specifications subject to change without notice. please check our website for latest information. smt power inductors C do1608 series document 177-1 the do1608 series has a footprint of only 0.26 0.175 (6,6 mm 4,5 mm). their high energy storage and very low resistance make them the ideal inductors for dc-dc conversion in notebook computers, pdas, step-up or step-down converters, flash memory programmers, etc. for reliable surface mounting, we?ve designed the do series with a flat top and robust temperature deflection to prevent damage during solder reflow. in addition to the standard versions shown here, custom inductors are available to meet your exact requirements. coilcraft designer?s kit c177 contains three samples each of the parts shown. to order, please contact coilcraft or visit http://order.coilcraft.com . part l 20% 2 dcr max srf typ i sat 3 i rms 4 number 1 (h) (ohms) (mhz) (a) (a) do1608c-102 1.0 0.05 130 2.9 2.9 do1608c-152 1.5 0.06 115 2.6 2.8 do1608c-222 2.2 0.07 90 2.3 2.4 do1608c-332 3.3 0.08 70 2.0 2.0 do1608c-472 4.7 0.09 50 1.5 1.5 do1608c-682 6.8 0.13 45 1.2 1.4 do1608c-103 10 0.16 35 1.1 1.1 do1608c-153 15 0.23 30 0.90 1.2 do1608c-223 22 0.37 20 0.70 0.8 do1608c-333 33 0.51 15 0.58 0.6 do1608c-473 47 0.64 14 0.50 0.5 do1608c-683 68 0.86 11 0.40 0.4 do1608c-104 100 1.27 9 0.31 0.3 do1608c-154 150 2.00 6 0.27 0.25 do1608c-224 220 3.11 5.5 0.22 0.20 do1608c-334 330 3.80 5 0.18 0.16 do1608c-474 470 5.06 4 0.16 0.15 do1608c-684 680 9.20 3 0.14 0.12 do1608c-105 1000 13.8 2 0.10 0.07 1. part number on reel label will have a suffix to indicate packaging: c = machine ready 7 reel, b = partial reel, d = machine-ready 13 reel. 2. tested at 100 khz, 0.1 vrms, 0 adc. 3. dc current at which the inductance drops 10% (typ) from its value without current. 4. average current for 15c temperature rise from 25c. 5. operating temperature range ? 40c to +85c. 6. electrical specifications at 25c. see qualification standards section for environmental and test data. see color coding section for part marking data. xxx 0.260 6,60 max 0.175 4,45 max recommended land pattern 0.160 4,06 0.140 3,56 0.055 1,40 0.270 6,86 0.090 2,29 0.040 1,02 min 0.170 4,32 0.050 1,27 part markings 1st significant digit 2nd significant digit multiplier dash number 0.155 3,94 dia 0.115 2,92 max xxx weight: 128 ? 164 mg terminations: nickel/gold over moly-manganese tape and reel: 750/7 reel; 2500/13 reel 12 mm tape width for packaging data see tape and reel specifications section.
