Features
RoHS compliant.
Low profile (1.5mm max. height) SMD type.
Magnetically shielded, suitable for high density mounting.
Self-leads, suitable for high density mounting.
High energy storage and low DCR.
Provided with embossed carrier tape packing.
Idel for power source circuits, DC-DC converter, DC-AC inverters
inductor applications.
In addition to the standard versions shown here, customized inductors
are available to meet your exact requirements.
Electrical Characteristics:
1. Tolerance of inductance: 30% for 2.2~8.2uH; 20% for 10~22uH.
2. Isat is the DC current which cause the inductance drop 35% typical of its nominal inductance without current.
3. Ir is the DC current which cause the surface temperature of the part increase less than
4.Operating temperature : -20
to 105
(including self-temperature rise).
