Cemented wirewound resistors
AC01/03/04/05/07/10/15/20
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 60266
.
The maximum permissible hot-spot temperature is 350
°
C.
D
ERATING
The power that the resistor can dissipate depends on the operating temperature; see Fig.1.
