MARKING

The nominal resistance and tolerance are marked on the

resistor using four or five colored bands in accordance with

IEC 60062, marking codes for resistors and capacitors.

Yellow and grey are used instead of gold and silver because

metal particles in the lacquer could affect high-voltage

properties.

OUTLINES

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 60294).

FUNCTIONAL PERFORMANCE

PRODUCT CHARACTERIZATION

Standard values of nominal resistance are taken from the E96/E24/E12 series for resistors with a tolerance of ± 1 %, 5 %, or

10 %. The values of the E96/E24/E12 series are in accordance with IEC 60063.

Notes

• The maximum permissible hot-spot temperature is 155 °C
