SRF2012A Common Mode Chip Inductors Bourns SRF2012A Common Mode Chip Inductors are designed to attenuate unwanted noise frequency in high-speed signal lines such as USB 2.0, IEEE1394 and LVDS which are used in PCs, PC peripheral devices, LCD panels and other electronic devices. The Bourns SRF2012A Common Mode Chip Inductors are wound on a ferrite core which provides low DCR, high-rated current and high common mode impedance.
