Product details

JST XA 12-Position Header with Locking Ramp

Rated at 3 A per contact and 250 V, with tin-plated male pins and a UL94 V-0 glass-filled PA66 housing, it suits moderate-power signal and power interconnects in industrial and consumer equipment.

Pitch, Positions, and Mated Stack Height

At 12 circuits, this header sits between the 10-position and 13-position variants in the XA single-row family — the B13B-XASK-1-A adds one more position while keeping the same 2.50mm pitch, 3 A rating, and locking ramp.

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.
