Construction
Marking
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.
Type reference, TCR code, resistance value and tolerance
code.
The resistance value marking conforms to IEC 62.
The body protection and marking are resistant to all normal
industrial cleaning fluids suitable for printed circuits.

Resistors can be supplied matched for tolerance and TCR
down to ±0.005% and ±1ppm/°C, respectively, either as
separate resistors or pre-assembled and encapsulated within a
plastic box.
The individual resistors within a set or module can be
manufactured with a tolerance of ±0.01% and a TCR of
±5ppm/°C.
