The 3.96 mm pitch is the key board-layout constraint — it matches the standard VH-series receptacle footprint and gives enough room between pins for a 250 V creepage path without forcing an oversized board. The 10 A per circuit is a per-contact limit; with all 4 positions loaded, the header can carry 40 A total if the PCB trace and wire gauge are sized accordingly. The locking ramp provides vibration resistance — it is the primary retention mechanism in a VH-series harness.","metaTitle":"JST B4P-VH-FB-B(LF)(SN) VH Header, 4 Pos, 3.96 mm, 10 A","metaDescription":"JST VH series 4-position shrouded header, 3.96 mm pitch, rated 10 A at 250 V.
