WSC, WSN

Vishay Dale

Wirewound Resistors,

Precision Power, Surface Mount

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 in non-inductive styles with Aryton-

Perry winding (WSN in lieu of WSC, maximum

resistance is one-half WSC range)

•Compliant to RoHS directive 2002/95/EC

Notes

• Part marking: 1/2 W - DALE, value; 1 W - model, value, tolerance, date code; 2 W and 3 W - DALE, model, value, tolerance, date code

(1) 0.1 % and 0.25 % is available on the WSC2515 for 0.499 Ω to 2.5 kΩ range

(2) As of 1/1/2010, the WSC0001 and WSC0002 are molded with thermoplastic in lieu of epoxy. Reference PCN-DR-002-2009 and

PCN-DR-003-2009.

Note

(3) WSC2515 only

* Pb containing terminations are not RoHS compliant, exemptions may apply
