power chip inductors - 1008ps series document 219-1 specifications subject to change without notice. document 219-1 revised 10/4/02 coilcraft?s 1008ps series is designed to be an economi- cal alternative to larger and more costly shielded power inductors. only 2.74 mm high, they are ideal for applications requiring magnetic shielding, the smallest possible size and lowest cost. typical uses include notebook comput- ers, pc cards, wireless communication and handheld devices. the specially designed ferrite cover provides magnetic shielding and the best possible surface for pick and place handling. coilcraft designer?s kit c141 contains six samples each of the standard parts shown. to order, contact coilcraft or visit http://order.coilcraft.com . 2 dcr 4 2 srf 5 part 2 l 20% 2 2 q min 3 max typ 2 i sat 6 2 i rms 7 1 number 1 (h) @ 1 mhz (ohms) (mhz) (a) (a) 1008ps-102m_ 1.0 35 0.05 344 3.0 2.00 1008ps-152m_ 1.5 35 0.06 260 2.8 2.00 1008ps-182m_ 1.8 35 0.09 225 2.1 1.90 1008ps-272m_ 2.7 38 0.14 185 1.3 1.60 1008ps-392m_ 3.9 38 0.26 175 1.2 1.20 1008ps-472m_ 4.7 38 0.35 160 1.0 1.10 1008ps-562m_ 5.6 38 0.36 150 1.0 0.90 1008ps-682m_ 6.8 38 0.58 120 0.84 0.80 1008ps-103m_ 10 38 0.92 105 0.78 0.72 1008ps-153m_ 15 38 1.15 35 0.70 0.60 1008ps-223m_ 22 40 1.40 26 0.65 0.55 1008ps-333m_ 33 45 1.61 20 0.51 0.50 1008ps-393m_ 39 45 1.85 16 0.45 0.47 1008ps-473m_ 47 45 2.5 19 0.40 0.42 1008ps-683m_ 68 45 3.8 12 0.31 0.32 1008ps-823m_ 82 45 4.3 9.0 0.30 0.30 1008ps-104m_ 100 45 5.8 7.0 0.30 0.30 1008ps-124m_ 120 50 6.3 7.0 0.25 0.28 1008ps-154m_ 150 50 7.5 5.8 0.22 0.26 1008ps-224m_ 220 55 10.0 10.0 0.22 0.21 1008ps-334m_ 330 55 11.5 3.8 0.20 0.19 1008ps-474m_ 470 55 16.3 3.1 0.16 0.18 1008ps-564m_ 560 55 18.1 2.8 0.13 0.15 1008ps-684m_ 680 55 24.0 2.5 0.12 0.14 1008ps-824m_ 820 45 26.0 1.5 0.10 0.12 1008ps-105m_ 1000 45 29.0 2.0 0.10 0.11 1. specify packaging code: 1008ps-105m c packaging: c =7 machine-ready reel. eia-481 embossed plastic tape (750 parts per full reel). b = less than full reel. in tape, but not machine ready. to have a leader and trailer added ($25 charge), use code letter c instead. d =13 machine-ready reel. eia-481 embossed plastic tape (2500 parts per full reel). 2. inductance measured at 100 khz, 0.1 vrms, using coilcraft smd-a fixture in agilent/hp 4263b impedance analyzer. 3. q measured on agilent/hp 4291 with agilent/hp 16193 test fixture. 4. dcr measured on micro-ohmmeter and coilcraft ccf840 test fixture. 5. srf measured using agilent/hp 8753d network analyzer and coilcraft smd-d test fixture. 6. dc current at which the inductance drops 10% (typ) from its value without current. 7. average current for a 40c rise above 25c ambient. 8. operating temperature range -40c to +85c. 9. electrical specifications at 25c. see qualification standards section for environmental and test data.
