TECHNOLOGY
Wire wound resistor AC03 / AC05
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 tinned copper-clad leads are
connected to the caps by welding. The resistor is coated with green silicon cement which 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, method 215” and “IEC 60068-2-45”.
Metal film power resistor PR03
A homogenous film of metal alloy is deposited on a high-grade ceramic core. The leads are welded on this
caps and a helical groove has been cut in the resistive layer. The resistor is coated with red silicon cement
which is non-flammable, will not drip even at high overloads and is resistant to most commonly used
cleaning solvents, providing electrical, mechanical and climatic protection.

MARKING
WIRE WOUND RESISTOR
The resistor is marked with the nominal resistance value, the tolerance on the resistance and the rated
dissipation at T
amb
= 25 ºC.
For values up to 910
Ω,
the R is used as the decimal point.
For values of 1 KΩ and upwards, the letter K is used as the decimal point for the KΩ indication.
Example:
6K8 5%
5W
FILM RESISTOR
The nominal resistance and tolerance are marked on the resistor using four or five colored bands in
accordance with IEC publication 60062 “color code for fixed resistors”.
Standard values of nominal resistance are taken from the E24/E96 series for resistors with a tolerance of
±5% or 1%. The values of the E24/E96 series are in accordance with “IEC publication 60063”.

The subsequent 6 or 7 digits indicate the resistor type and packaging see table 2.
For 5% tolerance the remaining 3 digits indicate the resistance value;
- The first 2 digits indicate the resistance value.
- The last digit indicates the resistance decade in accordance with table 3.
For 1% tolerance the remaining 4 digits indicate the resistance value;
