Power Metal Film Resistors

MARKING

The nominal resistance and tolerance are marked on the

resistor using four coloured bands in accordance with IEC

publication 60062, “Colour codes for fixed resistors”.

OUTLINES

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.

Note

1. Recommended minimum value.

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”.
