Würth Elektronik Expands its LAN Portfolio with Super Tiny Signal Transformer

Würth Elektronik, a leading European manufacturer of electronic and electromechanical components, is expanding its extensive range of signal transformers. The new series of WE-STST Super Tiny Signal Transformers for LAN interfaces features a maximum component height of just 2.9 mm and can be used up to 1000Base-T applications with at least 350 µH inductance. 

The WE-STST series of signal transformers is ideally suited for all applications in which small component size and outstanding electronic parameters are paramount. In contrast to conventional transformers, which usually consist of toroidal ferrites in plastic housings, the Super Tiny Signal Transformers from Würth Elektronik are manufactured completely by machine. This enables the dimensions to be kept extremely small at only 4.7 × 3.22 × 2.9 mm and yet offers an insulation voltage of 1,500 V / 1 min.

Four versions for different applications

WE-STST is available in four versions for different applications. The first version with 350 µH is suitable for LAN applications with data rates up to 1,000 Mbps. The WE-STST with 120 µH features outstanding signal integrity at high frequencies and is therefore ideal for 10 Gigabit Ethernet applications or for the new Single Pair Ethernet with data rates up to 1,000 Mbps. Further versions with 300 µH or 2,000 µH are suitable for ultrasonic sensor applications and as transformers for the new G.fast standard with a transmission ratio of 1:4.5. 

All four WE-STST versions are now available from stock without a minimum order quantity. Samples may be requested.
