FEATURES AND SPECIFICATIONS Molex offers the Fully Buffered DIMM with color options for server applications. The development of Fully Buffered DIMM (FB DIMM) came from the need for larger and faster memory capacity where memory coordination and accuracy at high speeds are critical which DDR2 is not capable of supporting. The FB DIMM is a variant of the DDR2. It combines the high-speed internal architecture of DDR2 with a bi-directional point-to-point serial memory interface which links each FB DIMM module together in a chain. The difference is here in which the DDR2 uses a single memory bus. Molex is an active member of the JEDEC work group that defines industry standards for memory. This allows Molex to ensure that all our memory sockets are 100% industry compatible. 1.00mm (.039") Pitch Fully Buffered DIMM Socket 240 Circuit With Color Options 48206 Vertical, Through Hole Features • High-temperature thermoplastic housing • Accepts JEDEC defined module MO-256 • Complies with JEDEC SO-003 socket specifications • Dual ejector latches • Built in end key design • Latch tower support • Beveled metal pins (forklocks) Benefits • Lead-free process compatible • Ensures 100% industry compatibility • Ensures easy module insertion and removal with minimal micro motion • Ensures correct insertion of FB memory module • Aids in keeping the module vertical • Provides proper socket to PCB alignment and retention, during and after soldering SPECIIFICATIONS Reference Information Packaging: Tray UL File No.: TBD CSA File No.:TBD Mates With: JEDEC MO-256 memory modules Complies with: JEDEC SO-003 Socket Outline Designed In: Millimeters Electrical Voltage: 30V Current: 0.5A Contact Resistance: 20 milliohms max Dielectric Withstanding Voltage: 500V AC Insulation Resistance: 1000 Megohms min Mechanical Contact retention to housing: 3N min (Contact) 13N min (Forklock) Insertion Force to PCB: 0.56N (0.13lb) Mating Force: 0.81N (0.18lb) Unmating Force: 0.02N (0.01lb) Latch Actuation Force: 45N max per latch Durability: 10 Cycles Physical Housing: See order table Flammability rating: UL 94V-0 Contact: Copper (Cu) Alloy PCB thickness: 1.60mm (.062”) Plating: Contact Area — See order table Solder Tail Area —Tin (Sn), Lead-free Underplating — Nickel Operating Temperature: +260°C max. MARKETS AND APPLICATIONS Computing – High-end workstations Servers – Blade servers – Rack-optimized servers – Mainframe Telecommunications – Routers – Switches 1.00mm (.039") Pitch Fully Buffered DIMM Socket 240 Circuit With Color Options 48206 Vertical, Through Hole Server Telecommunications Router High-end Workstation ORDERING INFORMATION 1.00mm (.039") Pitch Fully Buffered DIMM Socket 240 Circuit With Color Options 48206 Vertical, Through Hole Description Lead-Free Ordering 48206-0001 48206-0002 48206-0003 Plating 0.38µm (15µ") Gold (Au) 0.76µm (30µ") Gold (Au) 0.38µm (15µ") Gold (Au) Features Solder Tail Length Latch Color Housing Recommended PCB Thickness 2.67mm (.105") 0.76µm (30µ") 48206-0004 Gold (Au) 48206-0005 48206-0006 Gold (Au) Flash Gold (Au) Flash 0.38µm (15µ") Gold (Au) 0.76µm (30µ") Gold (Au) 0.38µm (15µ") Gold (Au) 0.76µm (30µ") Gold (Au) Gold (Au) Flash Gold (Au) Flash 0.38µm (15µ") Gold (Au) 0.76µm (30µ") Gold (Au) 0.38µm (15µ") Gold (Au) 0.76µm (30µ") Gold (Au) Gold (Au) Flash 3.18mm (.125") White Nylon 4/6, Black 1.60mm (.062") 2.67mm (.105") 3.18mm (.125") 2.67mm (.105") 2.67mm (.105") 3.18mm (.125") Black 3.18mm (.125") 2.67mm (.105") 3.18mm (.125") 2.67mm (.105") 2.67mm (.105") 3.18mm (.125") White 3.18mm (.125") 2.67mm (.105") 48206-0101 48206-0102 FB DIMM Socket, Vertical, with 48206-0103 Beveled Metal Pins, 48206-0104 1.8V Center 48206-0105 48206-0106 48206-9001 48206-9002 48206-9003 48206-9004 48206-9005 Nylon 4/6, Black 1.60mm (.062") Nylon 6/6, Blue 1.60mm (.062") Bringing People & Technology Together, WorldwideSM Americas Headquarters 2222 Wellington Ct.
