Product specification
Professional power metal film resistors
PR01/02/03
FEATURES
High power in small packages
Different lead materials for different
applications
Defined interruption behaviour.
APPLICATIONS
All general purpose power
applications.
DESCRIPTION
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
or copper-clad iron are welded to the
end-caps. The resistors are coated with
a red, nonflammable lacquer which
provides electrical, mechanical and
climatic protection. This coating is not
resistant to aggressive fluxes. The
encapsulation is resistant to all
cleaning solvents in accordance with
“MIL-STD-202E, method 215”
, and
“IEC 60068-2-45”
.
