Rated current:The rated current is the smaller of the values given based on the rate of inductance change (30% decrease from the initial value) or the

temperature rise (temperature rise of 40°C caused by the heat generated by the product itself).

∗2

Inductance is at 1/2 Idc1 power distribution. The L vaule at 0A is higher than the guaranteed performance.

• Operating temperature range: –40 to +105°C (Including self-temperature rise)

• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific

bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.

• All specifications are subject to change without notice.
