1. When ordering, please specify packaging code:
UA8164-BEC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (250 parts 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 C.

2. Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP
4284A LCR meter or equivalent.
3. Capacitance is measured at 100 kHz, 0.1 Vrms.
4. Leakage inductance is for L1 and is measured at 100 kHz, 0.1 Vrms with
L2 shorted.
5. DC current applied to L1, at which the inductance drops 10% from its
value without current.
5. Electrical specifications at 25°C.
