as well as for the adjustment of current or voltage levels in power circuits. Furthermore, the resistor is RoHS compliant and comes fully screened for its full rated power and temperature range.

The versatility of the RER40F4020RCSL makes it an ideal choice for applications which require a high-quality, durable, and reliable resistor with wide operating temperature range. The results include better performance, increased reliability and a longer lifespan. The component can also be used as part of a machine safety system to protect against powered objects and other hazardous conditions.
