FERRITE CHIP INDUCTORS

L3 SERIES

Derating Curve

For the ferrite chip bead which withstanding current over 1.5A, as the

operating temperature over 85°C, the derating current information is

necessary to consider with. For the detail derating of current, please

refer to the Derated Current vs. Operating Temperature curve.
