Operating Temperature Range –55°C to +125°C

Current Rating at 90°C Ambient 35°C Rise

Maximum Power Dissipation at 90°C 0.278 W

Inductance Measured at 1V with no DC current

Incremental Current The current at which the inductance

will be decreased by a maximum of 5% from its initial zero
DC value.

Marking API/SMD; inductance with units and tolerance
followed by an SP; date code (YYWWL). Note: An R before
the date code indicates a RoHS component.
