With all 12 positions loaded, the total power budget across the connector is 36 A — the derating curve in the XH series datasheet shows the safe operating window above 85°C ambient. ## Pitch, Shrouding, and Mating Half Pitch is 2.50mm (0.098\") — this is the center-to-center spacing between adjacent pins. It matches the XH receptacle series (e.g., XHP-12, B12B-XH-A) and the crimp terminals (SXH-001T-P0.6). If your board layout uses a different pitch, this header will not align. Shrouded 4-wall construction means the header body extends above and around the pins, forming a protective box. This prevents the pins from being bent during handling and ensures the mating receptacle is guided into position before the contacts engage — critical for a 12-position connector where misalignment can damage multiple pins at once. The mating half is a JST XH series receptacle housing (e.g., XHP-12) loaded with SXH-001T-P0.6 crimp terminals.","metaTitle":"S12B-XH-A(LF)(SN) JST XH Header 12 Pos Right Angle 2.5mm","metaDescription":"JST XH series 12-position right-angle header, 2.50mm pitch, shrouded 4-wall, 3A/250V, UL94 V-0, RoHS.
