Product Description
The 74942401 LAN Transformer is a high-performance signal transformer specifically designed for Battery Management Systems (BMS). Featuring surface-mount (SMT) design, it integrates a common-mode choke to effectively filter noise and provide galvanic isolation, ensuring safe and reliable operation in high-voltage environments.
With an outstanding isolation strength of 6400 VDC for 1 minute and a maximum operating voltage of 1500 VDC, the 74942401 is ideal for electric vehicles (e-bikes, e-scooters) and energy storage systems (solar storage, UPS). Its compact SMT package offers superior creepage distance while maintaining a small footprint, enhancing system safety and reliability.
