NEW Micro-Miniature Interface Connectors For Power Supply/Signaling MQ172 Series 3 positon size 4 position size Fatures Space saving 1. Ultra Miniature/Low Profile SMT Design 3 Position type With dimensions of 3.9mm(H) x 6.4mm (W) x 6mm (D) for the 3 contact type, this series is ideal for todays miniature, lightweight electronic products. 2. Automatic Mounting: SMT receptacles are packaged in embossed tape and reel for automatic pick and place installation. 3. Reliable contact: The 2-point contact design and lead construction provide a contact which is resistant to vibration and shocks. 4. High current capacity: Unique contact design ensures high current capacity (e.g., 3A for 3- position), small as it is. 5. Positive Locking Applications Use of a snap-lock system provides the sensation of locking at the time of insertion. 6. Wide variety of suitable cables: A wide selection of cable types can be utilized since the plug is of the soldered wiring type. Additionally, the plug case and cord bushing are integrated into a one piece body, allowing for easy assembly by simply pressing the case into place after the harness work. 6. Keys for preventing incorrect insertion: Both 3 and 4-contact types have keys to prevent incorrect insertion. Applications Portable remote terminals, portable telephones, PHS(personal handy phone system), Notebook PCs, Electronic measuring instruments, etc. 2009.2 03/20091The product information in this catalog is for reference only.
