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