1. Resistive Element
SPECIFICATIONS:
IRC Type
All resistor types have resistance alloy
winding on a braided fiberglass substrate.
Intermediate silicone coatings are used to
enhance processibility and to provide pro-
tection to the resistive element.

2. Termination
The SPH and SPF resistors are terminated
using an alloy coated copper flashed steel
lead welded to a cap of the same material.
This termination assembly is mechanically
crimped, utilizing an improved crimp design,
to the resistive element.

3. Encapsulation
√PR
√PR
The SPH and SPF are encapsulated utiliz-
ing a compression molded phenolic plastic
material. The SPF has a flame-resistance
coating applied over the resistive element
to provide flammability protection when
destructive overloads may occur.

All products are marked utilizing heat and
solvent resistant color code bands consis-
tent with EIA/MIL requirements. The first
band is double width to designate wire-
wound construction. A fifth band, blue in
color, is used for flameproof identification.
