Construction
Cap and lead assemblies are fitted to a high purity ceramic
substrate. The resistive element is wound onto the substrate
and welded to the caps. The wound rod is then moulded and
fitted into an aluminium housing to give optimum stability
and reliability.
Marking
The resistors are legend marked with type reference,
resistance value and tolerance which will withstand all
accepted industrial cleaning fluids. Values are marked in
accordance with IEC 62.
Terminations
Material
Strength
Solderability
Solder dipped, copper clad steel wire.
The terminations meet the requirements of
IEC 68.2.21
The terminations meet the requirements of
IEC 115-1, Clause 4.17.3.2
