Document 143-1 Standard Series High L Series Common Mode Line Chokes Coilcraft’s Toroid Style common mode chokes are designed for optimum performance. Their single layer windings provide for the highest common mode impedance over the widest frequency range. Spacers, specially designed by Coilcraft, provide 3 mm creepage and clearance spacings for compatibility with UL, CSA and IEC safety specifications. These common mode line chokes come in two series: Standard and High Inductance. Both are particularly suitable for switching power supplies operating in the 100-300 kHz range of switching frequencies. Coilcraft Designer’s Kit P402 contains samples of eight standard EE and toroidal common mode line chokes. To order, please contact Coilcraft or purchase on-line at http://order.coilcraft.com.

Operating temperature range –40°C to +85°C. Electrical specifications at 25°C. Parts in bold type are included in Coilcraft Designer’s Kit P402. Shown here are typical common mode frequency plots of each part number. The plots indicate the relative performance of each part over the frequency range of most interest for designers of equipment that must meet FCC and VDE noise regulations. It is important to note 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 unimpeded by the common mode impedance. The insertion loss for differential signals is shown in the lower graph. These data were taken in a 50 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.
