71991-323LF

Rectangular Connectors – Headers, Receptacles, Female Sockets, are an important component while assembling electronic products. Used in industrial, industrial control and automation, computers, consumer electronics and other electronic equipment, these connectors are incredibly versatile in terms of application and function. The 71991-323LF is one such component that can be used for a wide range of applications. This article will explain the application field and working principle of the 71991-323LF.

The 71991-323LF is a socket header type of rectangular connectors. Socket header type of connectors keeps the electrical and physical connection between a PCB and components, sockets and headers, allowing the mechanical and electrical connection for integrated circuits and other components. It has a rated voltage of 600V and a contact current of 3A. It is made of UL94V-0 rated nylon material with a nickel plated finish. It also has gold plated contacts with a temperature range of -25 °C to +105 °C.

The particular 71991-323LF is used for applications where space constraints necessitate mid-wall mounting. Its design consists of a socket with an internal post that is mounted on a PCB thus ensuring secure connection and reliable contact with IC pins. It has 4 pins that provide the connections. The socket has an inclined sloping wall instead of vertical walls, and includes a screw in the middle that is fastened to the PCB for mounting. The inclined sloping walls of the 71991-323LF also provides strain relief in case the wires are being pulled externally.

In terms of working principle, 71991-323LF works by connecting power and signal between an IC and a PCB. Its 4 pins are inserted in four holes in the PCB board. The socket has two wings or ‘windows’ on either side of the pins where an IC chip is inserted. It also has a strain relief which holds the wire securely and prevents it from being pulled off of the socket. This ensures a reliable and secure connection between the PCB and IC chip.

The 71991-323LF is an ideal choice for a wide range of electronic applications such as consumer electronics, industrial control, automation, computers, and so on. Its design allows it to fit the stringent space constraints of many electronic products. It is also highly reliable and ensures secure and reliable connections, making it ideal for use in various electronic applications.
