Construction
Ceramic rods are coated with a metal film and plated steel
caps are force fitted. A helical cut is used to adjust the film to
its final value.
Termination wires are welded to the caps and the resistor is
protected with a specially formulated epoxy coating.
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
