1. When ordering, please specify packaging code:
RA6870-ALC
Packaging: C= 7″ machine-ready reel. EIA-481 embossed plastic
tape (2000 parts per full reel). Quantities less thanfull reel available: in tape (not machine ready) orwith leader and trailer ($25 charge).
D= 13″ machine-ready reel. EIA-481 embossed plastic
tape (7500 parts per full reel).
B= Less than full reel. In an effort to simplify ourpart numbering system, Coilcraft is eliminating
the need for multiple packaging codes. Whenordering, simply change the last letter of your partnumber from B to C.
2. Frequency at which the differential mode attenuation equals 3 dB
3. Inductance shown for each winding, measured at 100 MHz using
an Agilent/HP 4286A impedance analyzer and a Coilcraft SMD-A
fixture4. Current that causes a 40°C temperature rise from 25°C ambient.
This information is for reference only and does not represent absolute maximum ratings.
5. DCR is specified per winding.
6. Isolation (hipot) measured for one minute.
7. Electrical specifications at 25°C.
