FFC, FPC (Flat Flexible) Connectors, a small but essential component in wide range of electronic systems, has become a versatile and ubiquitous contact system. The 77727-401LF flat flexible contact, manufactured by TE Connectivity, is designed to be one of the market\'s ultimate contacts and connectors for laptop and port applications.

The 77727-401LF contact is designed to reliably interconnect and mount flat flex systems for laptop applications and ports. This contact has a 2.75mm² high pitch FFC pitch and a 0.5mm centerline that provides a remarkably and highly reliable contact. The contact features gold plating on the connector’s solder tails for improved contact resistance and corrosion immunity and a nitride finish on the mating pins for increased wear resistance. It also has a standard pitch size of 0.5mm between the FFC pin and the mating pin to ensure robust connections with FPC.

This flat flexible contact is designed to meet, or exceed, the IEC 60335-1:2015 standard, which requires that the contact must self-release in the event of an accidental short. It also meets the UL 1977 standard which requires that the contacts must withstand over 1,000 mating cycles without causing any significant degrading of their contact resistance. Furthermore, the TE Connectivity 77727-401LF contact is rated at 2.5A current and 250V voltage and is capable of providing reliable connections in applications with temperatures up to 85°C.

The 77727-401LF contact is widely used in various laptop and portable system applications due to its ease of installation, reliability, and low profile. The contact’s low profile design minimizes the overall height of the system, allowing for the installation of larger components, resulting in increased utilization of space. Additionally, its highly reliable dual beam contact structure had minimized the discrepancy between mated contacts during the mating process, while its quick and reliable release mechanism allows for quick and safe disconnection from the device.

In summary, the 77727-401LF flat flex contact is an advanced and reliable contact system. This contact has a 0.5mm centerline, gold plated casing and nitride finished pins for improved contact resistance and corrosion immunity. It is designed to meet the UL1977 and IEC 60335-1:2015 standards and is capable of providing connections with 2.5A current and 250 Volts. Moreover, it is easy go install and provides a low profile design, allowing for maximized component installation. This makes it a great choice for laptop and port applications.
