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.

Type reference, TCR code, resistance value and tolerance

code. The resistance value marking conforms to IEC 62.

Termination wires are welded to the caps and the resistor is

protected with a specially formulated epoxy coating.

Solvent Resistance

The body protection and marking are resistant to all normal

industrial cleaning fluids suitable for printed circuits.

Terminations

Material

Solder-coated copper wire.

Strength

The terminations meet the requirements of

IEC 68.2.21

Solderability

General Note

The terminations meet the requirements of

IEC 115-1, Clause 4.17.3.2
