applications.
Notes :
1)
Pollution class 2, overvoltage category III
2)
Linearity data exclude the electrical offset.
3)
Please refer to derating curves in the technical file to avoid excessive
core heating at high frequency
4)
Please consult characterisation report for more technical details and
application advice.
