RWISRWNS

SMD Power Wirewound Resistors

Precision SMD wirewound resistors with all welded construction, epoxy molded encapsulation, and wraparound solderable terminations.

Overview

Product Overview

RWIS/RWNS SMD wirewound resistors feature an all welded construction, molded encapsulation, and wraparound solderable terminations. The series offers superior surge capability and excellent stability at different environmental conditions.

The RWIS/RWNS series are SMD Wirewound resistors that come in 5 sizes, from 0.5 Watts to 5 Watts. The epoxy molded construction provides complete environmental protection that allows these resistors to meet a broad range of applications.

The all welded Wirewound construction allows the RWIS/RWNS to perform in High Voltage, High Power and High Pulse requirements. As optional construction, the RWNS products are noninductive version.
