Construction

Termination wires are welded to a very low resistance body.

The body is then protected by a moisture resistance high

dielectric strength coating applied so that the terminations

remain completely clear. This permits a well defined body

length (clean lead to clean lead dimension L).

Materials

Material

Solder-coated copper wire.

Strength

The materials meet the requirements of IEC

68.2.21

Solderability

The terminations meet the requirements of

IEC 115-1, Clause 4.17.3.2

Marking

Resistors are marked with two yellow bands placed centrally

on the body.

Solvent Resistance

The body protection and marking are resistant to all normal

industrial cleaning solvents suitable for printed circuits.
