Coilcraft Designer’s Kit No. P202 contains samples of
eight standard EE and toroidal common mode line
chokes. To order, contact Coilcraft or purchase on-line at
http://order.coilcraft.com.
Coilcraft common mode standard packages incorporate
several features to help meet the requirements of all major
international safety agencies. These include 2 mm thick
center flanges and 3 mm creepage and clearance from all
terminations to the core.
Common mode chokes are used to reduce AC line con-
ducted interference produced by switching power sup-
plies. This configuration produces opposing magnetic
fluxes in the core that serve to cancel in-phase noise
signals appearing across the AC line.
This mode allows much more filtering capability in a given
core size than would be possible using differential filtering
alone. Use of common mode chokes therefore reduces
component count as well as inductor size.
Combining both common and differential mode chokes
gives the power supply designer the added flexibility
required to adjust the filtering to meet FCC, VDE, and
other requirements as well as optimize the circuit for the
particular noise levels and frequencies produced by each
power supply design.
The Coilcraft packaging of common mode chokes allows
windings to be balanced within 1% and features the cost
effectiveness of standard EE core styles.
