Single Pair Ethernet Signal Transformers

Würth Elektronik Single Pair Ethernet (SPE) Signal Transformers feature the super small WE-STST series with transformers that measure only 4.7mm x 3.22mm x 2.9mm (L x W x H). These transformers are manufactured by machine and offer 1.5kV isolation voltage and 350µH open-circuit inductance (OCL) as per IEEE 802.3. The modules have an operating temperature range of -40°C to +105°C. Typical applications for Würth Elektronik WE-STST transformers include Ethernet 10/100/1000 Base-T, Ethernet 2.5/5G and 10G Base-T, SPE, ultrasonic sensors, and G.fast.
