DESCRIPTION
The 800 Series of inductors are particularly
suited to use with a wide variety of switching
regulators. Offering high current handling with a
low mounting height, the devices are ideal where
space is at a premium.

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.

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.
