Bourns, Inc. has announced the expansion of its line of 1210-size automotive grade common mode chip inductors with new SRF3225TABM and SRF3225TAFD Series, that offer low radiation and high impedance over a broad frequency range to suppress Electromagnetic Interference (EMI) coming into or leaving the system. These new compact-sized Series are designed with a ferrite core and are bifilar-wound to deliver a shielded construction with superior common mode noise suppression and support higher data rate two-wire bus systems in automotive, industrial, and other electronic applications. Moreover, these inductor's core feature 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 high 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.
