Product details

Current rating and termination

Termination is through-hole with a kinked pin — the kink provides a press-fit retention during soldering, holding the header in place before wave or hand solder. The post length of 0.125" (3.18 mm) suits standard 1.6 mm (0.062") PCBs.

The natural colour indicates no added pigment, typical of standard production parts.
