HC9 Series High Current 9 Power Inductors Description • 155°C maximum total operating temperature • Surface mount inductors designed for higher speed switch mode applications requiring lower inductance, low voltage and high current 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 µH 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% µH 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) Amps (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 1) Test Parameters: 100kHz, 1.0Vrms 2) Irms amps for approximately ∆T of 40°C without core loss. Derating is necessary for AC currents. Pad 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 155°C under worst case conditions verified in the end application. 3) Peak current for approximately 20% rolloff @20°C 4) Peak current for approximately 30% rolloff @20°C 5) Applied Volt-Time product (V-µS) across the inductor. This value represents the applied V-µS at operating frequency necessary to generate additional core loss which contributes to the 40°C temperature rise. De-rating of the Irms is required to prevent excessive temperature rise. The 100% VµS rating is equivalent to a ripple current Ip-p of 20% of Isat (30% rolloff option). 1207 BU-SB07346 Page 1 of 3 • Design utilizes high temperature powder iron material with a non-organic binder to eliminate thermal aging • Inductance Range from 0.2µH to 47.0µH • Current Range from 3.65 amps to 95.0 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: -40°C to +155°C • Operating temperature range: -40°C to +155°C (range is application specific) • Solder reflow temperature: +260°C max for 10 seconds maximum Packaging • Supplied in tape and reel packaging, 450 parts per reel Isat(3) Amps 20% rolloff 65 40 28 22 18 15 13.2 11.4 8.6 6.0 4.8 3.9 Isat(4) Amps 30% rolloff 95 57 41 32 26 22 19.1 15.1 12.5 8.7 7.0 5.7 DCR (mΩ) max. @ 20°C 0.50 0.88 1.87 2.27 3.37 4.87 5.90 9.40 14.0 25.7 48.8 72.3 Part number definition: First 3 characters = Product code and size.
