The operating temperature range spans -65°C to 130°C, covering most industrial and automotive environments without derating at the low end. The post finish is tin as well, compatible with standard solder processes. ## Mounting and Mechanical Details Through-hole termination with a 0.130\" (3.30mm) post length — the solder tail protrudes below the board for wave or hand soldering. Insulation height is 0.100\" (2.54mm), keeping the profile low for tight board-to-board stacking.","metaTitle":"93944-424HLF BERGSTIK II Header, 24 Pos, 2.54mm Pitch","metaDescription":"Amphenol ICC (FCI) BERGSTIK® II 24-position single-row unshrouded header, 0.100\" pitch, 3A, tin plating, UL94 V-0.
