DESCRIPTION
The 2300 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.
