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.
ABSOLUTE MAXIMUM RATINGS
1 Specifications typical at T
A
=25°C
2 The maximum DC current is the value at which the inductance falls to 75% of its nominal value or until its tempera-
ture rise reaches 40°C, whichever is sooner.
3 For tape and reel packaging details refer to datasheet NDC AN002.
Operating free air temperature range –40°C to 85°C
Storage temperature range –40°C to 125°C
