It carries a 3.96mm pitch, rated 10A per circuit at 250V, with tin-plated square male pins. The right-angle through-hole orientation suits board-edge layouts where the wire exits parallel to the PCB. A locking ramp on the shroud provides positive retention against vibration — you should hear it click when the mating housing seats fully. ## What the Ratings Mean for Your Fit The 3.96mm pitch gives enough creepage for the 250V rating without forcing an oversized board footprint — it's a middle-ground spacing that handles power without wasting real estate. The 10A per circuit rating is the headline figure for wire gauge selection; at this pitch and current, 18 AWG is typical for the mating crimp terminal. The tin-on-tin contact finish (mating side and post) is fine for moderate mating cycles in a harness that isn't disconnected frequently — gold would buy you nothing here unless the environment is corrosive. The locking ramp is the key retention feature: if the mating housing doesn't click, the connection isn't fully seated. ## Construction and Compliance The housing is molded in natural polyamide (PA66 / Nylon 6/6) with a UL94 V-0 flammability rating — required for equipment inside an enclosure. Brass contacts with tin plating on both the mating surface and the solder tail. Operating temperature range is -25°C to 85°C, which covers most indoor industrial and consumer environments but not extended automotive under-hood duty. The single-wall shrouding protects the pins during mating but doesn't fully enclose them on all sides.","metaTitle":"JST B3PS-VH(LF)(SN) VH Header, 3-Position, 3.96mm Pitch","metaDescription":"JST B3PS-VH(LF)(SN) VH series header, 3 circuits, 3.96mm pitch, 10A, 250V, tin-plated contacts, locking ramp.
