High Ohmic/High Voltage Metal Glaze Leaded Resistors

A metal glazed film is deposited on a high grade ceramic

body. After a helical groove has been cut in the resistive

layer, tinned electrolytic copper wires are welded to the

end-caps. The resistors are coated with a light blue lacquer

which

provides

electrical,

mechanical,

and

climatic

protection.

The encapsulation is resistant to all cleaning solvents in

accordance with IEC 60068-2-45.

FEATURES

• Technology: Metal glaze

• High pulse loading capability (up to 7 kV)

• Small size (0207)

• Lead (Pb)-free solder contacts

• Pure tin plating provides compatibility with lead (Pb)-free

and lead containing soldering processes

• Compliant to RoHS Directive 2002/95/EC

• AEC-Q200 qualified

APPLICATIONS

• Where high resistance, high stability and high reliability at

high voltage are required

• High humidity environment

• White goods

• Power supplies
