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.
