The 2.50mm pitch is wide enough for easy hand-soldering or wave-solder assembly, yet tight enough for compact layouts. ## Lifecycle and sourcing posture Sourced per RFQ against your BOM quantity. ## How the B4B-EH-A compares to its siblings If your BOM calls for a different circuit count, the same footprint rules apply across the series.","metaTitle":"JST B4B-EH-A Header 4 Position 2.5mm Pitch Friction Lock","metaDescription":"JST B4B-EH-A 4-position header, 2.50mm pitch, friction lock, 3A/250V, through-hole, shrouded.
