This document describes a wirewound resistor from Vishay Dale, which features all welded construction, molded encapsulation, wraparound terminations, excellent stability at different environmental conditions, high power ratings (up to 3 W), superior surge capability, available non-inductive styles with Ayrton-Perry winding (WSC in lieu of WSN, maximum resistance is one-half WSC range), and AEC-Q200 qualified versions. It is also compliant to RoHS Directive 2002/95/EC.
The Vishay WSC and WSN series are precision surface‑mount wire‑wound resistors with welded construction, molded encapsulation and wrap‑around terminations. They are offered in various power ratings up to 3 W, with options for non‑inductive Ayrton‑Perry winding and RoHS‑compliant versions.
The datasheet provides detailed electrical specifications, dimensional drawings, temperature derating curves, performance test limits and packaging information for each model (e.g., WSC01/2, WSC0001, WSC2515, WSC4527, WSC6927). Contact information and legal disclaimer are also included.
