Data Sheet FUJITSU Component Connector FCN-074B / 078B series (DDR4 DIMM)
FUJITSU Component Connector FCN-074B / 078B series Card Edge Connector for DDR4 Memory Module RoHS compliant
Overview This is a 288-pin DIMM socket that conforms to JEDEC standards. Features ■■ Highly reliable contact Contact reliability with a module substrate is improved by a Fujtisu proprietary double-contact structure, which is resistant to dust and flux ■■ Various terminal shapes to match with substrate design and mounting form One surface mount type, one press fit type, and three through-hole types having different terminal lengths are included in this lineup ■■ Flame resistant UL94V-0 Flame resistant UL94V-0 LCP resin is used for the housing insulating material ■■ Typical applications DRAM-memory module connections for HPCs (servers, supercomputers), communication measurement apparatuses and office equipment
