The Xmultiple surge protection RJ45 Series of connectors are designed to protect components which are connected to high speed data and telecommunication lines from voltage surges caused by lightning, electrostatic discharge (ESD), and electrical fast transients (EFT). The Xmultiple RJ45 surgre protection connectors utilizes technology for superior electrical characteristics at 3.3 volts. The capacitance of the connector is minimized to ensure correct signal transmission on high speed lines.

The surge protection series is designed to provide point-of-entry protection against power surges caused by external sources such as lighting strikes and substation switching. The surge protection series is a first stage protection connector utilizing primary protection in conjunction with a low surge protection filter integrated into the RJ45 connector. Pictured below is the surge protection circuit diagram.

Surge Protection is now emerging as a real-time concern of many users who want to protect their printed circuit boards from power surges. Preventing downtime of a network connection is one of the main advantages of providing surge protection. What makes surge protection magnetic jacks connectors so important is due to the fact that hey protect not only the electronic board of the networking equipment but in addition they protect the RJ connector. This is an important element of surge protection because the entry point of the networking equipment is the RJ45 connector. Therefore if the surge protection chips are located on the printed circuit board of the networking equipment the power surges enter the board and do not have a wall of protection until they reach the chips on the board. By having the chip located inside the RJ45 connector the power surge is stopped right at the point of entry to the networking equipment.
