A screen-printed protection is then applied and terminal wires are then attached. Terminations The termination wires are tin coated copper. Marking Type reference, resistance value and tolerance are legend marked. The resistance value code conforms to IEC 62. Solvent Resistance The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed circuits.

For some ultra-high voltage applications it is required to immerse the components in oil or SF6 gas or pot them in voidfree silicone compound to reduce corona or surface tracking. The printed protection is suitable for these applications. The axial termination should not be bent closer than twice the diameter of the terminal wire from the resistor body.
