Maximum DC current occurs when either the inductance falls to 75% of its nominal value or when its temperature rise reaches 40°C,
whichever is sooner.
RoHS COMPLIANCE INFORMATION
This series is compatible with RoHS soldering systems. Surface mount products can withstand
a peak temperature of 280°C. The pin termination finish on this product series is pure tin dip. All
types are backward compatible with Sn/Pb soldering systems.
