| HC9 Series HIGH CURRENT 9 Power Inductors Description RoHS 2002/95/EC * 155C maximum total temperature operation * Surface mount inductors designed for higher speed switch mode applications requiring lower inductance, low voltage and high current * Design utilizes high temperature powder iron material with a non-organic binder to eliminate thermal aging * Inductance Range from 0.2 uH to 47.0 uH * Current Range from 95.0 Amps to 3.65 Amps * Frequency Range 1kHz to 500kHz Applications * Next generation processors * High current DC-DC converters * VRM, multi-phase buck regulator * PC, Workstations, Routers, Servers Environmental Data * Storage temperature range: -40C to +155C * Operating temperature range: -40C to +155C (range is application specific) * Solder reflow temperature: +260C max for 10 seconds maximum Part Number HC9-R20-R HC9-R47-R HC9-1R0-R HC9-1R5-R HC9-2R2-R HC9-3R3-R HC9-4R3-R HC9-6R8-R HC9-100-R HC9-220-R HC9-330-R HC9-470-R Rated Inductance H 0.20 0.47 1.0 1.5 2.2 3.3 4.3 6.8 10.0 22.0 33.0 47.0 OCL (1) nominal +/-15% H 0.218 0.544 1.04 1.70 2.53 3.52 4.67 7.45 10.9 22.4 34.5 49.2 Irms (2) Amperes (Typ.) 46.7 33.7 23.7 21.0 17.2 14.3 13.0 10.3 8.50 6.30 4.42 3.65 Packaging * Supplied in tape and reel packaging, 450 parts per reel Isat (3) Amperes 20% rolloff 65 40 28 22 18 15 13.2 11.4 8.6 6.0 4.8 3.9 Isat (4) Amperes 30% rolloff 95 57 41 32 26 22 19.1 15.1 12.5 8.7 7.0 5.7 DCR (m) max. @ 20C 0.50 0.88 1.87 2.27 3.37 4.87 5.90 9.40 14.0 25.7 48.8 72.3 Volts (5) Sec (VS) 2.87 4.78 6.70 8.46 10.4 12.4 14.4 18.1 22.0 31.5 37.3 44.8 1) Test Parameters: 100KHz, 1.0Vrms 2) Irms Amperes for approximately T of 40C without core loss. De-rating is necessary for AC currents. PCB layout, trace thickness and width, airflow, and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 155C under worst case conditions verified in the end application. 3) Peak current for approximately 20% rolloff @20C 4) Peak current for approximately 30% rolloff @20C 5) Applied Volt-Time product (V-S) across the inductor. This value represents the applied V-S at operating frequency necessary to generate additional core loss which contributes to the 40C temperature rise. De-rating of the Irms is required to prevent excessive temperature rise. The 100% V-uS rating is equivalent to a ripple current Ip-p of 20% of Isat (30% rolloff option).
