NFR25/25H
Vishay BCcomponents
Fusible, Non-Flammable Resistors
FEATURES
Overload protection without risk of fire
Wide range of overload currents.
APPLICATIONS
Audio
Video.
A homogeneous film of metal alloy is deposited on a high
grade ceramic body. After a helical groove has been cut in
the resistive layer, tinned connecting wires of electrolytic
copper are welded to the end-caps. The resistors are coated
with a grey, flame retardant 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”.
Note

Ohmic values (other than resistance range) are available on request.
