  • High Current HEW™ Inductor in low-profile compact form
  • Very low DCR
  • True 45-55 Amp handling capability on the wire (refer to Isat characteris- tic when doing your design to see which is more critical)
  • Core Material: Powdered Cores with distributed air gap for soft saturation
  • Operating Temperature -40ºC to +180ºC
  • Terminations: RoHS compliant, typically SAC305 or equivalent
  • Custom design, higher current, different mounting options available ELECTRICAL PARAMETERS @ 25°C Part Number Inductance1 (μH) ±12% DCR2 (mΩ) Isat3 (Amp) Typical Irms4 (Amp) Typical SRF5 (MHz) Typical Capacitance (pF) Typical Weight (g) Typical Nom Max 10% Drop 20% Drop 30% Drop 20ºC Rise 40ºC Rise HWI3422-055A-110H 11.0 1.50 1.90 39 57 75 36 55 23.0 4.3 100HWI3422-055A-7R3H 7.3 71 101 126 26.0 5.1 HWI3422-055A-4R7H 4.7 > 120 > 150 >180 36.0 4.0 HWI3428-047A-200H 20.0 2.10 2.60 30 42 52 31 47 18.0 3.0 130HWI3428-047A-130H 13.0 58 78 100 25.0 3.1 HWI3428-047A-8R8H 8.8 > 86 > 120 > 160 35.0 2.4 HWI3428-047A-240H 24.0 2.20 2.80 29 42 52 31 47 14.0 5.4 135HWI3428-047A-160H 16.0 48 > 60 > 82 22.0 3.3 HWI3428-047A-100H 10.0 > 86 > 120 > 160 25.0 4.1 HWI3432-045A-290H 29.0 2.60 3.40 26 38 48 30 45 16.0 3.9 138HWI3432-045A-190H 19.0 48 69 86 17.0 4.6 HWI3432-045A-120H 12.0 86 > 120 > 160 25.0 3.4 Note: 1. Inductance measured at 100 kHz, 1.0 Vrms, 0 Adc on Agilent/HP 4284A LCR meter or Equivalent 2. DCR measured on GW Instek GOM-802 Microhmmeter or Equivalent. 3. DC Current at 25°C resulting in % drop of inductance from zero current. Isat is the more critical current specification when less than Irms. 4. Current that causes a specificed temperature rise in an inductor from 25°C ambient. This specification is for reference only as the actual Temperature Rise will depends on the type of wires used and the cooling available (convection via airflow, or conduction through mounting to heat sink). The actual Temperature Rise will be much lower as the flat wire has greater surface for heat dissipation under power. 5. SRF measured using Agilent/HP 4395A network analyzer and an Agilent/HP 43961A test fixture.
