Ohmite Manufacturing’s family
of High Energy Wirewound
Resistors employ special
winding techniques to maxi-
mize the effective joule rating
of each resistor. Most wire-
wound resistors are wound
with the objective of meeting
the stated power (wattage)
rating and keeping cost low
through the use of automatic
winding equipment. Typically,
manufacturers will allow sub-
stitution of resistance wire,

depending on material avail-
ability. On tight tolerance
wirewounds some type of
abrasive adjustment to the
resistance wire is often used
to maximize production yields.
Both of these procedures can
adversely affect the joule rat-
ing and fusing current of a
wirewound resistor, and this
is often the reason that the
manufacturer does not publish
a fixed joule rating.

RoHS compliant product available; Add “E” suffix to part number to specify.
Wirewounds are hand
wound in order to maintain
the tightest possible pitch
(space between windings) and
thereby maximize the mass of
the resistive element. Since no
wire substitutions are allowed,
and no abrasive adjusting is
permitted in this family, Ohmite
can publish a fixed joule rating
and fusing current for each
