WE-SPE Signal Transformers for SPE & PoDL

Würth Elektronik WE-SPE Signal Transformers are designed for use in Single Pair Ethernet (SPE), as well as SPE with Power over Data Lines (SPE+PoDL). These transformers provide reliable, high-performance connectivity in a compact package. The WE-SPE series is offered in both 4- and 8-pin configurations to suit user needs. High quality and reliability are ensured by a test voltage of 2250V (DC) for 1 minute, as well as an operating temperature range of -40°C to +125°C. Additional applications for Würth WE-SPE Signal Transformers include Ethernet communication, automotive, and industrial.
