1812CAN Series

Common Mode Choke

Our 1812CAN Series filters a broad frequency range of common mode noise with 50% lower DCR and higher current handling than other CANbus chokes in the market. They are designed for common mode noise suppression on CAN or CAN FD lines in automotive or general industrial automation applications, and can also be used for FlexRay automotive bus systems.

Inductance values from 11 µH to 100 µH

Notes

When ordering, please specify packaging code: e.g. 1812CAN-104NRC
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.
Equal current when applied to each winding simultaneously that causes a 25°C temperature rise from 125°C ambient. This information is for reference only and does not represent absolute maximum ratings.
DCR is specified per winding, measured 25°C on a Keithley 580 micro-ohmmeter and a Coilcraft CCF 858 fixture. For other operating temperatures, use this DCR at Temperature calculator.
Winding to winding isolation (hipot) tested for one minute.

Termination:

RoHS compliant matte tin over nickel over silverpalladium-glass frit.
