Notes
  1. When ordering, please specify packaging code: e.g. B0310-ALD
  2. Inductance measured between pins 1 and 3 at 250 kHz, 0.1 Vrms, 0 Adc
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. When ordering, please specify packaging code: e.g. MSS6132-103MLC or B0414-ALD
  5. Input Choke: Inductance measured at 100 kHz, 0.1 Vrms.
    Output Choke: Inductance measured at 10.0 kHz, 0.1 Vrms.
  6. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  7. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD-D test fixture. Details
  8. Isolation measured from pin 5 to pins 1, 2, 3, 4.
  9. Input Choke: DC current at which the inductance drops 10% (typ) from its value without current. Details
    Output Choke: DC current at which the inductance drops 12% (typ) from its value without current. Details
  10. Input Choke: Current that causes the specified temperature rise from 25˚C ambient. Details
    Output Choke: Current that causes a 40˚C temperature rise above 25˚C ambient. Details

Termination:

  • RoHS-compliant. 260°C compatible.
    Planar transformers: Matte tin over nickel over brass terminations
    MSS6132: Gold over nickel over phos bronze terminations
    Output choke inductors - Tin-silver over tin over nickel over phos bronze terminations

Packaging:

  • C = 7" machine-ready reel
    EIA RS-481 clear plastic tape (350 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • D = 13" machine-ready reel
    EIA RS-481 clear plastic tape (Transformer: 250 parts per full reel, Input Choke Inductor: 350 parts per full reel, Output Choke Inductor: 200 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 C or B to D.

Soldering

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.
