CHARACTERISTICS

Description:

SMD (unshielded) power inductor

Applications:

LCD televisions, PC notebooks, portable

communication equipment, DC/DC converters, etc.

Operating Temperature:

-30°C to +100°C

Inductance Tolerance:

±10%, ±20%

Saturation Current:

This indicates the value of current when the

inductance is 10% lower than it’s initial value at D.C. superposition

or D.C. current.

Temperature Current:

To load current onto the components

under normal ambience, which cause the temp., change as

Δt=40°C

or more lower current.

Testing:

Inductance is tested on an HP4285A at 100 kHz, 0.25V.

Packaging:

Tape & Reel

Marking:

Parts are marked with inductance code

Miscellaneous:

RoHS Compliant.

Additional Information:

Additional electrical & physical

information available upon request.

Samples available. See

website for ordering information.
