HVR25, HVR37
Vishay BCcomponents
High Ohmic/High Voltage Metal Film Leaded Resistors
FEATURES
• Metal film technology
• High pulse loading (up to 10 kV) capability
• Small size (0207/0411)
• Compatible with lead (Pb)-free and lead containing
soldering processes
• Compliant to RoHS directive 2002/95/EC
A homogenous film of metal alloy 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 blue,
non-flammable lacquer, which provides electrical,
mechanical, and climatic protection.
APPLICATIONS
• Power supplies
• Electronic ballast
• White goods
• Television
