DESCRIPTION 12LRS226C 22000 0.073 70000
The 1200LRS Series of inductors is suitable for
ABSOLUTE MAXIMUM RATINGS
power line ltering in low to medium current
Operating free air temperature range -40C to +85C
applications such as switching power supply
Storage temperature range -40C to 125C
circuits. The integral ferrite shield makes these
devices ideal for protecting circuits susceptible
2
to EMI. SOLDERING INFORMATION
Peak wave solder temperature 260C for 10 seconds
For higher current versions with the same
Matte tin
footprint see our 1200RS Series. Pin nish
All speci cations typical at T =25C
A
1 Maximum DC current occurs when either the inductance falls to 75% of its nominal value or when its temperature rise reaches 40C,
whichever is sooner.
