STF202: USB Upstream Port Filter and TVS for EMI Filtering and ESD Protection

The STF202-22/30 is a combination EMI filter and line termination device with integrated TVS diodes for use on upstream USB ports.  It is constructed using a proprietary technology that allows passive components and TVS diodes to be integrated in the same package.  Each device will provide termination, filtering, and ESD protection for one upstream USB port.
