The JST SUHR-03V-S is a 3-position, single-row receptacle housing from the SUH series. It's a free-hanging (in-line) shell that accepts female socket contacts via crimp termination — the contacts are ordered separately. The 0.80 mm pitch keeps the board footprint compact, which matters when routing traces between pads on a dense PCB.
Mating and Termination — What You Need to Wire It
This housing mates with the matching SUH series pin header — the friction lock holds the pair together against moderate cable tug or vibration, no secondary latch needed. The crimp terminals (female sockets) aren't in the bag; you order those separately by the SUH-series terminal part number. The 0.80 mm pitch means the header pins are close together, so use a crimp tool that seats the contact squarely to avoid bent pins on assembly.
