Construction
The resistance element is deposited on a high purity ceramic
rod. End caps are force fitted and termination wires welded to
the caps. The element is adjusted to the required resistance
value by a helical cut; finally the cement protection is applied
to the resistor body before marking with indelible ink.

Marking
Resistors are colour coded with 4 bands.
IEC 62 colours are used.
Solvent Resistance
The body protection and marking are resistant to all normal
industrial cleaning solvents suitable for printed circuits.
Flammability
The resistors will not burn or emit incandescent particles
under any condition of applied temperature or power
overload.
