Cemented wirewound resistors
AC01/03/04/05/07/10/15/20
FEATURES
DESCRIPTION
• High power dissipation in
small volume
The resistor element is a resistive
wire which is wound in a single layer
on a ceramic rod. Metal caps are
pressed over the ends of the rod.
The ends of the resistance wire and
the leads are connected to the caps
by welding. Tinned copper-clad iron
leads with poor heat conductivity are
employed permitting the use of
relatively short leads to obtain stable
mounting without overheating the
solder joint.
• High pulse load handling
capabilities.
APPLICATIONS
• Ballast switching
• Shunt in small electric motors
• Power supplies.
The resistor is coated with a green
silicon cement which is not resistant
to aggressive fluxes. The coating is
non-flammable, will not drip even at
high overloads and is resistant to
most commonly used cleaning
solvents, in accordance with
“MIL-STD-202E” and
“IEC 60068-2-45”.

MOUNTING
The resistor is suitable for processing on cutting and bending machines. Ensure that the temperature rise of the
resistor body does not affect nearby components or materials by conducted or convected heat. Figure 26 shows
the hot-spot temperature rise of the resistor body as a function of dissipated power. Figures 27 to 34 show the lead length
as a function of dissipated power and temperature rise.

TESTS AND REQUIREMENTS
Temperature: 15 °C to 35 °C
Essentially all tests are carried out in accordance with the
schedule of “IEC publications 60115-1 and 60115-4”,
category 40/200/56 (rated temperature range −40 °C to
+200 °C; damp heat, long term, 56 days). The testing also
covers the requirements specified by EIA and EIAJ.
Relative humidity: 45% to 75%
Air pressure: 86 kPa to 106 kPa
(860 mbar to 1060 mbar).
In Table 4 the tests and requirements are listed with
reference to the relevant clauses of
“IEC publications 60115-1, 115-4 and 68” ; 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, “Recommended basic climatic and
mechanical robustness testing procedure for electronic
components” and under standard atmospheric conditions
according to “IEC 60068-1”, subclause 5.3.
All soldering tests are performed with mildly activated flux.
