CONSTRUCTION
A metal film is deposited onto a high quality ceramic
former. Nickel-plated steel caps are force fitted to the
former and termination wires are welded to the caps.
The resistor is adjusted to value by a helical cut in
the film and the body is protected with a specially
formulated epoxy coating.
TERMINATIONS
Material
Strength
Solder coated copper wire
The terminations meet the
requirements of IEC 68.2.21.
The terminations meet the
requirements of IEC 115-1,
Clause 4.17.3.2.
Solderability
MARKING
Type reference, TCR code, resistance value and
tolerance code.
The resistance values conform to IEC 62.
SOLVENT RESISTANCE
The body protection and marking are resistant to all
normal industrial cleaning solvents suitable for
printed circuits.
