CONSTRUCTION
The resistor is constructed on top of a high-grade ceramic body. Internal metal electrodes are added at each
end and connected by a resistive glaze. The resistive glaze is covered by a lead -free glass. The composition of
the glaze is adjusted to give the approximately required resistance value. The whole element is cove red by a
protective overcoat. The top of overcoat is marked with the resistance value. Finally, the two external
terminations (Ni/matte tin) are added, as shown in Fig.5.
