High Ohmic (up to 10 M)/High Voltage (up to 3.5 kV)

Metal Film Leaded Resistors

DESIGN SUPPORT TOOLS

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.

FEATURES

• Technology: metal film

• High pulse loading (up to 10 kV) capability

• Small size (0207/0411)

• Compatible with lead (Pb)-free and lead

containing soldering processes

• Material categorization: for definitions of compliance

APPLICATIONS

• Power supplies

• Electronic ballast

• White goods

• Television

HVR25, HVR37 www.vishay.com Vishay BCcomponents TESTS AND REQUIREMENTS Essentially all tests are carried out in accordance with IEC 60115-1, category 55/155/56 (rated temperature range -55 °C to +155 °C; damp heat, long term, 56 days) and along the lines of IEC 60068-2-xx test method. The tests are carried out under standard atmospheric conditions according to IEC 60068-1, 5.3 unless otherwise specified. In some instances deviations from IEC recommendations were necessary for our method of specifying.
