It is the receptacle that mates with the gold edge fingers on a standard PCIe Mini Card — the form factor used in embedded systems, industrial PCs, and telecom modules for Wi-Fi, cellular, SSD, and GPS cards. The 0.80mm pitch is tight enough to keep the card slot compact but still routable on a standard PCB with a 4-layer stack-up. Right-angle SMT orientation means the card sits parallel to the motherboard, saving vertical height in enclosures where the Mini Card is mounted on a carrier board. ## Why the 0.80mm pitch and 52 positions matter for your board layout The 0.80mm pitch is the PCI Express Mini Card standard — it is not a generic fine-pitch connector you can substitute with a different-pitch part. The 52 positions match the card edge contact count exactly; a 52-circuit Mini Card slot is the only position count that fits the standard card. The dual-row readout means the contacts alternate between the two rows along the slot, matching the staggered pad layout on the Mini Card edge. ## Contact finish and termination — what the gold flash means in practice Gold contact finish with flash thickness is standard for PCIe Mini Card slots. The gold layer on the mating surface prevents oxidation and fretting corrosion over the repeated insertion cycles a Mini Card sees during field service — swapping a Wi-Fi module or upgrading an SSD. The flash thickness is a thin gold deposit over the copper alloy base, adequate for the moderate mating cycle count of a card edge connector. Solder termination with surface-mount, right-angle mounting means the connector reflows in the same pass as the rest of the SMT components on the board. The Liquid Crystal Polymer (LCP) insulation handles the reflow temperatures without warping the slot body. ROHS3 compliance is confirmed, so it meets the EU RoHS exemption list for lead-free assembly.","metaTitle":"TE 1759503-1 PCI Express Mini Card Connector, 52 Pos, 0.80mm","metaDescription":"TE Connectivity 1759503-1 PCI Express Mini Card female connector, 52 positions, 0.80mm pitch, SMT right-angle, gold contacts, ROHS3.
