common mode line chokes document 143-1 specifications subject to change without notice. document 143-1 revised 11/06/02 coilcraft?s toroid style common mode chokes are de- signed for optimum performance. their single layer windings provide for the highest common mode imped- ance 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 p202 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. standard series high l series standard series high inductance series 1 2 4 3 schematic 0.12 3,0 1.40 35,6 1.40 35,6 0.900 22,86 max max max 23 12 0.150 3,81 0.03 0,76 4 3 2 1 footprint 0.900 22,86 0.600 15,24 1 2 4 3 schematic 0.12 3,0 1.23 31,2 1.25 31,8 0.625 15,88 max max max 23 12 0.150 3,81 0.03 0,76 43 2 1 footprint 0.400 10,16 0.800 20,32
document 143-2 specifications subject to change without notice. document 143-2 revised 10/17/02 standard series shown here are typical common mode fre- quency plots of each part number. the plots indicate the relative performance of each part over the frequency range of most inter- est 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. differen- tial mode power such as 50/60 hz power line currents or data signals will pass through unimpeded by the common mode imped- ance. the insertion loss for differential sig- nals 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. common mode attenuation* differential mode insertion loss* current leakage interwinding lead part inductance rating inductance srf dcr max isolation diameter number min (amps) max (h) typ (ohms) (volts rms) nom p3213-a 3.5 mh 1.3 62 500 khz 0.150 1250 0.051/1,29 p3214-a 1.7 2.0 32 850 0.065 1250 0.051/1,29 p3215-a 1.0 3.2 22 1.25 mhz 0.036 1250 0.051/1,29 p3216-a 750 h 5.0 19 1.30 0.022 1250 0.051/1,29 p3217-a 425 8.1 10 1.75 0.012 1250 0.040/1,02 p3218-a 275 13.0 8 2.00 0.008 1250 0.051/1,29 1. all parts have #16 awg tinned copper wire leads except p3217-a, which has #18 awg leads. 2. operating temperature range ?40c to +85c. 3. electrical specifications at 25c. 4. parts in bold type are included in coilcraft designer?s kit p202. 0 5 10 15 20 25 30 35 40 45 50 frequency (mhz) attenuation (db) 0.0001 0.001 0.01 0.1 1 10 100 p3218-a p3216-a p3217-a p3215-a p3214-a p3213-a 0 5 10 15 20 attenuation (db) 0.1 1 10 100 1000 frequency (khz) p3213-a p3214-a p3215-a, p3216-a, p3217-a, p3218-a * measured on agilent/hp 3577a network analyzer.
