CONSTRUCTION:
The Cermatox® sintered oxide based resistive thick film is fired
onto the surface of a high quality ceramic onto which turned
brass end caps are pressed. A helical cut is made into the film
to adjust its ohmic value and finally a sleeve is fitted to provide
mechanical protection and electrical insulation. Resistors for use
in oil or SF6 can be supplied with a lacquer protection instead
of the sleeve.
TERMINATIONS:
Three styles of termination are available to permit resistors to
be screwed together in a series chain, with the end members
having axial wires for soldering.
Wire Terminations: Styles D and KU. See illustration.
Material: Solder-coated copper wire.
Screw Terminations: Styles D and KU. See illustration.
Material: Turned brass.
Screw Thread: All caps are tapped UNF-10 x 4.2 deep. UNF-
10 is 32 TPI, 60° thread angle 4.72±0.07 mm outside diameter,
3.83 mm core diameter.
Coupling Stud: All KU & TU resistors are supplied with 8 mm
long screwed brass studs.
MARKING:
Type reference, resistance value, tolerance and data code are
legend marked.
SOLVENT RESISTANCE:
The lacquer and protective sleeve provide excellent resistance
to all normal industrial cleaning solvents suitable for printed
circuits.
