When you need the highest quality wirewound axial

terminal resistors available, choose Ohmite’s 90

Series resistors.

They are manufactured by a unique process that

molds the vitreous enamel over the resistive ele-

ment, helping to ensure consistent dimensions.

This uniformity permits 90 Series resistors to be

mounted in clips, creating a heat-sinking benefit (see

next page).

The durable vitreous enamel coating, which is totally

lead free, permits the 90 Series resistors to maintain

a hard coating while operating at high temperatures.

Mechanical integrity is enhanced by the all-welded

construction.
