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