Rated 0.5A per contact at 50V, with an operating temperature range of -30°C to 105°C, this connector suits low-current signal interconnects in compact board stacks. This header mates with a matching 1.25mm pitch receptacle (not included) using a push-pull fastening system; the 4-wall shroud guides alignment and prevents pin damage. The 0.049-inch (1.25mm) row spacing matches the pitch, so the dual-row layout occupies a 1.25mm x 1.25mm grid on the PCB.","metaTitle":"4-176891-4 TE Connectivity 1.25mm Pitch Header, 14 Pos, SMT","metaDescription":"4-176891-4 TE Connectivity AMP Connectors Fine Pitch header, 14 positions, 1.25mm pitch, SMT, shrouded, 0.5A, UL94 V-0.
