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.
Note: Due to space restrictions, parts are stamped with wattage ratings reduced to the
nearest whole number. The actual wattage ratings are as published in this catalog.

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.
