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 Ayrton-
Perry winding (WSN in lieu of WSC, maximum
resistance is one-half WSC range)
• AEC-Q200 qualified
(1)
• Material categorization: for definitions of
compliance please see
www.vishay.com/doc?99912
Notes
• This datasheet provides information about parts that are RoHS-compliant and / or parts that are non-RoHS-compliant. For example, parts
with lead (Pb) terminations are not RoHS-compliant. Please see the information / tables in this datasheet for details.

(1)
Flame retardance test may not be applicable to some resistor technologies.
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)
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
(2)
As of February 19, 2016, the WSC0001 was obsoleted by PCN-DR-013-2015; the WSC2515 is a drop-in replacement. You may contact your sales
representative or submit an inquiry via
ww2bresistors@vishay.com
for supporting information.
Note
• Packaging code: EB (lead (Pb)-free) and TB (tin / lead) are non-standard packaging codes designating 1000 piece reels. These non-standard
packaging codes are identical to our standard EA (lead (Pb)-free) and TA (tin / lead), except that they have a package quantity of 1000 pieces.
