RoHS-konform
We will continue to manufacture and support the WB series indefinitely. However, for new designs, consider the SWB, which is a drop-in replacement as an alternative to this series.
  • Surface mount and through hole versions
  • 500 V interwinding isolation, 1/4 Watt RF input power
  • 250 mA max current rating.
  • For a smaller package size, see our PWB Series

Hinweise
  1. When ordering surface mount parts, please specify a packaging code: e.g. WB3040-SMLD
    Through-hole parts are packaged 70 per tube and do not require a packaging code when ordering.
  2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc
  3. Impedance ratio is for the full primary winding to the full secondary winding.

Anschlüsse:

  • RoHS-compliant. Matte tin over nickel over phos bronze. Other terminations available at additional cost.

Verpackung:

  • D = 13″ machine ready reel. EIA-481 embossed plastic tape (500 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
