1. Resistive Element
All resistor types have resistance alloy wind-
ing on a braided fiberglass substrate. Inter-
mediate silicone coatings are used to en-
hance 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.
3. Encapsulation
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.
4. Marking
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
wirewound construction. A fifth band, blue
in color, is used for flameproof identifica-
tion.
