Welwyn Components

Construction

Thick film material is fired on to high grade ceramic rods.

Tin 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 given a

high temperature protective coating.

Terminations

Material

Solder coated copper wire.

Strength

The terminations satisfy the requirements of

IEC 68.2.21.

Solderability The terminations meet the requirements of

IEC 115-1, Clause 4.17.3.2.

Marking

1% tolerance resistors are colour coded with 5 bands, 2%

and 5% tolerance have 4, IEC 62 colours are used.

Solvent Resistance

The body protection and marking are resistant to all normal

industrial cleaning fluids suitable for printed circuit boards.
