The 7490240120 1000Base-T SMT Transformer is designed for Ethernet
applications requiring Power over Ethernet (PoE) capabilities. This
transformer fully complies with the IEEE 802.3bt standard for
4PPoE, supporting up to 350mA per center tap (pins 1-18). The
transformer supports 1000 Base-T data transmission rates. It offers
excellent electromagnetic performance with optimized differential
to common mode rejection ratio, crosstalk, and common mode
rejection ratio across various frequency ranges.
The 7490240120 is designed to operate reliably across a wide
temperature range from -40°C to +105°C and has achieved multiple
certifications, including RoHS, REACH, and cURus, ensuring
compliance with global standards for safety and environmental
protection.
This SMT transformer is ideal for medical equipment, industrial
Ethernet applications, and other systems requiring high-speed data
transmission with robust electrical isolation and PoE
functionality.
Engineered with medical-grade safety features, the 7490240120 fulfills IEC60601 requirements for 1xMOPP (Means of Patient Protection) for working voltages up to 250 Vrms. It features an exceptional insulation test voltage of 4000V (RMS), making it suitable for applications where electrical isolation is critical. With a clearance distance of 2.5mm and creepage distance of 4mm, this component meets stringent safety requirements for electrical spacing.
