Female header, a type of connector.

1. Application: This type of connector is widely used in PCB circuit boards in electronics, electrical appliances, and instruments.

2. Function: Its function is to serve as a bridge between blocked sections within a circuit or between isolated, non-conducting circuits, undertaking the task of current or signal transmission. It is usually used together with a female header to form a board-to-board connection; or used together with the end of an electronic wire harness to form a board-to-wire connection; it can also be used independently for board-to-board connection.

3. Classification: According to pitch, it can be roughly divided into seven types: 0.8mm, 1.0mm, 1.27mm, 2.00mm, 2.54mm, 3.96mm, and 5.08mm (other special pitches can also be customized as needed); according to the number of rows, there are single-row female headers, double-row female headers, triple-row female headers, four-row female headers, etc.; according to packaging usage, there are SMT surface mount, DIP through-hole (straight/right-angle), etc.; according to installation method: 180 degrees, 90 degrees, SMT; according to whether height increase is needed and whether positioning posts are needed, there are 2 types of positioning posts, one is an inner positioning post, and the other is an ear positioning post; female header terminal types: U terminals and Y terminals (U-shaped terminals, with contact on 3 sides, are generally used for low plastic height; Y-shaped terminals, with contact on 2 sides, are generally used for high plastic height).

Note: Please insert and remove the pin header and female header slowly, especially when removing the pin header, try to ensure that both ends of the pin header can come out at the same time, so as to avoid damaging the pins.
