Transformer module saves board space

13-05-2020 | Bourns | Subs & Systems

Bourns offers a new Chip LAN 10/100 Base-T Transformer Module to support Ethernet and LAN-based application developers save precious board space and improve design flexibility while satisfying dynamic data line demands. This new transformer combines two Model SM453229-381N7Y Chip LAN transformers and two Model SRF2012A-801Y common-mode chip inductors constructed on a PCB with a ferrous metal shield. This new model provides customers with a simplified assembly solution that is pin-to-pin compatible with the traditional potted case LAN transformer and produces superior coplanarity. Designers also have the versatility to employ just the transformer or the common mode choke separately, which provides further PCB placement freedom.

Built utilising a fully-automated, high capacity process, Bourns Model SM41126EL offers a consistent, extremely reliable and cost-efficient solution. The automated coil winding process is particularly significant as it ensures tight tolerances essential to electrical stability. This stability results in enhanced performance over a wide range of frequencies compared to manual winding processes. The low profile, small form factor module offers an expanded temperature range of -40C to +85C, and is fully compliant with IEEE 802.3 making it excellent for employment in LAN interfaces in a variety of telecommunication and network devices.

The module is available now and is RoHS compliant. Design tools are also available to assist in streamlining development.
