Common Mode Line Chokes
AECStandard SeriesHigh L Series

Coilcraft’s Toroid Style common mode chokes are designed for optimum performance. Their single layer windings provide for the highest common mode impedanceover the widest frequency range.

Q200 +85°C

These common mode line chokes come in two series:
Standard and High Inductance. Both are well suitable forswitching power supplies operating in the 100-300 kHz
range of switching frequencies.
• UL1446 Class B (130°C) Insulation System(UL File E83628)• Creepage and clearance = 3.2 mm• 1250 Vrms, one minute isolation between windings
Coilcraft Designer’s Kit P402 contains samples of eightstandard EE and toroidal common mode line chokes.

Common Mode Attenuation*
05P3218-A

10P3217-A

15Attenuation (dB)Shown here are typical common mode frequency plots of each part number. The plots
indicate the relative performance of each partover the frequency range of most interest for
designers of equipment that must meet FCC
and VDE noise regulations. It is important tonote that only a common mode signal will
be attenuated as shown. Differential mode
power such as 50/60 Hz power line currents
or data signals will pass through unimpededby the common mode impedance. The insertion loss for differential signals is shown in
the lower graph. These data were taken in a50 Ohm system. All parts should be tested
using an appropriate Line Impedance Stabilization Network (LISN) when testing EMI/RFI performance of off-line power converters.
