FUNCTIONAL DESCRIPTION

Product characterization

Standard values of nominal resistance are taken from the E24 series for resistors with a tolerance of ±5%.

The values of the E24 series are in accordance with “IEC publication 60063”.

Note

1. The maximum voltage that may be continuously applied to the resistor element, see “IEC publication 60266”.

The maximum permissible hot-spot temperature is 350 °C.

DERATING

The power that the resistor can dissipate depends on the operating temperature; see Fig.1.
