CHARACTERISTICS

Description: SMD (shielded) power inductor

Applications: For power source circuits, low profile type DC to

DC converters, DC to AC inverters etc.

Operating Temperature: -40°C to +125°C

Inductance Tolerance: ±20% & ±30%

Testing: Inductance is tested on an HP4284A at 1.0 kHz, 0.5V

IDC Current: Value obtained when DC current flows and the

initial value of inductance has fallen by 10%

Itemp Current: Value obtained when current flows and the

temperature has risen to 40°C

Packaging: Tape & Reel

Marking: Parts are marked with inductance code

Additional Information: Additional electrical & physical

information available upon request

Samples available. See website for ordering information.
