D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (3500 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.

2. Inductance is for the primary (L1), measured at 100 kHz, 0.1 Vrms,
0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
3. SRF measured using an Agilent/HP 4191A or equivalent.
4. Volt-time product is calculated as Inductance × Isat.
5. DC current applied to L1, at which the inductance drops 10% from its
value without current.
5. Electrical specifications at 25°C.
