Product specification

Standard metal film resistors

SFR16S/25/25H

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”.

Limiting values

Note

1. The maximum voltage that may be continuously applied to the resistor element, see “IEC publication 60115-1”.

The maximum permissible hot-spot temperature is 155

°C.

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