These parts are not recommended for new designs. They have been replaced by parts in the
XFL3012 series, which are the same size, have very similar electrical characteristics and have the same recommended land pattern. The RA6854-AE, RA6855-AE, RA6856-AE and RA6831-AE are available only to existing customers (with previous order history). If you are a current customer, please click here for more information.

注释
  1. When ordering, please specify packaging codes: e.g.RA6831-AEC
  2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
  3. DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using an Agilent/HP 4395A or equivalent.
  5. Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
  6. Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

端子:

  • RoHS compliant tin-silver-copper (96.5/3/0.5) over tin over nickel over silver-platinum. Other terminations available at additional cost.

包装:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (2000 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 C instead.
  • D = 13" machine-ready reel
    EIA-481 embossed plastic tape (7500 parts per full reel). Factory order only, not stocked.
