Gold mating finish at 3.94 µinch (0.100 µm) thickness — a flash grade that provides corrosion resistance for moderate mating cycles (50–100 cycles typical) in controlled environments. For higher cycle life or corrosive atmospheres, the 8.00 µinch gold option on the 1376779-2 peer is a better fit. ## Peer Comparison: 1376779-2 vs 2355045-4 The 8.00 µinch gold supports more mating cycles — a meaningful upgrade for field-service or repeated disconnect applications.","metaTitle":"2355045-4 TE AMPMODU Header, 4 Pos, 2.00 mm, Gold, Active","metaDescription":"2355045-4 TE AMPMODU unshrouded breakaway header, 4 circuits, 2.00 mm pitch, gold mating finish, 2 A, 125 VAC/DC.
