This file introduces the littelfuse mc line protector product, which can protect multiple twisted pairs from overvoltage conditions and is suitable for applications sensitive to load values.
The Multiport MicroCapacitance (MC) line protector is an integrated, multichip solution designed to protect multiple twisted pair connections from overvoltage conditions. It is specifically intended for applications sensitive to load values where high-speed connections require lower capacitance.
Based on a six-pin surface mount SOIC package, the device is equivalent to four discrete DO-214AA or two TO-220 packages. This compact design makes it ideal for densely populated, high-speed line cards that cannot afford PCB inefficiencies or the use of series power resistors.
