Electrical Data
1. Resistive Element
All resistor types have resistance alloy
winding on a braided fiberglass substrate.
Intermediate silicone coatings are used
to enhance processibility and to provide
protection 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.

The SPH and the SPF are encapsulated uti-
lizing 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.

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