DIMM SOCKET s.o. DIMM SOCKET & DDR SOCKET memory module sOCKETs Introduction: Adam Tech DIMM (Dual in Line Memory Module) , S.O. DIMM (Small outline DIMM) & DDR (Double Data Rate) sockets are precision designed sockets for add-on memory modules. Offered in SMT & straight plug in mounting, their precision formed bellow style contacts are manufactured with extremely close tolerances for superior, precise alignment during mating. The DIMM and DDR latching sockets have a smooth actuation and a positive, audible sound to determine proper insertion. Features: 184 contacts on high density .050" Centerlines Complies with JEDEC specifications Available in five key versions Latches function both as Lock & Ejector Mating Options: All industry standard memory modules Specifications: Material: Standard insulator: Glass reinforced, rated UL94V-0 Optional Hi-Temp insulator: Nylon 6T, rated UL94V-0 Latch: Nylon 66 rated UL94V-0 Insulator color: DIMM & DDR: Black SO DIMM: White Contacts: Phosphor Bronze Contact Plating: Gold over nickel underplate in contacts area, tin over copper underplate on solder tails Electrical: Operating voltage: 250V AC max. Current rating: 0.5 Amp max. Contact resistance: 30 mΩ max. initial Insulation resistance: 1000 MΩ min. Dielectric withstanding voltage: 500V AC for 1 minute ORDERING INFORMATION DIMM 168 SERIES INDICATOR DIMM =DIMM Socket DDR = D ouble Data Rate Socket Mechanical: Insertion Force: 4 oz max Withdrawal Force: 1 oz min Temperature Rating: Operating temperature: -55°C to +105°C Soldering process temperature: Standard insulator: 235°C Hi-Temp insulator: 260°C V Mounting V= Straight PCB Mount (DIMM & DDR) R= Angled (DDR) S= SMT Positions 168= DIMM 184= DDR 200= DDR 240= DDR3 Packaging: Anti-ESD plastic trays Voltage Key 1 =3.3V 2 =5.0V (DIMM & DDR only) 3 =2.5V 4 =1.5V 5 =1.8V Approvals and Certifications: UL Recognized & CSA Certified, File no.
