? coilcraft, inc. 2005 specifications subject to change without notice. please check our website for latest information. power inductors - dc1012 series document 147 document 147 revised 04/25/05 these power inductors are especially effective as dc-dc converter boost or buck inductors and as output ripple filter chokes in all types of downsized switching power supplies. they are ideal for applications requiring small size, cost effective power inductors. the vertical style helps re- duce power supply size by saving crucial printed circuit board area. the large inductance available per size makes these parts ideal for all sorts of energy storage, smoothing, and emi reduction applications. the coilcraft dc1012 series includes a wide range of eia standard inductance values. custom versions are also available. coilcraft designer?s kit p210 contains three samples of all the standard parts shown. to order, contact coilcraft or visit http://order.coilcraft.com . weight: 2.1 ? 3.0 g dcr srf part inductance 1 max typ i sat 2 i rms 3 number 10% (h) (ohms) (mhz) (a) (a) dc1012-103 10 0.026 35 3.5 3.5 dc1012-123 12 0.030 25 3.2 3.2 dc1012-153 15 0.035 18 3.0 3.0 dc1012-183 18 0.038 15 2.8 2.8 dc1012-223 22 0.046 13 2.5 2.5 dc1012-273 27 0.070 12 2.5 2.2 dc1012-333 33 0.080 11 2.2 2.0 DC1012-393 39 0.088 10 2.1 1.8 dc1012-473 47 0.100 9.0 1.8 1.6 dc1012-563 56 0.15 8.0 1.6 1.4 dc1012-683 68 0.17 7.0 1.4 1.2 dc1012-823 82 0.20 6.0 1.2 1.2 dc1012-104 100 0.22 5.5 1.2 1.2 dc1012-124 120 0.29 5.0 1.2 1.0 dc1012-154 150 0.34 4.5 1.0 0.9 dc1012-184 180 0.38 4.0 0.9 0.8 dc1012-224 220 0.44 3.5 0.8 0.7 dc1012-274 270 0.62 3.25 0.7 0.7 dc1012-334 330 0.70 3.0 0.7 0.6 r4793-a 4 18 5 0.035 15 4.9 4.9 1. tested at 100 khz, 0.1 vrms, 0 adc. 2. dc current at which inductance drops 10% (typ) from its value without current. 3. average current for a 40c rise above 25c ambient. 4. p4793-a not included in designer?s kit p210. 5. operating temperature range -40c to +85c. 6. electrical specifications at 25c.
