Power Resistor Fundamentals

The device designed for limiting the flow of current is known as a resistor. Resistors designed for high power applications are referred to as power resistors.

Following are the typical features of such resistors:

• Manufactured using cermet thick film technology
• High power ratings from 5 to 50 Watt
• High overload capabilities
• High insulation
• High thermal capacity
• Housed in aluminum

The popular categories of power resistors are metal clad braking, silicon-coated resistors, and other customized resistors. Also, refer to resistor basics for more information about discrete resistors.
