DESCRIPTION
The 2400 series is a range of bobbin-wound,
surface-mount inductors designed for use in
switching power supply, and power line filter
circuits. The parts are suitable for any application
requiring a high saturation current in a miniature
surface-mount footprint. Where EMI is a critical
factor, the devices are available with an integral
ferrite EMI shield.

ABSOLUTE MAXIMUM RATINGS
Operating free air temperature range
-40°C to 85°C
Storage temperature range
-40°C to 125°C
Specifications typical at TA = 25°C
1 The maximum DC current is the value at which the inductance falls to 80% 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 with a peak reflow solder temperature of
250ºC. The pin termination finish on this product series is reflowed SAC305. The series is backward compatible with Sn/Pb soldering systems.
