FEATURES

• Extremely

low

temperature

coefficient

of

resistance

• Molded encapsulation

• Wraparound compliant terminations eliminate

the risk of solder fillet cracking

• Solderable terminations

• Excellent stability at different environmental

conditions

• For axial-leaded product, see Vishay Dale’s

• Material categorization: For definitions of compliance

Note



Exemptions may apply.

Notes

• Marking: Print-marked-model, value, tolerance, TC, date code.

• DSCC has created a drawing to support the need for a precision 2012-sized product. Vishay Dale is listed as a resource on this drawing as

follows:.
