Construction
Thin film material is sputtered on to high grade ceramic rods.
Nickel plated steel caps are force fitted and the termination
wires are welded to the caps. The value is obtained by a
helical cut in the film and finally the resistor body is protected
by a cement protection applied so that the terminations
remain completely clear.
Marking
1% tolerance resistors are colour coded with 5 bands.
2% and 5% tolerance have 4. Band IEC 62 colours are used.
