Power Metal Film Resistors
FEATURES
• High power in small packages (1 W/0207 size to
3 W/0617 size)
• Different lead materials for different applications
• Defined interruption behaviour
• Lead (Pb)-free solder contacts
• Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
• Compatible with “Restriction of the use of Hazardous
Substances” (RoHS) directive 2002/95/EC (issue 2004)
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”.

MARKING
The nominal resistance and tolerance are marked on the
resistor using four colored bands in accordance with IEC
publication 60062, “Color codes for fixed resistors”.
OUTLINES
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 60 294”).

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the
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.
The tests are carried out in accordance with IEC publication
60068-2, “Recommended basic climatic and mechanical
robustness testing procedure for electronic components” and
under standard atmospheric conditions according to

In the Test Procedures and Requirements table, tests
and requirements are listed with reference to the relevant
clauses of “IEC publications 60115-1 and 60 068-2”; 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.
All soldering tests are performed with mildly activated flux.
