RA6870-AL

Common Mode Choke

Our RA6870-AL common mode choke was developed for Microchip MOST150 Infotainment applications and is specified for the OS82150 MOST150 Coaxial Transceiver, OS81118 MOST150 INIC and OS81119 MOST150 Dual Port INIC. It eliminates virtually all common mode noise over a wide bandwidth.

Notes

When ordering, please specify packaging code: e.g. RA6870-ALC
Frequency at which the differential mode attenuation equals 3 dB
Inductance is for the primary, measured at 100 MHz.
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.
DCR is specified per winding.
Isolation (hipot) measured for one minute.

Termination:

Matte tin over nickel over silver-palladium-glass frit.

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with 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 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.
