A829-1J1T-KM Description

Short technical summary and product information.

The Bel Fuse A829-1J1T-KM is a single-port RJ45 modular connector jack with integrated magnetics designed for 1GBase-T (1000 Base-TX) automotive Ethernet applications. This MagJack ICM (Integrated Connector Module) supports 10/100/1000 Base-TX with AutoMDIX, enabling flexible cable detection and correction.

 

Key mechanical specifications include a right-angle (90°) through-hole orientation, tab direction up, and solder termination. The connector is fully shielded with an EMI finger for enhanced electromagnetic compatibility. It has a height above board of 11.18 mm and features a board guide for secure alignment during assembly. Contacts are finished with 50 microinches of gold plating.

 

The A829-1J1T-KM is designed for an operating temperature range of -40°C to 100°C, making it suitable for harsh automotive environments. It incorporates green and orange-yellow LED indicators for link and activity status. The jack is UL recognized, low halogen, and lead-free wave-solder compatible, meeting RoHS 6/6 requirements.
