Rectangular Connectors are widely used in a variety of applications that require electrical connections between two electronic devices. The most common type of rectangular connector is the header, which includes a male pin or socket that serves as an electrical connection point. Headers are usually used in printed circuit boards (PCB’s) and can provide up to four connections. The 71991-620LF variant of the header is an extremely versatile type of connector that can be used in a variety of applications.

The 71991-620LF header is a surface mount component with a total of 20 pins, arranged in two rows with 10 pins each. It is constructed from a durable, thermoplastic, white UL94V-0 rated material, with gold-plated copper contacts and an operating temperature range of -55°C to +85°C. This header is designed to be extremely reliable, with an insertion force rating of 0.4N and an optimal contact resistance of 10mΩ. The 71991-620LF has a wide variety of applications, one of the most common of which is as a connector in Printed Circuit Board (PCB) assemblies.

In PCB applications, the 71991-620LF headers are typically used to connect two different boards together, with the male pins on one board being inserted into the female sockets on the other. The female sockets may be soldered, clamped, or screw-attached to the PCB. This type of connection is commonly used in server, communication, automotive, consumer and medical electronics systems.

The working principle of the 71991-620LF header is based on mechanical contact between the male pin and the female socket. When the pin is inserted into the socket, the two components are joined together, creating an electrical connection that allows current to flow between the two boards. The gold-plated contacts ensure that the connection is not lost over time, and the thermoplastic material protects against interference. This ensures a reliable and robust connection over the long-term.

The 71991-620LF header is a versatile and reliable rectangular connector that is used in a variety of applications. It is constructed from durable materials and has a wide operating temperature range. The header works by connecting two boards together through the use of male pins inserted into female sockets, creating an electrical connection. This ensures a dependable connection over the long-term, making it a popular choice for a wide range of applications.
