INTEGRATED DEVICE PROVIDING OVERCURRENT AND OVERVOLTAGE PROTECTION AND COMMON-MODE FILTERING TO DATA BUS INTERFACE

摘要

An electrical component includes a mounting substrate (40), a common-mode rejection filter (62) mounted to the substrate, and at least one circuit protection element mounted to or formed by the substrate. The circuit protection element may provide a PPTC resistor element (100) for overcurrent protection and/or a spark gap NTC element for overvoltage protection. The substrate includes a plurality of contacts including filter contacts connected to the common-mode rejection filter, and protection contacts connected to the protection element, the electrodes enabling surface mounting and connection of the component to aligned connection features of a host printed circuit board.
