90 Series

Lead Free Vitreous Enamel Molded

Axial Term. Wirewound, 5% Tolerance Standard

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.

F e at u r e S

• Molded Construction provides consistent shape

and size (Permits mounting in clips which extends

power rating).

• Meets MIL-R-26 requirements for insulated resis-

tors.

• All-welded construction.

• Flame resistant lead free vitreous enamel coating.

• Higher ratings in smaller sizes.

• Heat sink mounting clips available.

• RoHS compliant; add “E” suffix to part number to

specify.
