Construction Marking
A metal film is deposited onto a high quality ceramic former. Type reference, TCR code, resistance value and
Nickel-plated steel caps are force fitted to the former and tolerance code.
termination wires are welded to the caps.
The resistance values conform to IEC 62.
The resistor is adjusted to value by a helical cut in the film
and the body is protected with a specially formulated epoxy Solvent Resistance
coating. The body protection and marking are resistant to all normal
industrial cleaning solvents suitable for printed circuits.
Terminations
Material Solder coated copper wire
Strength The terminations meet the requirements of
IEC 68.2.21.
Solderability The terminations meet the requirements of
IEC 115-1, Clause 4.17.3.2.
