DESCRIPTION
The 1200RS Series of inductors is suitable for
power line fi ltering in low to medium current
applications such as switching power supply
circuits. The integral ferrite shield makes these
devices ideal for protecting circuits susceptible
to EMI.
For lower current versions with the same
footprint see our 1200LRS Series.

Storage temperature range -40°C to 125°C
SOLDERING INFORMATION2
Peak wave solder temperature 260˚C for 10 seconds
Pin fi nish Matte tin
All specifi cations typical at TA=25°C
1 Maximum DC current occurs when either the inductance falls to 75% of its nominal value or when its temperature rise reaches 40°C,
whichever is sooner.
