HC7 Series HIGH CURRENT 7 Power Inductors Description RoHS 2002/95/EC • 155°C 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 0.22 uH to 4.81 uH • Current range from 35.8 to 9.8 Amps • Frequency range 1kHz to 500kHz Applications • Next generation microprocessors • High current DC-DC converters • VRM, multi-phase buck regulator • PC, Workstations, Routers • Telecom soft switches, Base Stations Environmental Data • Storage temperature range: -40°C to +155°C • Operating ambient temperature range: -40°C to +155°C (range is application specific) • Solder reflow temperature: +260°C max. for 10 seconds max. Part Number HC7-R20-R HC7-R47-R HC7-1R0-R HC7-1R5-R HC7-2R2-R HC7-3R9-R HC7-4R7-R 1) Test Parameters: 100KHz, 1.0Vrms 2) Irms Amperes for approximately ∆T of 40°C above 85°C ambient 3) Isat Amperes Peak for approximately 15% rolloff (@20°C) 4) Isat Amperes Peak 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% V-uS rating is equivalent to a ripple current Ip-p of 20% of Isat (30% rolloff option). It is recommended that the temperature of the part not exceed 155°C under worst case operating conditions verified in the end application.
