Housing for a 3-Circuit Wire-to-Board Harness
The JST ADHR-03V-H is a 3-position receptacle housing from the ADH series, designed for free-hanging (in-line) wire-to-board or wire-to-wire interconnects. It accepts female blade socket contacts (ordered separately) and secures them with a friction lock that holds the mated pair against vibration without a secondary latch. The single-row layout at 0.051" (1.30mm) pitch keeps the footprint compact — useful when routing three circuits into a tight harness or board-edge connector. The PBT insulation material is rated for -25°C to 85°C.
Mating Half and Contact Selection
This housing mates with the matching ADH series pin header (male blade) — the header is the board-mount side, and the ADHR-03V-H is the receptacle that terminates the wire harness. Contacts are not included with the housing — you need to order the crimp terminals separately. The ADH series uses a female blade socket contact (stamped and formed, tin or gold plated depending on the application). The contact part numbers are not listed in this spec, but the terminal family is shared across the ADH series; the same crimp terminal works for 1.30mm pitch housings. Current rating depends on the contact plating and wire gauge — the housing itself does not limit current; the contact and wire do.
