CommonModeLineChokes – EEStyles

• Low cost

• VDE, IEC, UL, CSA compatible

• 3750 VRMS isolation between windings

• UL approved Class 130°C insulation system

available (UL File E83628)

• Industry-standard EE25 size

• Wide range of available inductances and cur-

rent ratings

Coilcraft Designer’s Kit No. P202 contains sam-

ples of 8 standard EE and toroidal common mode

line chokes. To order, please contact Coilcraft.

Coilcraft common mode standard packages in-

corporate several features to help meet the re-

quirements of all major international safety

agencies. These include 2mm thick center

flanges and 3mm creepage and clearance from

all terminations to the core.

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.

Common mode chokes are used to greatly re-

duce AC line conducted interference produced

by switching power supplies. This configuration

produces opposing magnetic fluxes in the core

that serve to cancel inphase noise signals ap-

pearing across the AC line.

The Coilcraft packaging of common mode

chokes allows windings to be balanced within 1%

and features the cost effectiveness of standard

EE core styles.

This mode allows much more filtering capability

in a given core size than would be possible using
