The Model SRF3225TABM and SRF3225TAFD common mode chip inductor work over a broad frequency range to suppress Electromagnetic Interference coming into or leaving the system.

Bourns announced the expansion of its line of 1210-size automotive grade common mode chip inductors. The new series filters complement Bourns' existing common mode chip inductor portfolio, and support higher data rate two wire bus systems in automotive, industrial and other electronic applications. The two new compact-sized series of Bourns common mode inductors are designed with a ferrite core and are bifilar-wound to deliver a shielded construction with superior common mode noise suppression.

The inductor core features a 0.3 mm minimum 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 providing reliability and durability. The Model SRF3225TABM-201Y is specifically designed to meet Open Alliance IEEE 100Base-T1 requirements, and 

Model SRF3225TAFD-101Y is well suited for common mode noise suppression in typical CAN and higher data rate IEC 62228-3 CAN-FD Class II transmission systems. This model also supports differential to common mode rejection (DCMR) for CAN FD Class III.
