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.
