? coilcraft, inc. 2005 specifications subject to change without notice. please check our website for latest information. dw3316 coupled inductors for xdsl document 232 document 232 revised 01/05/05 the dw3316 features a unique dual winding configura- tion that provides two balanced coupled inductors in a single package. this increases circuit efficiency, re- duces component count and conserves valuable board space. interwinding isolation for this part is 500 vrms. the design is optimized for various xdsl filtering appli- cations and its small size and low profile make it particu- larly attractive for central office equipment. other applications include use as a common mode choke or a 1:1 transformer. in addition to the standard inductance values shown, coilcraft can customize these inductors to help achieve specific corner frequencies. inductance 1 dcr srf 2 20% max typ i sat 3 part number (mh) (ohms) (mhz) (ma) dw3316-155 1.5 10.8 1.70 300 dw3316-275 2.7 18.0 1.25 230 dw3316-335 3.3 20.0 1.10 180 DW3316-395 3.9 23.0 0.968 160 dw3316-475 4.7 26.0 0.850 160 dw3316-685 6.8 42.0 0.690 150 1. inductance is per winding, tested at 10 khz, 0.1 vrms, 0 adc. 2. srf is measured using an agilent/hp 8753d network analyzer. 3. dc current at which the inductance drops 10% (typ) from its value without current. 4. operating temperature range -40c to +85c. 5. electrical specifications at 25c. see qualification standards section for environmental and test data. 4 1 3 2 0.330 8,38 dia 0.515 13,08 max 0.200 5,08 max 0.280 7,10 0.115 2,92 0.110 2,79 0.100 2,54 0.100 2,54 0.490 12,45 0.290 7,37 0.185 4,70 color dot 1 2 3 4 0.400 10,16 max recommended land pattern schematic terminations: nickel/gold over phos bronze tape and reel: 250/7 reel; 750/13 reel 24 mm tape width for packaging data see tape and reel specifications section.
