High Ohmic/High Voltage 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 “MIL-STD 202E, method 215” and
“IEC 60068-2-45”.
FEATURES
• These resistors meet the safety requirements of:
“UL1676” (range 510 kΩ to 11 MΩ)
”IEC 60065”
”EN60 065”
“BS60065” (U.K.)
“VDE 0860” (Germany)
“CQC” (China)
• High pulse loading capability
• Small size.
APPLICATIONS
• Where high resistance, high stability and high reliability at
high voltage are required
• Safety component in combination with high voltage
• White goods
• High humidity environment
• Power supplies.
