? coilcraft, inc. 2006 specifications subject to change without notice. please check our website for latest information. data line emi filters C leaded document 149 document 149 revised 01/28/05 these filters are designed to virtually eliminate con- ducted emi in data line applications. they provide exceptional common mode noise reduction from 5 mhz to 300 mhz while passing signal line data frequencies below 200 mhz with minimal attenuation. these low resistance filters feature excellent electrical isolation, environmental stability and low cost. optional covers make them auto insertable. they also meet iec 695-2-2 needle flame test requirements. there are 8, 4, 3 and 2-line versions with dc current capacity of 100 ma (dlf x000 series) or 500 ma (dlf x500 series). coilcraft designer?s kit d303 contains four samples of all values shown plus samples of our ttdlf/ccdlf surface mount filters. to order, contact coilcraft or visit http://order.coilcraft.com . current dcr part max l / winding max isolation number 1 lines (ma) (h) (mohms) (vrms) dlf 8000l 8 100 28 100 300 dlf 8500l 8 500 25 45 300 dlf 4000l 4 100 28 100 300 dlf 4500l 4 500 24 45 300 dlf 3000l 3 100 28 100 300 dlf 3500l 3 500 24 45 300 dlf 2000l 2 100 28 100 300 dlf 2500l 2 500 24 45 300 1. for optional cover add ?c? to part number just before the ?l?: e.g. dlf 8500cl. not available on 3500, 4000 and 4500 parts. 2. operating temperature range -40c to +85c. 3. electrical specifications at 25c. typical response* 8 line 8 line 0.650 16,51 0.100 2,54 0.0315 0,80 pin 1 dia ref 0.700 17,78 0.858 21,79 0.300 7,62 0.455 11,56 0.110 0.010 2,79 0,25 max dia max 0.850 21,59 0.450 11,43 0.350 8,90 0.350 8,90 0.475 12,07 0.450 11,43 0.125 0.020 3,18 0,51 0.0315 0,800 0.430 10,9 2 line and 3 line 4 line 3 line 2 line 30 20 10 0 0.1 1 10 100 1000 frequency (mhz) attenuation (db) re: 50 ohms differential mode common mode dlf x500 com mon m ode dlf x000 16 8 1 7 2 15 6 1 6 1 5 2 4 3 4 3 14 6 3 5 4 13 12 11 10 9 12345678 *measured on hp 8753d network analyzer. terminations: tin-silver over tin weight: dlf2000: 0.74 g; dlf2500: 0.78 g dlf3000: 0.83 g; dlf3500: 0.91 g dlf4000: 0.95 g; dlf4500: 1.09 9 dlf8000: 1.56 g; dlf8000: 2.22 g
