77315-118-21LF Application Field and Working Principle

The 77315-118-21LF is a low-profile surface mount header from Molex brand. It is part of the Rectangular Connectors - Headers, Male Pins category. These Male Pin headers have a dual row design and are available with various pins count: 11, 12, 14, 16, 18, 20, 22, 24, 26, 30.

This 77315-118-21LF header has a total of 10.50mm (0.4134") height when mated, making them able to fit in tight spaces and board-to-board applications. Additionally, they feature HPC (High Performance Contact), which allows higher current rating per contact, compared to conventional technologies.

Internal pawl lock ensures that mating connectors remain locked until they are manually released. Furthermore, the 77315-118-21LF features rib support for a clear indication that the connector is properly mated. Furthermore, the internal metal shell in this male pin header offers reliability and a solid ground connection.

This 77315-118-21LF was designed and tested to be reliable against harsh environments and industrial settings. Molex product portfolio include a broad range of certifications, such as UL, CSA, VDE, CQC, PSE, plus temperature range certifications from -40ºC to +105ºC, making them perfect for a variety of challenging applications.

The 77315-118-21LF is part of the larger 77315 Chip Housing family, which also includes female right angle headers and receptacles. The range of applications for these connectors is thus wide, up to industrial and network communication related tasks.

The 77315-118-21LF is a female pin header intended to cooperate with any male pin plugs, equipments or cables, and it has applications for board-to-board mating, and other similar work. It is designed to fit boards with a free height of 11mm.

The materials used in this 77315-118-21LF connector are RoHS compliant, and the pin contacts are made out of copper alloy, gold plating on contact area with 0.76μm gold over 0.25μm nickel, and non-plated areas with 100μm nickel. The plastic insulator is made out of a UL94V-0 rated moulding compound.

The working principle of the 77315-118-21LF connector is pretty straightforward. As the cable or the male pin connector is plugged into the header, it is held in place by internal pawl lock, and the molecules of the gold coating produce an electrical connection between the two parts.

The 77315-118-21LF connector from Molex is a reliable and effective way to join two components that need to transfer electricity between them, for example between the board and a cable or another board. Its low-profile design, wide range of certifications and versatility make them ideal for a wide variety of applications.
