Signal Transformers

Würth Elektronik Signal Transformers include LAN, analog, and data communication transformers. These transformers were developed for power over ethernet (PoE), power line communications (PLC), position sensors, DSL, and Internet of Things (IoT). Würth Elektronik Signal Transformers are ideal for routers, switches, building automation, lighting controls, and ultrasonic distance sensors.
