Common-mode inductors choke off conductive EMI
By Bill Schweber -- EDN, 9/8/2005
New through-hole inductors from J W Miller Magnetics put high
inductance into a small footprint, most commonly for use as part of a line
filter that suppresses conductive EMI from switched-mode power supplies. Devices
in the Model 7400 family measure 19×21 mm; inductance ranges from 0.6 to 45 mH,
and dc resistance is 0.025 to 2.68Ω. Operating temperature is –55 to +105°C, for
these approximately $1 units.
