smt power inductors - do3316hc series document 196-1 specifications subject to change without notice. document 196-1 revised 10/15/03 the do3316hc series has been specially designed for high current, low voltage dc-dc converter applications. this simple, rugged design provides current ratings nor- mally available only in much larger packages ? up to 17 arms for a 0.12 h part! with its tinned self-leaded construction, the do3316hc achieves very low dcr values and excellent solderability. in addition to the standard parts shown, custom values are also available. the do3316hc series includes features such as tape and reel packaging and a flat top for pick-and-place handling that are standard in all coilcraft smt power products. coilcraft designer?s kit c126 contains three samples each of the standard parts shown. to order, contact coilcraft or purchase the kit on-line at http://order.coilcraft.com . 1. part number on reel label may have a b suffix to indicate that the reel is not machine ready. 2. inductance tested at 100 khz, 0.1 vrms, 0 adc. 3. srf measured using agilent/hp 8753d network analyzer. 4. dc current at which the inductance drops 10% (typ) from its value without current. 5. average current for a 40c rise above 25c ambient. 6. operating temperature range -40c to +85c. 7. electrical specifications at 25c. see qualification standards section for environmental and test data. 1 dcr srf 3 part l 20% 2 max typ 2 i sat 4 2 i rms 5 number 1 (h) (ohms) (mhz) (a) (a) do3316p-121hc 0.12 0.0015 200 28 17 do3316p-331hc 0.33 0.002 200 20 16 do3316p-681hc 0.68 0.005 200 13 12 do3316p-102hc 1.0 0.006 100 11 10 do3316p-152hc 1.5 0.008 90 9.0 9.0 do3316p-222hc 2.2 0.011 80 7.8 7.4 do3316p-272hc 2.7 0.012 65 7.0 6.6 do3316p-332hc 3.3 0.014 60 6.4 5.9 do3316p-392hc 3.9 0.015 50 5.9 5.3 do3316p-472hc 4.7 0.018 45 5.4 4.8 recommended land pattern 1st significant digit 2nd significant digit multiplier 0.060 1,52 0.160 4,06 0.330 8,38 0.340 8,64 0.390 9,91 max 0.250 6,35 max 0.125 0.010 3,12 0,25 0.520 13,21 0.460 11,68 max max 0.360 9.14 min weight: 0.95 ? 1.25 g tape and reel: 750/13 reel 24 mm tape width for packaging data see tape and reel specifications section.
