Chassis Mount Resistors

RER65F4991RC02 is a type of chassis mount resistor, which is designed to tolerate temperatures from -55C to 125C and is equipped with a flame resistant resistor body and epoxy resin coating for additional protection. Chassis mount resistors are typically used in applications requiring mechanical stability, noise reduction, or thermal management. They can also provide additional protection in areas exposed to the elements such as outdoor enclosures or vehicles.

When mounted to a surface, chassis mount resistors work by using their mechanical and thermal properties to dissipate heat generated by the electrical load. Electrical current traveling through the resistor will cause it to heat up and thermally expand. This expansion creates a mechanical force that tensions the resistive wire element and allows it to dissipate the heat. The additional epoxy resin coating provides thermal insulation which further prevents the component from reaching extreme temperatures.

Chassis mount resistors are commonly used in audio and video, computer, power supplies, lighting, and motor control circuits. These resistors can be used to protect against voltage surges, limit current, reduce noise, and as a heat sink. They are widely used in automotive, computer, and industrial control applications as well.

RER65F4991RC02 chassis mount resistors are designed for current limiting applications and their high pulse withstanding capabilities make them ideal for protecting against power supply overcurrent protection, voltage and current surges, and lightning strikes. The resistors provide electrical isolation and ESD protection as well. These resistors operate up to 85C and are UL rated, making them suitable for use in medical, aerospace, and military applications.

The RER65F4991RC02 is constructed with a rugged, thermally conductive epoxy chassis mount resistor body and has a flame retardant rating of UL 94V-0. It features a temperature coefficient of 0.5% per C temperature rise and is designed for low loss operation, making it capable of operating in harsh environmental conditions. Its high pulse withstanding capabilities, electrical isolation, and ESD protection make it well suited for power supply protection and voltage spikes.

The RER65F4991RC02 chassis mount resistor is an ideal choice for applications where heat dissipation, noise reduction, and mechanical stability are required. It provides electrical isolation and ESD protection for automotive, computer, and industrial control applications as well as protection against voltage surges, current limiting, and lightning strikes.
