TTE – High Power Resistors

描述

Designing with High Power Resistors

High power resistors are used to dissipate unwanted electrical energy, or as resistive heaters for the deliberate generation of heat. They are often designed for mounting onto a heatsink or housing surface to maximise thermal transfer away from the resistor. Designing with high power resistors requires an appreciation of the methods of thermal management.

Standard semiconductor packages may be used for power ratings in the 10s of watts, and these are ideal for compact solutions as snubbers, high current sense and automotive actuator drive.

For higher powers into the 100s of watts, larger off-PCB products are available. TT Electronics introduced thick film on steel technology for resistive heaters and power resistors, and continues to lead with high reliability designs for the industrial and aerospace sectors.
