Product Description

The WE-STST series of ultra-compact signal transformers for LAN interfaces has been released. The part size is 4.7 x 3.22mm and the height is only 2.9mm. Supports up to 10G Base-T applications.

The "WE-STST" series is completely machine-manufactured, achieving a significant reduction in size compared to conventional plastic case and toroidal transformer configurations while ensuring high reliability.

The product is available in 4 versions.

• 74930000: Suitable for 10/100/1000 Base-T LAN applications.

74930100: Features excellent signal integrity at high frequencies and is suitable for 10G Base-T applications.

749302010: Suitable for short-range ultrasonic sensor applications.

749302011: Suitable for long range ultrasonic sensor applications.
