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
Strength
Solderability
Copper clad steel wire, nickel plated and solder-coated.
The terminations meet the requirements of IEC 68.2.21.
The terminations meet the requirements of IEC 115-1,–
Clause 4.17.3.2.
W23’s and W24’s are not supplied on tape.
Minimum lead length is 30 mm.
Length
MARKING
The resistors are legend marked with type reference, resistance value and tolerance.
Values are marked in accordance with IEC 62.
SOLVENT RESISTANCE
The body protection and marking are resistant to all normal industrial cleaning
solvents suitable for printed circuits.
