In telecommunications applications such as modems for computers, notebooks, and servers, protection of circuitry is needed to prevent equipment damage caused by over-voltage and over-current surges due to line voltage surges, lightning strikes and/or AC power cross disturbances. Fully matched and compatible with PMC-Sierra's transceivers when used with recommended chip side protectors, the PulseJack RJ-45 connector has been designed to meet the surge immunity and electrical safety standards, including Bellcore GR-1089, FCC Part 68 and UL 1949/1950.
With integrated magnetics, voltage surge protectors, and over-current protectors, the new PulseJack RJ-45 connectors deliver improved electrical performance and a built-in RJ-45 receptacle in one package. The PulseJack is a space efficient module, which minimizes the electrical trace length between the RJ-45 connector and Integrated Circuit Transceiver, again improving both electromagnetic interference (EMI) protection and electrical performance.
The transfer-molded connector module utilizes Pulse's patented interlock base construction, which minimizes the stress of human handling during assembly and encapsulation, thus resulting in more uniform positioning of coils, leads and interconnecting wires which in turn provides a higher part quality and reliability.
Packaged, the PulseJackRJ-45 connector, part number J1501F21, has an inductance value of 0.6 μH, with turn ratios of 1:2,42 for transmission and 1:2,42 for receiving. IC grade transfer-molded package withstands 235°C IR reflow. Operating temperatures are 0°C to +70°C.
