  1. Parallel DCR = DCR per winding / Series DCR = DCR per winding x 2.
  2. Inductance measured at 25˚C.
  3. Max. current measured at 25˚C, 20% inductance roll-off. Above 85˚C operating temp., max. current is reduced.
  4. Plots of Inductance vs. Current available for all above parts. Contact BH.
  5. T&R available: 400 per 13" reel, 1,200 minimum release. Smaller quantities shipped in JEDEC trays.
  6. Highlighted part numbers are standard products. Others are available as non-standard parts with longer lead times.
  7. RoHS parts designated with “L” (e.g., L10-1007). Are electrically the same as non-RoHS designated with “5” (e.g., 510-1007).
  8. RoHS “L” and non-RoHS “5” Catalog Parts use pins with matte Sn over Ni barrier over brass. Wire/pin solder is SAC or Sn63/Pb37, respectively.
  9. Above parts available with Sn90/Pb10 plated pins on a “custom” part basis. Contact us for details.
