RoHS COMPLIANCE INFORMATION
This series is compatible with RoHS soldering systems. A peak wave solder
temperature of 300°C for 0 seconds is permitted. The pin termination finish on
this product series is bright tin. All types are backward compatible with Sn/Pb
soldering systems.

All specifications typical at T
A=25°C
Maximum DC current occurs when either the inductance falls to 90% of its nominal value or when its temperature rise reaches 30°C,
whichever is sooner.
