Common Mode Choke 1812CANbus
Halogen
Free
• Designed for common mode noise suppression on CAN
or CAN FD in automotive or general industrial automation
applications
• Can be used for FlexRay automotive bus system
• 50% lower DCR and higher current handling than other
CANbus chokes in the market
• Filters a broad frequency range of common mode noise
• Low profile 1812 footprint: 4.95 × 3.18 × 3.0 mm

1. When ordering, please specify packaging code:
1812CAN-104NRC
Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic
tape (600 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.
Factory order only, not stocked (2200 parts per full reel).
2. Inductance is per winding, measured at 100 kHz, 0.1 Vrms, 0 Adc using
an Agilent/ HP 4263B LCR meter and a Coilcraft CCF 1113 fixture.
3. DCR is specified per winding, measured at on a Keithley 580 micro-
ohmmeter and a Coilcraft CCF 858 fixture.
4. Winding to winding isolation (hipot) tested for one minute.
5. Current per winding that causes a 25°C rise from +125°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
