combination line filter chokes document 144-1 document 144-1 revised 02/03/16 this series of chokes is intended for use in ac line flters for switching power supplies. they combine common and differential mode fltering in a single component. by using these parts, designers can eliminate two extra fl - ter chokes compared to a standard common mode choke. the unique combination of special windings and materials provides much better fltering performance than either a common mode choke or a single winding inductor alone. the differential fltering frequency response is designed to provide fltering at higher frequencies while still allow - ing the ac line power to pass through without loss. this characteristic is demonstrated in the differential mode attenuation curves. common mode common mode differential mode part impedance inductance inductance irms 1 dcr max 2 isolation 3 number max (kohms) typ (mh) typ (h) (a) (ohms) (vrms) P3717-AL 597 @ 0.18 mhz 25.0 1000 3.0 0.30 1500 q4007-al 277 @ 0.66 mhz 4.5 150 5.0 0.06 1500 q4018-al 43.3 @ 1.2 mhz 1.5 35 10 0.02 1500 1. current that causes a 40c temperature rise from 25c ambient. this information is for reference only and does not represent absolute maxi - mum ratings. 2. dcr is specifed per winding. 3. isolation (hipot) measured for one minute. 4. electrical specifcations at 25c. common and differential mode core material ferrite terminations rohs compliant tin-silver over tin over copper. weight 100 C 113 g ambient temperature C40c to +85c storage temperature component: C40c to +85c. tray packaging: C40c to +80c moisture sensitivity level (msl) 1 (unlimited foor life at <30c / 85% relative humidity) failures in time (fit) / mean time between failures (mtbf) 38 per billion hours / 26,315,789 hours, calculated per telcordia sr-332 packaging 30 per tray (after 5/09); 16 per tray (prior to 6/09) pcb washing tested to mil-std-202 method 215 plus an additional aqueous wash. see doc787_pcb_washing.pdf . us uk t aiwan china singapore +1-847-639-6400 sales@coilcraft.com +44-1236-730595 sales@coilcraft-eur ope.com +886-2-2264 3646 sales@coilcraft.com.tw +86-21-6218 8074 sales@coilcraft.com.cn + 65-6484 8412 sales@coilcraft.com.sg ? coilcraft inc. 2016 this pr oduct may not be used in medical or high risk applications without prior coilcraft appr oval. specification subject to change without notice. please check web site for latest infor mation.
