RA7231 Series

Dual Inductor for Class-D output filters

RoHS 준수 AEC-Q flag
Coilcraft's RA7231 Series uncoupled dual inductors provide two back-to-back inductors that operate independently without coupling effects.  This unique design saves space by combining two inductors in a single package. They are perfect for Class-D applications.
  • Designed for low distortion and the best possible sound quality.

  • Shielded package contains both coils.
  • Very low magnetic coupling
  • AEC-Q200 Grade 1 (−40°C to +125°C)

메모
  1. When ordering, please specify packaging code: e.g. RA7231-ALD
  2. Inductance is for each winding, measured at 100 kHz, 1.0 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer. Minimum inductance is 4.5 µH at 11.5 Adc.
  3. DCR is for each winding, measured on a micro-ohmmeter at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using Agilent/HP 8753D network analyzer.
  5. Isat: DC current (typical) at which the inductance drops the specified amount from its value without current.
  6. Irms: Current applied to both windings at the same time that causes the specified temperature rise from 25°C ambient.

종단 처리:

  • RoHS compliant tin-silver (96.5/3.5) over copper.

패키지:

  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape (150 parts per full reel).
  • B = Less than full reel
    In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.
