Physical Data
CONSTRUCTION
A high purity ceramic substrate is assembled with interference fit end caps to which are welded the termination
wires. The resistive element is wound on the substrate and welded to the caps; the vitreous enamel protective
coating is then applied.
TERMINATIONS
Material: Copper clad steel wire, nickel plated and solder-coated.
Length: W23’s and W24’s are not supplied on tape. Minimum length is 30mm.
MARKING
The resistors are legend marked with type reference, resistance value and tolerance.
SOLVENT RESISTANCE
The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed
circuits.
