Designed for high density, high current/low voltage applications Solder reflow temperature: J-STD-020D compliant Foil technology that adds higher reliability factor over the traditional magnet wire used for higher frequency circuit designs Pb Frequency Range up to 1MHzHC2 Technical Data 4109 Effective October 2015 High current power inductors Product specifications 4 5 Part number DCR ( ) Volt-sec 1 2 3 Part number (Tape and reel) OCL (H) 20% l amps l amps maximum 20C (V-s) rms sat HC2-R47-R HC2-R47TR-R .52 52.9 63.75 .0006 6.87 HC2-R68-R HC2-R68TR-R .63 52.9 50.00 .0006 6.87 HC2-1R0-R HC2-1R0TR-R 1.15 33.0 42.50 .0013 10.31 HC2-2R2-R HC2-2R2TR-R 2.00 24.3 31.90 .0023 13.75 HC2-4R7-R HC2-4R7TR-R 4.55 17.0 21.25 .0046 20.62 HC2-6R0-R HC2-6R0TR-R 6.00 17.0 16.50 .0046 20.62 3. Peak current for approximately 30% rolloff. 1. Open Circuit Inductance Test Parameters: 300kHz, 0.250 Vrms, 0.0 Adc 4. Values 20C 2. DC current for an approximate temperature change of 40C without core loss. Derating is necessary 5. Applied Volt-Time product (V-s) across the inductor. This value represents the applied V-s at for AC currents. PCB layout, trace thickness and width, air-flow and proximity of other heat 300KHz neccessary to generate a core loss equal to 10% of the total losses for 40C temperature rise. generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 125C under worst case operating conditions verified in the end application.
