Tiny Signal Transformers for LAN Interfaces

November 26, 2019 by Paul Shepard

Würth Elektronik 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 2.9mm and can be used up to 1000Base-T applications with at least 350µH inductance.

The WE-STST series of signal transformers is 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 1,500V / 1 min.

Four versions for different applications

WE-STST is available in four versions for different applications. The first version with 350µH is suitable for LAN applications with data rates up to 1,000Mbps. The WE-STST with 120µH 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 1,000Mbps.

Further versions with 300µH or 2,000µH are suitable for ultrasonic sensor applications and as transformers for the new 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.
