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.

2) 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.
