Industrial Single Pair Ethernet (SPE) Inductors TDK Industrial Single Pair Ethernet (SPE) Inductors are based on the IEEE 802.3cg standard for 10BASE-T1L. These SPE inductors offer all the inductors that are needed to implement industrial SPE with and without power transmission using a Power over Data Line (PoDL). The suppression of asymmetrical interference is significant in achieving interference-free data traffic. With PoDL, it is possible to connect actuators and sensors with just one pair of wires and realize both data and power transmission via this line. These inductors are RoHS compliant and designed for a -40°C to +125°C operating temperature range.
