Chassis Mount Resistors are amongst the most significant electrotechnical components used in numerous appliances. In particular, the RER75F1R87RCSL is a considerable resistor type which finds its substantial applications and is created with its own special working principle.

The RER75F1R87RCSL is a kind of resistor with a rated power of 75W and a resistance of 1R 87R. This type of resistor is notable for its compact size and its high maximum dielectric strength which can go up to 4000V. This resistor is widely used for overload and short-circuit protection of motor and actuator wiring. Another significant application of this resistor is as chokes and dampers in engine and machine vibrator circuits.

The RER75F1R87RCSL has a distinctive construction. To be specific, it is designed as a hermetically sealed cylindrical tube that is made from stainless steel. The resistor is made up of uncoated wafers of molybdenum and molybdenum-zinc which form a helix inside the tube. These wafers are chosen for their excellent heat resistance and thermal conductivity, which enable element temperatures to be kept 3-4ºC lower than the surrounding temperature. In addition, it has films of silicone rubber between the layers which serve to act as a bonding agent while providing insulation.

As for working principle of the RER75F1R87RCSL, it is based on Joule Heat Effects. In simpler terms, this design distributes an electrical current along its successive loops of metal and then collides the current against its resistor to elicit Joule heating. The resistor then produces heat as a result of the collisions, which is conducted through its metallic shell. This heat is eventually dissipated by means of its fins and thus the resistor can work without any need to draw additional energy from the connected device.

Overall, the RER75F1R87RCSL is an important type of chassis mount resistor of considerable size and high output power. It is designed with hermetic sealing and composed of molybdenum and molybdenum-zinc wafers. This resistor features a unique construction with silicone rubber interlayers for insulation and bonding and is ideal for motor and actuator wiring protection as well as engine and machine vibrator circuits. In addition, the RER75F1R87RCSL is based on Joule Heat Effects, which enable it to work without any additional external energy sources.
