smt power inductors - dh3316 series these power inductors feature a small footprint, magnetic shielding and very high efficiency, making them ideal for high performance dc-dc converter applications. like all coilcraft surface mount power inductors, they are designed with a flat top for reliable pick and place operations. the terminations wrap around the end of the base, ensuring a sound solder fillet and simplifying inspection. saturation current ratings up to 10 a and rms current ratings as high as 6 a are available. very low dc resistance keeps power losses to a minimum. in addition to the standard values shown here, dh3316 inductors in custom values are also available. for free evaluation samples or to order, contact coilcraft or visit www.coilcraft.com . l 20% 1 dcr max srf typ 2 i sat 3 i rms 4 part number (h) (ohms) (mhz) (a) (a) dh3316p-102 1.0 0.016 290 10.0 6.0 dh3316p-222 2.2 0.020 150 6.7 4.1 dh3316p-332 3.3 0.025 75 5.7 3.7 dh3316p-472 4.7 0.030 55 4.6 3.2 DH3316P-682 6.8 0.048 42 3.6 2.6 dh3316p-103 10 0.065 37 3.2 2.2 dh3316p-153 15 0.084 27 2.6 1.8 dh3316p-223 22 0.126 24 2.2 1.6 dh3316p-333 33 0.198 17 1.7 1.2 dh3316p-473 47 0.295 12 1.5 1.0 dh3316p-683 68 0.415 11 1.1 0.90 dh3316p-104 100 0.620 9 1.0 0.60 dh3316p-154 150 0.970 7 0.8 0.51 dh3316p-224 220 1.270 6 0.65 0.44 dh3316p-334 330 1.850 5 0.50 0.38 dh3316p-684 680 4.400 3 0.35 0.23 dh3316p-105 1000 5.850 2.5 0.27 0.22 1. inductance tested at 0.1 vrms, 100 khz, 0 adc. 2. srf measured using agilent/hp 8753d network analyzer. 3. dc current at which the inductance drops 10% (typ) from its value without current. 4. average current for a 40c rise above 25c ambient. 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. document 303-1 specifications subject to change without notice. document 303-1 revised 01/27/05 weight: 860 ? 980 mg terminations: nickel/gold over phos bronze tape and reel: 1000/13 reel 24 mm tape width for packaging data see tape and reel specifications section.
