Axial Terminal / Surface Mount / Heat Sinkable Packaging

Ohmite Manufacturing’s family of High Energy

Wirewound Resistors employ special winding tech-

niques to maximize the effective joule rating of each

resistor. Most wirewound resistors are wound with

the objective of meeting the stated power (watt-

age) rating and keeping cost low through the use

of automatic winding equipment. Typically, manu-

facturers will allow substitution of resistance wire,

depending on material availability. 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 rating and fusing current of a wirewound

resistor, and this is often the reason that the manu-

facturer does not publish a fixed joule rating.

Ohmite High Energy Wirewounds are wound so

as 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 rat-

ing and fusing current for each part number in the

series.

This technique can be applied to any wirewound

product. In order to provide the broadest selection of

packaging, Ohmite has developed standard offerings

in three different package types-axial, SMD, and heat

sinkable. Other sizes and types can be quoted on

request, such as tubular power resistors.
