High Ohmic/High Voltage Resistors
FEATURES
These resistors meet the safety requirements of:
“UL1676” (range 510 k
”IEC 60065”
”EN60065”
“BS60065” (U.K.)
“VDE 0860” (Germany)
“CQC” (China)
High pulse loading capability
Small size.
to 11 M
)
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.
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,
“IEC 60068-2-45”.
