It is designed to accept Express Mini Cards (PCIe Mini Card) and complies with the PCI-SIG industry standard for high-speed data expansion in computing platforms. The 0.8 mm pitch, 2-row contact arrangement provides 52 connections for data, power, and control signals. Gold-plated copper alloy contacts rated at 5 A ensure reliable signal integrity for high-speed PCIe data transmission. The right-angle SMD termination enables low-profile mounting on the PCB, suitable for notebook and desktop computer motherboards.","working_principle":"The 1775838-2 operates as a card edge socket that accepts a Mini PCIe expansion card. The card edge connector design uses spring-loaded contacts that press against the gold fingers on the PCIe Mini Card when it is inserted into the slot. The 52 contacts are arranged in two rows (A and B) on 0.8 mm pitch, providing connections for PCIe data lanes, USB interface, SMBus, power rails, and control signals. The right-angle orientation mounts the card parallel to the motherboard surface, minimizing the Z-height requirement. The contact design provides stable normal force for reliable connection even under mechanical shock up to 50G.","pin_description":"
