DESIGN TOOLS (click logo to get started)

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.

• Follow link to Overview of Automotive Grade Products for more details: www.vishay.com/doc?49924.

(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.
