Notes
  1. When ordering, please specify packaging code: e.g. FL2810-1LD
  2. Inductance is measured across both halves of the primary.
  3. Vrms = continuous voltage.
  4. Vinst = instantaneous voltage at startup.
  5. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. Windings to core isolation is 1500 Vrms for all parts. Isolation is tested for one minute.
    For Schematic B, primary is not isolated from the secondary.

Packaging:

  • D = 13″ machine ready reel.
    EIA-481 embossed plastic tape. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
    Package 1: 400 parts per full reel.
    Package 4: 800 parts per full reel.
    Package 5: 1000 parts per full reel.
  • 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.

Soldering/Washing

Resistance to soldering heat:
Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
Refer to Soldering Coilcraft Components before soldering.
PCB Washing:
Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info
