% OF RATED CURRENT
Current Rating
Based on continuous operation
at room temperature. Derating is required at elevated
ambient temperatures in accordance with the derat-
ing 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.
