Tin-plated steel caps are force fitted and the Strength: The terminations meet the requirements termination wires are welded to the caps. The value is of IEC 68.2.21 obtained by a helical cut in the film and finally the resistor Solderability: The terminations meet the requirements body is protected by a cement coating. of IEC 115-1 Clause 4.17.3.2 Solvent Resistance Marking The body protection and marking are resistant to all normal 1% tolerance resistors are colour coded with 5 bands. 2% industrial cleaning solvents suitable for printed circuits. and 5% tolerance have 4 bands. IEC62 colours are used. Flammability The resistor coating will not burn under any condition of applied temperature or power overload.
