Chip inductors designed for automotive audio bus apps

Bourns, Inc. announced its new 1210-size automotive-grade common-mode chip inductor series. Bourns’ latest family of common-mode inductors are designed with a ferrite core and are bifilar-wound to deliver a compact size and shielded construction. The Model SRF3225AB and SRF3225TAC common-mode chip inductor series offer low radiation and high impedance over a broad frequency range to suppress Electromagnetic Interference (EMI) entering or leaving the system making them excellent solutions for design-in and testing in consumer, industrial, and many other electronics applications.

The inductor core features a 0.2/0.3 mm height sidewall terminal at each end designed to help enhance the component’s mechanical strength after it is assembled on the board. Both model series are AEC-Q200 compliant for higher reliability and durability. The Model SRF3225AB is specifically designed for noise suppression in 2-wire UTP (unshielded twisted pair) cable automotive audio bus systems. Designers will find the SRF3225TAC series well-suited for common-mode noise suppression in typical CAN and higher data rate CAN-FD Class II applications.

The new Bourns Model SRF3225AB and SRF3225TAC series are available now and are RoHS compliant* and halogen-free**.
