Bourns PWR Series Surface Mount Wirewound Resistors
Bourns PWR Series Surface Mount Wirewound Resistors are covered by epoxy molded encapsulation, which offers environmental protection for the resistive wire. These resistors feature a high power-to-size ratio and excellent pulse handling capabilities, making them ideal for circuits with inrush currents or surge voltages. The PWR series surface mount resistors are available in both inductive and non-inductive versions, and they offer a wide range of resistance values with a low temperature coefficient. Typical applications include telecommunications, smart meters, and audio equipment.
