Note

Exemptions may apply.

Notes

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

as follows:

or maximum working voltage, whichever is less.

summary of the effects of using the PTF product at the more common combinations of power rating and case size, as well as quantifies the

load life stability under those conditions.
