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
2. Inductance is for the primary, measured at 200 kHz, 0.1 Vrms, 0 Adc.
3. DCR for the primary and the secondary is measured with the windings connected in parallel.
4. Leakage inductance is for the primary and is measured with all secondary windings shorted.
5. Turns ratio is with the primary windings and the secondary windings connected in parallel.
6. Output is with the secondary windings connected in parallel.

7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
