Fujitsu Unveils FCN-078J Socket Connector

Fujitsu Components Europe has introduced a vertical, surface-mount DDR2 DIMM socket connector with an enhanced contact design and 0.1mm lead co-planarity. The 240-position FCN-078J-series card-edge socket features a patented split-beam contact structure that improves module mating reliability. As a memory module is inserted into the socket, the twin-contact's wiping action removes dust and flux residue and provides a robust connection between the module and socket, even in high-vibration environments.

Dual latching mechanisms ensure correct module retention and removal. The RoHS-compliant FCN-078J uses Fujitsu's own precision stamping and moulding technology to achieve 0.1mm co-planarity before and after reflow. This low-co-planarity specification contributes to improved manufacturing throughput yields. Applications include blade servers, switches, routers, telecom racks and test and measurement equipment to minimise occupied board space and improve air flow.

The FCN-078J socket measures 22.7mm in height by 140mm in length. It has an operating temperature range of -55C to +85C, a voltage rating of AC25V and a maximum current rating of 0.5A per contact. Heat-resistant tape on the top of the connector facilitates use with pick-and-place equipment. Solder bars in the middle and on the outside edges of the connector assure accurate IR processing when soldering the connector to the PCB.
