When you need the highest
quality wirewound axial termi-
nal resistors available, choose
Ohmite’s 90 Series resistors.
They are manufactured by
a unique process that molds
the vitreous enamel over the
resistive element, 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 enam-
el 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.
Fea tures
• Molded Construction provides
consistent shape and size
(Permits mounting in clips which
extends power rating).
• Meets MIL-R-26 requirements
for insulated resistors.
• All-welded construction.
• Flame resistant lead free vitre-
ous enamel coating.
• Higher ratings in smaller sizes.
• Heat sink mounting clips avail-
able.
90 Series
Lead Free Vitreous enamel Molded
axial term. Wirewound, 5% tolerance standard
