This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.



Bourns SM453229A-381N7Y AEC-Q LAN Transformers

Bourns SM453229A-381N7Y are IEEE 802.3 Ethernet compatible network transformers.

These transformers are both Automotive-Grade 10, 100, and 1000 Base-T compatible.

Unlike traditional LAN transformers made using multiple toroidal core transformers and common mode chokes, Bourns Automotive Grade Transformers utilize a discrete, center-tapped component wound on a drum core.

This design feature enables the transformers to emulate the result of a toroid core with a closed magnetic path, with the added benefit of a high degree of PCB layout flexibility.

These transformers feature a HiPot isolation of 1500 VAC, a temperature range from -40°C to +105°C and can be paired with the  SRF2012A-801Y common mode choke for EMI reduction.

The network transformers are ideal in ethernet, telecommunication, and network device applications.
