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
• R_max. = 22 M; U_max. = 1600 V_DC
• 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
