Construction

Thin film material is sputtered onto high grade ceramic rods. Nickel

plated steel caps are force fitted and the termination wires are

welded to the caps. The value is obtained by a helical cut in the

film and finally the resistor body is protected by a cement protection

applied so that the terminations remain completely clear.

Terminations

Material

Solder-coated copper wire.

Strength

The terminations meet the requirements of

IEC 68.21.

Solderability

The terminations meet the requirements of

IEC 115-1, Clause 4.17.3.2.

Marking

1% tolerance resistors are color coded with 5 bands. 2%

and 5% tolerance have 4. IEC 62 colors are used.

Solvent Resistance

The body protection and marking are resistant to all normal

industrial cleaning solvents suitable for printed circuits.
