Wire Wound Common Mode Chokes AMCW-B Series for Automotive CAN BUS
Overview

Wire Wound CMC AMCW-B series with inductance from 11μH -100μH and working temperature from-40~+150℃, can be used to suppress common mode noise in high speed differential signal lines and is widely used for noise suppression in automotive buses such as CAN and FlexRay.

Background

With the automotive industry revolution continues, the application and innovation of automotive electronic technology have greatly promoted the progress of the automotive industry. The number of electronic equipments in the automotive has significantly increased. This trend has enabled the vehicle to be equipped with diversified functions, such as entertainment, office and communications, navigation systems, smart drive, and so on. All ECUs and vehicle-mounted appliances will be gradually loaded onto the automotive network platform to achieve data sharing and intelligent control. Commonly multimedia functions are connected by LIN (Local Interconnect Network) or MOST (Media Guided System Transport) bus, and CAN and FlexRay bus systems are critical to safety systems such as engine control, ABS systems, and airbags. CAN and FlexRay bus systems must be satisfied with the highest electromagnetic compatibility specifications. In order to ensure reliable communication between various control units, Sunlord’s AMCW-B series common mode chokes have been developed to solve the EMI in CANBUS. AMCW-B series common mode choke as a countermeasure against EMC and noise suppression at the interface.
