Resistive Element

Encapsulation

All resistor types have resistance alloy winding on a braided

fibreglass substrate. Intermediate silicone coatings are used to

enhance processibility and to provide protection to the

resistive element.

The SP20 and SP20F are encapsulated utilizing a compression

molded phenolic plastic material. The SP20F has a flame

resistance coating applied over the resistive element to

provide flammmability protection when destructive overloads

may occur.

Termination

The SP20 and SP20F 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.

Marking

All products are marked utilizing heat and solvent resistant

colour code bands consistent with EIA/MIL requirements. The

first band is double width to designate wirewound

construction. A fifth band, blue in colour, is used for

flameproof identification.

General Note

Welwyn Components reserves the right to make changes in product specification without notice or liability.
