Construction
A high purity ceramic rod, with force fit end caps onto which is wound a wire element: or a deposited metal oxide film
(depending on value). The element is fitted into a ceramic case with fireproof insulation cement.
Termination Details
Material
Solderability The terminations meet the requirements of IEC 115-1 Clause 4.17.3.2
Strength The terminations meet the requirements of IEC 86.2.21
The tinned copper lead wires are internally welded to the resistance element end caps.

Marking
Type reference, resistance value and tolerance are legend marked onto the upper surface.
Flammability
The resistor will not burn or emit incandescent particles under any condition of applied temperature or
overload.
Solvent resistance
The body protection and marking are resistant to all normal industrial solvents suitable for printed
circuits.
