QFS-078-04.25-H-D-PC4

QFS-078-04.25-H-D-PC4 represents a type of rectangular-shaped connectors used in board-to-board (mezzanine) connections. These connectors are known as arrays, edge type, and mezzanine connectors and are often used in applications involved with transferring data and power from one circuit board to another. As such, they can be seen in many electronic devices such as computers, HDTVs, and mobile phones. This type of connector is typically made of copper, a durable and conductive metal, and is able to transfer power or data by creating a solid connection between two circuit boards.

The connectors are usually capable of transferring data rates up to 25 Gbps and power rating up to 5A, which makes them ideal for transferring data and power simultaneously from one PCB to another. In addition to that, it is also possible to get QFS-078-04.25-H-D-PC4 connectors with integrated retainer for better contact reliability. This is especially helpful when it comes to ensuring the best possible connection between two circuit boards.

As mentioned above, the connectors can be seen in many electronics devices due to their reliable performance and good contact reliability. They are commonly used in computers, HDTVs, and mobile phones for transferring data and power between circuit boards. In computers, they can be used for connecting a CPU and a motherboard or for connecting a hard drive to the PC. In HDTVs, they can be used for connecting a display board, a main board, and an audio board. In mobile phones, they can be used for connecting a logic board to a display board and vice versa.

In terms of working principles, QFS-078-04.25-H-D-PC4 connectors consist of an array of pins which are commonly arranged in a two row configuration. The pins, which are typically made of copper, provide the electrical connection between the two circuit boards. The pins are inserted into the receiving holes located on the edge of each circuit board.

In order to ensure a good connection between the two boards, the pins must be of the correct size and be correctly inserted. Additionally, most of these connectors also feature a retainer which helps to ensure that the pins are inserted to the correct depth. The retainer also helps to ensure that there is no damage to the pins or the circuit boards.

Overall, QFS-078-04.25-H-D-PC4 connectors are highly reliable and versatile types of rectangular connectors used in board-to-board (mezzanine) applications. They offer good contact reliability and can transfer data and power simultaneously between two circuit boards. As such, these connectors can be seen in many electronic devices such as computers, HDTVs, and mobile phones, and can be used for connecting a CPU and a motherboard, a hard drive to the PC, a display board, a main board, and an audio board in an HDTV, and a logic board to a display board in a mobile device, respectively.
