75915-349HLF Datasheet/PDFRectangular Connectors - Headers, Receptacles, Female Sockets
The 75915-349HLF is an industry standard, low-profile, Surface Mount Interface (SMI) female socket which is especially designed for applications requiring a high-density, high current interface that is easily accessible from the top or bottom side of a circuit board or other type of substrate. This female socket can be used in a variety of applications such as Printed Circuit Board (PCB) interconnections, consumer audio components, automotive audio, communications, computing, industrial controllers, and Internet-of-Things (IOT) devices.
Application Fields
The 75915-349HLF is designed for applications requiring a low profile female socket that can easily be mounted from the top or bottom side of a PCB. The reduced profile allows for maximum design versatility when compared to traditional headers. The low-profile allows for tighter board design and reduces interference from components on the top side of the board. Additionally, the 75915-349HLF can also be used in other applications which do not require a lower profile, as it provides the same features and performance of traditional headers. It is suitable for use in products that need an interface system, such as communications, computing, industrial controllers, consumer audio, automotive audio, and Internet-of-Things.
Working Principles
The 75915-349HLF is a low-profile Surface Mount Interface (SMI) female socket featuring a 0.050 inch centerline overmold. The female socket is designed with a flexible-staggered pitch design to maximize board density and performance. This dual-row SMT Female Socket Interface has a press-fit channel for easy overmolding from the top or bottom side of a printed circuit board. The flexible-staggered pitch design is optimized for application areas that require higher current and more contacts than traditional headers. The socket has a machined pin contact with a tin-plated copper body and provides 0.63amp current carrying capacity.
The female socket interface allows for improved signal integrity and controllability when connecting components to the board. The design can support up to 500 mA of current and allows for a direct connection between the component and its substrate. The socket also provides improved durability, greater protection from shock, vibration and is able to withstand multiple insertion cycles. The female socket interface allows for a faster and easier assembly than traditional headers and is more expandable for larger packages.
The 75915-349HLF female socket is compliant to the industry standard IPC-4227C, and offers both horizontal and vertical mating solutions. The socket is also UL-rated, RoHS-compliant, Lead-free, and Halogen-free for optimized performance. Additionally, the socket is compatible with various types of automated installation processes, such as high-speed flexure-feeders and pick-and-place systems.
Conclusion
The 75915-349HLF is a low-profile surface mount female socket which offers a variety of features and benefits for use within PCB interconnects, consumer audio components, automotive audio, communications, computing, industrial controllers, and Internet-of-Things applications. The reduced profile and flexible-staggered pitch design allows for improved board density and easier installation, while the machined pin contact and 0.63amp current carrying capacity provides improved signal integrity and durability. The 75915-349HLF is UL-rated, RoHS-compliant, lead-free and halogen-free, making it an ideal choice for a variety of applications requiring a low profile female socket.
