Bourns Announces 1210-Size Automotive Grade Common Mode Chip Inductors

March 21, 2021 by Hailey Stewart

Model PAC18R series features a shaft sealing for an enhanced ingress protection level and a precise rotational feel.

Bourns, Inc., a leading manufacturer and supplier of electronic components, today 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**. For additional product information, please see this link.

*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.
