Philips Components
Product specification
High ohmic/high voltage resistors
VR25
FEATURES
High pulse loading capability
Small size.
APPLICATIONS
Where high resistance, high
stability and high reliability at high
voltage are required
High humidity environment
White goods
Power supplies.
DESCRIPTION
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”
