Power Metal Film Resistors
FEATURES
• High power in small packages
• Different lead materials for different applications
• Defined interruption behaviour.
APPLICATIONS
• All general purpose power applications
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”.

The length of the body (L1) is measured by inserting the leads
into holes of two identical gauge plates and moving these
plates parallel to each other until the resistor body is clamped
without deformation (“IEC publication 60294”).

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the
and under standard atmospheric conditions according to
“IEC 60068-1”, subclause 5.3.
schedule
of
“IEC publication
60115-1”,
category
LCT/UCT/56 (rated temperature range: Lower Category
Temperature, Upper Category Temperature; damp heat,
long term, 56 days). The testing also covers the
requirements specified by EIA and EIAJ.
In the Test Procedures and Requirements table, tests and
requirements are listed with reference to the relevant
clauses of “IEC publications 60115-1 and 60068-2”; a short
description of the test procedure is also given. In some
instances deviations from the IEC recommendations were
necessary for our method of specifying.
The tests are carried out in accordance with IEC publication
60068-2, “Recommended basic climatic and mechanical
robustness testing procedure for electronic components”
All soldering tests are performed with mildly activated flux.
