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 60294”).
MOUNTING
The resistors are suitable for processing on automatic
insertion equipment and cutting and bending machines.

FUNCTIONAL DESCRIPTION
PRODUCT CHARACTERIZATION
Standard values of nominal resistance are taken from the E96/E24 series for resistors with a tolerance of ± 1 % or ± 5 %.
The values of the E96/E24 series are in accordance with “IEC publication 60063”.
