The -GU suffix specifies gold plating (16.0 µinch) versus the tin plating on the base B2B-XH-A. For applications requiring higher mating cycle endurance or better corrosion resistance, the gold variant is the correct choice. The B2B-XH-AM(LF)(SN) adds a board guide feature but retains tin plating.","metaTitle":"JST B2B-XH-A-GU Header 2 Pos 2.5mm Gold Active","metaDescription":"JST B2B-XH-A-GU XH series header, 2 positions, 2.50mm pitch, 3A, 250V, gold plating, through hole, shrouded.
