Construction

A high quality ceramic substrate is assembled with

interference fit end caps to which are welded the element

winding and termination wires. The protection is then applied

to the body, providing an effective seal which is impervious to

moisture, shock, vibration, fungus and salt spray.

Marking

W31 resistors are legend marked with type reference,

resistance value and tolerance. Values are marked in

accordance with IEC 62.

Solvent Resistance

The body and marking are resistant to all normal industrial

Terminations

Material

cleaning solvents suitable for printed circuits.

Solder coated copper.

Strength

The terminations meet the requirements of

IEC 68.2.21.

Flammability

The resistor coating will not burn under any condition of

Solderability

General Note

The terminations meet the requirements of

IEC 115-1, Clause 4.17.3.2.
