Bourns SM42002EL/SM42P01EL/SM43001EL/SM43P01EL LAN transformers

Bourns has introduced the model SM42002EL, SM42P01EL, SM43001EL and SM43P01EL gigabit ethernet chip LAN 1G/2.5G/5G and 10G BASE-T transformer modules with PoE+ available.

Each transformer module is constructed with four discrete chip LAN transformers and four common mode chokes assembled on a PCB with a ferrous metal shield which offers customers a quick and simple assembly solution. These modules are pin-to-pin compatible with the traditional potted case LAN transformer and offer a lower profile and superior coplanarity. With a common mode choke paired with each transformer, the module offers a high degree of attenuation for EMI suppression. 

These chip LAN transformer modules are compliant with IEEE 802.3 and are ideal for use in LAN interfaces for a variety of high-speed telecommunication and network devices.
