D3918-42

Sockets for ICs, transistors and other components are essential for engineers and hobbyists who want to build electronic circuits. D3918-42 is one such device that is designed for use in different applications. This article will discuss the application fields and working principle of the D3918-42 socket.

Application Fields of D3918-42 Socket

The D3918-42 is primarily used as a socket for consumer, automotive and industrial applications. The socket is designed for use with all types of 8- and 16-bit microcontrollers, FPGAs, ASICs, and other components that have a flat bottomed or oval-shaped footprint.

The device is also used in robotic systems, communication systems, and medical equipment as a socket for various sensors, transducers, and other electronic components. The socket provides connection between different types of boards, such as CPU boards, system boards, and I/O boards. Additionally, it can be used as a connector in data acquisition systems, for testing and characterization. Last but not least, the socket is also used in automotive and consumer applications where it serves as a reliable interface between motherboards, daughter boards, and other components.

Working Principle of D3918-42 Socket

The D3918-42 socket is securely mounted onto a motherboard, daughter board, or system board using solder or mounting screws. It consists of two mating parts: the socket and the plug. The socket contains two sets of contacts: the upper contact and the lower contact. The upper contact consists of four low-profile, spring-loaded contact pins that make contact with the mating plug.

When a plug is inserted into the socket, the upper contact pins press down on the plug while the lower contact pins press up. This creates a secure electrical connection between these pins, which allows power and data to flow in both directions. The lower contact pins also provide a secondary connection, providing additional stability and preventing the plug from disengaging from the socket when subjected to vibration.

The socket is designed to ensure reliable performance in a wide range of environmental conditions, such as high and low temperatures, humidity, and dust. Additionally, the contacts are corrosion resistant and have a long operational life.

Conclusion

The D3918-42 socket is a versatile device that is designed to provide reliable connections in a wide range of applications. It consists of two mating parts, the socket and the plug, which securely and reliably make contact when inserted into the socket. Additionally, the socket is designed to perform reliably in a range of environmental conditions, ensuring a long operational life.
