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 tested at 0.25 Vrms, 100 kHz, 0 Adc.
3. DC current at which the inductance drops 30% (typ) from its value
without current.
4. Current that causes a 40°C temperature rise from 25°C ambient.
5. Electrical specifications at 25°C.
