Bourns Expands Line of 1210-Size Automotive Grade Common Mode Chip Inductors

New compact and rugged inductors feature low radiation and high impedance over a broad frequency range delivering excellent EMI suppression

RIVERSIDE, Calif., August 3, 2021 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the expansion of its line of 1210-size automotive grade common mode chip inductors. The new Model SRF3225TABM and SRF3225TAFD common mode chip inductor series offer low radiation and high impedance over a broad frequency range to suppress Electromagnetic Interference (EMI) coming into or leaving the system. 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 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.

The Bourns® Model SRF3225TABM and SRF3225TAFD series are available now and are RoHS compliant* and halogen free**. For additional product information, please see:

*RoHS Directive 2015/863, Mar 31, 2015 and Annex.

**Bourns considers a product to be "halogen free" if (a) the Bromine (Br) content is 900 ppm or less; (b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less.
