Designed for high-speed Ethernet data applications, the company's new line of PulseJack surface-mount modular jacks incorporate different internal magnetic filter designs to accommodate various chipsets commonly found in 10/100Base-Tx NICs. The internal magnetic assemblies have been tested to deliver a minimum of 1.5kVrms HIPOT isolation.

With the required transformers, chokes, capacitors, and termination resistors already within the connector, the PulseJack series offer fewer component placements and requires less board space than traditional design options using separate components.

The single-port RJ-45 style jacks are available with either an up (J3 series) or down (JV series) locking tabs. They are designed to withstand IR reflow solder, and when used in NIC designs, eliminates secondary wave solder by excluding the remaining through-hole component.

The PulseJack connectors have a maximum insertion loss of -1dB (1MHz to 65MHz) and a minimum return loss of -12dB (60MHz to 80MHz). It has a CMRR of -30dB at 1MHz to 50MHz and -20dB at 50MHz to 130MHz. The connectors operate at a temperature range of 0C to 70C and comply with the IEEE 802.3 and ANSI X3.263 standards.

The PulseJack connectors are available with several LED options and are shipped in trays or tape-and-reel packaging. Shields are available with or without EMI tabs.
