DESCRIPTION
All speci cations typical at T =25C
The 1200RS Series of inductors is suitable for A
1 Maximum DC current occurs when either the inductance falls to 75% of its nominal value or when its temperature rise reaches 40C,
power line ltering in low to medium current
whichever is sooner.

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.
