Jumper Resistors
WL4
• Insulated body allows WL4 to be
passed over tracks without short
circuiting
• ^{Can be tape mounted for auto-insertion}
machines
• ^{Removes the need for double sided PC}
boards in some cases

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.
