Product Introduction
The JST B2PS-VH(LF)(SN) is a 2-position male pin header from the VH series, designed for board-to-cable/wire interconnects. It uses a 3.96 mm pitch, a single row of square pins, and a shrouded 1-wall design with a locking ramp for secure mating. The right-angle through-hole orientation makes it a natural fit for board-edge connections where the cable exits parallel to the PCB. Rated at 10 A per circuit and 250 V, it handles moderate power loads in a compact 2-position footprint.
What the Ratings Mean for the Fit
The 3.96 mm pitch is the key dimension for PCB layout — it sets the pad spacing and determines compatibility with the mating VH receptacle housing. The 10 A per circuit rating is a solid power figure for a 2-position header, but it's derated above the 85°C operating ceiling, so keep the ambient temperature in check if you're running near the limit. The tin-on-tin contact finish (mating and post) is fine for moderate mating cycles in a clean environment; it won't match gold for corrosion resistance in aggressive atmospheres, but for a general-purpose wire-to-board connection inside an enclosure, it's the standard choice.
Mating and Termination
This header mates with the JST VH series receptacle housings that accept crimp terminals — the locking ramp on the header engages the receptacle latch for vibration-resistant retention. Termination is through-hole solder, with a 0.142" post length that suits standard PCB thicknesses. The 1-wall shroud guides the mating connector and protects the pins from accidental shorting during handling.
