PHYSICAL DATA:
Construction:
The metal film is deposited on a high purity ceramic rod. End caps
are force fitted and termination wires welded to the caps. The
resistive film is adjusted to the required value by a helical cut;
finally the cement protection is applied to the resistor body and
marked with indelible ink.
Termination:
Solder-coated copper wire.

Marking:
Resistors are color coded with five bands. Four of the bands are
used to indicate value and tolerance, with IEC 62 colors being
used. A fifth yellow band denotes constant voltage fusibility.
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.
