Description of 7490240142 1000base T Transformer :
The 7490240142 is a single-port 1000Base-T transformer engineered to provide reliable and efficient signal isolation for LAN 10/100/1000 Base-T networks. -40 °C to +85 °C wide operating temperature range suitable for commercial and industrial applications. Its surface mount design allows for easy integration into PCBs, making it a versatile choice for various networking devices such as switches, routers, and network interface cards (NICs). Despite not featuring an improved common-mode rejection ratio (CMRR), it maintains high performance and integrity in data transmission. This transformer adheres to IEEE 802.3 standards, providing essential voltage isolation and protecting against high-voltage transients, enhancing the durability and safety of its Ethernet connections.Compliant with most ICs for Ethernet applications such as Microchip, Texas Instruments, Broadcom, and Linear Technology.
