Termination is press-fit and solder through-hole — the press-fit tail provides a gas-tight connection before reflow, and the 0.118\" (3.00mm) post length gives a standard solder joint depth. Note that this part is listed as RoHS non-compliant; confirm your application's exemption requirements before committing.","metaTitle":"B12B-XASK-1-A JST XA Header 12 Pos 2.5mm Locking Ramp","metaDescription":"JST XA series B12B-XASK-1-A header: 12-position, single-row, 2.50mm pitch, shrouded, locking ramp, 3A/250V.
