Product details

Three-position unshrouded header, 0.100-inch pitch

The through-hole solder termination and 0.295" (7.49mm) mating pin length suit it for standard PCB layouts where the header sits upright and the mating receptacle is pushed on from above. Rated at 250VAC, with current capacity depending on the wire gauge used in the mating terminal — the limiting factor is the crimp-to-wire interface, not the header pin itself.

Tin-plated contacts, UL94 V-0 housing

Both the mating contact finish and the solder post finish are tin-plated over a copper alloy base.
