Since 2004, Guangzhou Zhiyuan Electronics has been at the forefront of innovation in the field of isolated CAN transceivers. In that year, they introduced the industry’s first isolated CAN transceiver, the CTM8250, which laid the foundation for a growing market now widely recognized across multiple industries. With years of accumulated expertise and a commitment to continuous improvement, ZLG Zhiyuan Electronics has developed patented CTM isolated CAN transceivers that power countless applications behind the scenes.
In April of this year, the company took another step forward by launching the next generation of its CTM isolated CAN transceiver—the CTMxxKx series. This new product brings significant improvements in three key areas:
1. **Extended Operating Temperature Range and Lifespan**: The CTMxxKx series can operate continuously in an extremely wide temperature range of -40°C to 105°C, making it ideal for harsh environments.
2. **Enhanced Internal Design**: Featuring an isolated DC-DC circuit, the CTM-K series reduces static power consumption by approximately 10mA. More importantly, if there is an abnormality on the CAN interface—such as excessive bus output current or a short circuit—the internal DC-DC automatically limits the output power, preventing further damage and ensuring system stability.
3. **Increased Isolation Voltage**: The isolation voltage has been raised to 3500VDC, effectively blocking transient interference from the bus and significantly improving the reliability of the CAN communication system.

Here are more detailed specifications of the CTMxxKx series:
- Complies with the ISO 11898-2 standard
- Enclosure and potting materials meet the UL94-V0 safety standard
- Low electromagnetic radiation and high immunity to electromagnetic interference
- Excellent performance in both high and low temperature conditions, meeting industrial-grade requirements
- Supports at least 110 nodes on a single network

The CTMxxKx series represents a major leap forward in the development of isolated CAN transceivers, offering enhanced performance, reliability, and adaptability for a wide range of industrial and automotive applications. Whether it's in automation systems, vehicle networks, or smart infrastructure, these transceivers are built to deliver consistent and stable communication under the most challenging conditions.
