Current Rating

Based on continuous operation

at room temperature. Derating is required at elevated

ambient temperatures in accordance with the derating

curve.

Operating Temperature Range

–55°C to +125°C

Maximum Power Dissipation at 25°C

2.2 W

Weight Max.

(Grams) 12.0

Incremental Current 1)

Current Level which causes a

maximum of 10% decrease in inductance.

The

Incremental Current at ambient temperatures other than

25°C will be 70% of the adjusted current rating.

Marking

DELEVAN; part number without the tolerance

letter, inductance with units. Note: An R after 3443

indicates a RoHS component.
