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.
