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.
1 Specifications typical at T

=25°C
2 The maximum DC current is the value at which the inductance falls to 80% of its nominal value or until its
temperature rise reaches 40°C, whichever is sooner.
Operating free air temperature range –40°C to 85°C
Storage temperature range –40°C to 125°C
