The JST B7PS-VH(LF)(SN) is a 7-position, single-row header from the VH series, designed for board-to-wire power interconnects. It uses a 3.96 mm pitch — wide enough to handle the 10 A per circuit rating without crowding the board layout. The right-angle through-hole termination keeps the wire exit parallel to the PCB, which suits enclosures where height above the board is limited. A locking ramp on the shroud provides positive retention against the mating receptacle housing, important in harness assemblies subject to vibration.
What the ratings mean for fit
The 3.96 mm pitch is the first thing to check against your board footprint — it's wider than the 2.54 mm common on signal headers, so the pad spacing and routing channels need to match. The 10 A per circuit is genuine power-level current, but the tin-on-tin contact plating (mating and post both tin) means the connector is built for a limited number of mating cycles — fine for a permanent or occasional-service harness, not for frequent disconnect-reconnect duty. The 250 V rating gives enough headroom for most low-voltage DC and AC power rails inside equipment. The UL94 V-0 nylon 6/6 housing meets the flame rating required for components inside a ventilated enclosure.
Mating and sourcing
This header mates with the JST VH series receptacle housing that accepts the appropriate crimp terminals — the locking ramp on the shroud engages the latch on the housing for a secure fit. The (LF)(SN) suffix in the order code indicates a lead-free (RoHS-compliant) finish. The base product number is B7PS-VH; the difference between B7PS-VH and B7PS-VH(LF)(SN) is the RoHS compliance and tin plating — the (LF)(SN) variant is the current standard for new designs requiring RoHS conformance.
