Bourns SRF3225AB & SRF3225TAC Common Mode Chip Inductors

Bourns SRF3225AB and SRF3225TAC 1210 Automotive-Grade Common Mode Chip Inductors are constructed with a ferrite core and are bifilar-wound. These design features allow Bourns SRF3225 Common Mode Chip Inductors to deliver a compact size and shielded construction for low radiation and high impedance over a broad frequency range for EMI suppression. SRF3225AB and SRF3225TAC are AEC-Q200 compliant for high-reliability and high-durability applications. SRF3225AB provides noise suppression in 2-wire UTP cable automotive audio bus systems. SRF3225TAC is designed for common-mode noise suppression for classic CAN and higher data rate CAN-FD Class II applications.
