Notes
  1. When ordering, please specify packaging code: e.g. Q4470-CLD
  2. Calculated output power is based on 150 kHz operating frequency. Power rating varies depending on application.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Capacitance measured from full primary to full secondary at 200 kHz.
  5. Volt-time product is for the primary.
  6. 1500 Vrms isolation between windings.

Termination:

  • Tin-silver over tin over nickel over phos bronze.

Packaging:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (Size C: 1000 per full reel; Size D: 500 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.

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.
