test duration in the course of final inspection (100% end of line testing). This test may be repeated
once as an incoming goods inspection test.
7.3
The rated current l
the nominal operating conditions.
For components with 1, 2 or 3 lines, the rated current is specified for simultaneous flow of a current
of this value through all lines.
During ac operation, higher thermal loads may be caused due to waveforms which deviate from a
pure sine wave. Where necessary, such cases must be taken into consideration.
7.4
The rated current may be exceeded briefly. Details on permissible currents and load duration can
be obtained upon request.
7.5
Saturation effects (e.g in the ferrite cores used) may occur when high-energy pulses are applied to
the components and these may lead to impaired interference suppression. The maximum permis-
sible voltage-time integral area is used to characterize the pulse handling capability of chokes. For
standard components a range from 1 to 10 mVs can be assumed. More specific data can be ob-
tained upon request.
7.6
At ambient temperatures above the operating temperature stated in the data sheet, the operating
current must be reduced according to the derating curve.
