5-102523-1 is a single-row right-angle (SR RA) header from the AMPMODU .025 [0.64] Square Interconnection System, designed for reliable PCB-to-PCB or wire-to-board connections. This 3-position header features a 0.100" (2.54 mm) centerline pitch with 0.025" (0.64 mm) square posts and Plating C configuration consisting of tin over nickel plating. The header has overall dimensions of A = 0.420" (10.67 mm), B = 0.340" (8.64 mm), and C = 0.200" (5.08 mm). It is designed for use with 0.055" (1.40 mm) minimum thick PC boards and mates with AMPMODU wire-applied receptacles and MTE receptacles. This RoHS-compliant component is suitable for general-purpose interconnection applications requiring compact, right-angle mounting configurations.
