Distinguished by its center key polarization, this header features gold-plated PCB posts (1.0 micrometer) for reliable solder joint formation and tin-over-nickel plating on mating contacts. Validated to USCAR-2 specifications, the connector meets stringent requirements from major global automotive OEMs. The grey 30% glass-filled SPS housing provides UL94 V-0 flammability rating and operates reliably from -40\u00b0C to +105\u00b0C. With a 10A per contact rating and 500V voltage rating, this connector is well-suited for automotive power and signal distribution applications.","working_principle":"The 34691-0161 operates as a wire-to-board interconnect:\n\n1. Contact System: 0.64mm square pins with brass construction mate with female terminals, establishing electrical contact through spring-force engagement with tin-over-nickel plating.\n\n2. PCB Interface: Gold-plated (1.0 micrometer) posts provide reliable solder joint formation during through-hole assembly.\n\n3. Polarization: Center key ensures correct mating orientation, preventing incorrect connections per USCAR standards.\n\n4. TPA Locking: Terminal Position Assurance devices prevent contact back-out during vibration and thermal cycling, ensuring long-term reliability.","pin_description":"<table>\n<tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>1-8<\/td><td>Signal Row A<\/td><td>Signal<\/td><td>0.64mm signal pins - row A connections<\/td><\/tr>\n<tr><td>9-16<\/td><td>Signal Row B<\/td><td>Signal<\/td><td>0.64mm signal pins - row B connections<\/td><\/tr>\n<\/table>\n<p>Note: Pin numbering follows USCAR standard. 16-circuit header uses 0.64mm pins in 2-row x 8-position arrangement on 2.54mm pitch.
