The JST B6P-VH-FB-B is a 6-position, single-row header from the VH series, designed for board-to-cable/wire power interconnects. It carries a 3.96 mm pitch and is rated for 10 A per circuit at 250 V, making it a solid choice for internal power distribution in appliances, industrial controls, and power supplies. The header is through-hole soldered, with a shrouded 4-wall design and a locking ramp that provides positive retention against vibration.
What the ratings mean for the fit
The 10 A per circuit rating at 250 V is a genuine power-level spec — this header is sized for feeding a DC rail or driving a small motor, not just passing signal. The 3.96 mm pitch gives adequate creepage for the 250 V rating without an oversized footprint, and the single-row layout keeps the board area tight. The tin-plated contacts on both mating and post sides are standard for this duty class; tin is reliable for a moderate number of mating cycles in a clean environment, but if the application sees frequent reconnection or corrosive conditions, a gold-plated variant would be worth considering.
