Automotive Grade Chip LAN Transformer Offers PCB Layout Flexibility


Advanced features make Model SM453229A-381N7Y 10/100/1000 Base-T Chip LAN Transformer ideal for EMI suppression and Ethernet-based applications

Bourns, Inc., released its automotive grade Model SM453229A-381N7Y 10/100/1000 Base-T Chip LAN Transformer. Designed for maximum PCB layout flexibility, Bourns' latest Chip LAN Transformer model is a low-profile discrete solution. It is also AEC-Q200 compliant featuring an expanded temperature range of 40 to +105 °C, is capable of Hi-Pot isolation of 1500 VAC/60 sec., and is able to withstand pulse voltages of up to 2400 V, 1.2/50 μs.

These features make the Model SM453229A-381N7Y ideal for 10/100/1000 Base-T Ethernet networks, industrial single pair Ethernet and IEEE 802.3 Ethernet-based applications, and pairing common mode chip inductors for EMI suppression. This small, center-tapped transformer is wound on a drum core and capped with a ferrite plate to emulate the close magnetic path of a toroid core.

The center tap allows for common mode suppression even without an extra common mode filter. This discrete shielded transformer helps to reduce efforts in EMI troubleshooting. Bourns' fully automated production process contributes to a higher degree of component uniformity, and promotes consistent quality and improved reliability. High-volume, cost-effective production can be achieved with a shorter production lead time because of this automated production process. Bourns SM453229A-381N7Y 10/100/1000 Base-T Chip LAN Transformers are available now and are RoHS compliant and halogen free.
