The 1-770967-1 is a 3-circuit, in-line, right-angle PC board pin header for wire-to-board connections. It features a UL94V-0 flammability-rated white nylon housing and brass contacts. The contacts have a duplex finish, with gold in the mating area for reliability and matte tin on the solder tails for solderability, all over a nickel underplate. A board lock feature ensures secure attachment to the PCB. As part of the Mini-Universal MATE-N-LOK family, it belongs to a system rated for 600V AC/DC with a dielectric withstanding voltage of 1.5 KVAC. This compact and durable header is ideal for applications requiring secure and polarized connections.
