ESQT-149-03-L-Q-309

ESQT-149-03-L-Q-309 is a part of the Rectangular Connectors – Headers, Receptacles, Female Sockets manufactured by TE Connectivity Solutions. This part is a three-row linear right angle female socket with a terminal density of 149 pins per row, and a pitch of 0.3”.

Application field

ESQT-149-03-L-Q-309 is mainly designed for applications requiring board-to-cable interconnections, like signal, power, and control interface. This product can be used in a lot of PCB standard applications, such as communication, consumer electronics, computer, automotive, industrial, and medical equipment.

Working principle

ESQT-149-03-L-Q-309 works in the same way as other rectangular connectors – by providing secure contact and electrical connection between two circuits. Its terminal structure features two connecting plates, one connected to a printed circuit board, and the other connected to a cable or separate device, thus connecting them together. Both the terminals and the latch structure feature a stamped and formed copper alloy design for reliable performance.

ESQT-149-03-L-Q-309 is designed with an Unterminated polarization option, which helps keep the mating terminals in the correct position during mating. It also has a positive latching system for secure end-to-end mating. The terminal pins have an insulation displacement contact (IDC) design to ensure superior durability and electrical performance.
