Novosense Launches Fully Domestic Automotive CAN Transceiver Certified to Class III EMC Standards

On June 10, Novosense announced the launch of NCA1043D-Q1, an automotive-grade CAN transceiver chip built on a fully domestic supply chain. The device has unconditionally passed all test items at the highest Class III level under the IEC 62228-3 standard at the European testing agency IBEE/FTZ-Zwickau. These tests cover four key aspects: RF emission, RF immunity, transient immunity, and electrostatic discharge (ESD) immunity. The NCA1043D-Q1 also complies with Volkswagen Group’s VW80121-3 standard (December 2023 edition). Novosense can already provide relevant test reports to support automakers in simplifying system certification processes and accelerating time-to-market. As a core component in vehicle communication networks, the EMC performance of CAN transceivers directly impacts overall system reliability. With the increasing adoption of 800V high-voltage platforms, SiC power devices, and composite-material battery packs, the interference immunity of CAN transceivers has become a critical factor influencing both vehicle development cycles and system stability.
