2 W C For rated current of ordinary small power choke coils, please refer to the rated current 1 in the above table.
Rated current 2 is the current for instantaneous flow such as plunging current of DC/DC converter.
In case of usage in the circuit where large current may be semicontinuously applied over 5 minutes with auto recovery circuit, etc.,
please contact our sales section before practical application.
Rated current 1 : Current value to guarantee –30L of nominal inductance
Rated current 2 : Current value to guarantee component temperature within T W40C with current flow.
( It is not the current to guarantee the inductance value.)
