Notes
  1. For optional cover add "C" to part number just before the "L": e.g. DLF 8500CL. Not available on 3500, 4000 and 4500 parts.
  2. Frequency at which the differential mode attenuation equals 3 dB.
  3. Inductance is per winding.
  4. DCR is per winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  5. Interwinding isolation measured for one minute.

Termination:

  • Tin-silver over tin over phos bronze.
