In addition to new components from the fields of wireless connectivity, power magnetics, optoelectronics and electromechanics, Würth Elektronik will also be presenting a pioneering concept at embedded world from March 11 to 13: Single Pair Ethernet (SPE) with Power over Data Lines (PoDL). At Stand 2-110 in Hall 2 of the Nuremberg exhibition centre, the manufacturer will be presenting the first reference design for an EMC-compliant 10 Mbit/s Ethernet interface, which enables both data transmission and power supply via a single twisted pair of wires.

“With this reference design, we are demonstrating that we not only develop high-quality components for our customers, but we also take care of their optimal use, offering practical and sustainable solutions. Our new reference design helps to reduce cabling costs in industrial and IoT applications. It also reduces weight and saves costs - cutting copper consumption by 50%,” says Alexander Gerfer, CTO of the Würth Elektronik eiSos Group. “Single-pair Power over Ethernet (SPoE) is a space- and material-saving solution. Thanks to our reference design - which we provide including all the design files - it can now be implemented easily, conveniently, standard-compliant and EMC-safe.”

Würth Elektronik's contribution to the embedded world conference program is also dedicated to this topic: Dr. Heinz Zenkner and Adrian Stirn, EMC specialists at the company, will be giving a workshop entitled “Single Pair Ethernet Design with Power over Data Line with EMC Aspects” on 12 March 2025 from 2 to 5 pm.

Component news

At the trade fair in Nuremberg, Würth Elektronik will be presenting Cordelia-I, one of the first wireless modules to comply with the 2022/30 cyber security regulation in accordance with EN18031-1. In the field of storage inductors, for example, the WE-MXGI series is a product that enables maximum efficiency in switching regulator applications. The company's optoelectronics experts will be presenting the expansion of the WL-ICLED range to include dual-wire ICLEDs. The REDEXPERT ICLED Color Calculator is now also available for these RGB LEDs with integrated circuit (IC). This can be used to automatically generate exact PWM signals to display defined color values. Other new products include USB-C components and additional sizes of the popular WE-CNSW current-compensated data line filters.

Würth Elektronik’s subsidiary IQD will be co-exhibiting at the stand with quartz crystals and oscillators. In addition, the semiconductor manufacturers Analog Devices and onsemi will be guests at the stand as partners to present joint reference designs. Würth Elektronik is also once again taking part in the Students Day, which this time takes place on March 13.
