Chilisin has released the common mode chokes series CUW43 aimed at applications in automotive electronics. This application focus translates into a halogen-free implementation, and the products meet RoHS and REACH guidelines, noted the company.


In addition, the devices are tested according to automotive quality standard AEC-Q200. Since recently, they can be ordered through Blume Elektronik Distribution GmbH (Salzdethfurth, Germany).

The dimensioning of the CUW43 common mode chokes is based on the requirements for CAN and FlexRay data bus systems. The chokes can be soldered easily with lead-free solders. Presently, the product family is available with four different values from 11μH to 100μH. The chokes excel through their high noise suppression. They are specified to operate in the temperature range from -40°C to 125°C. Customer specific modifications upon request.
