Inductance Range: 0.56~4.7µH

• 11.7×10.8mm square and 5.5mm Max. height.

• Magnetically shielded, low DC resistance.

• Suitable for large current

• The use of magnetic metal alloy powder ensure capability

• Low audible core noise.

• Ideal for DC-DC converter applications in hand held

• RoHS compliant.

(1) Inductance is measured with a LCR meter 4284A (Agilent

(2) DC resistance is measured with 34420A (Agilent Technologies) or

(3) Inductance Decrease Current based upon 20% inductance reduction

(4) Temperature Rise Current based upon 40°C temperature rise.

(5) Absolute maximum voltage 30V
