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.
