3-102202-4 – TYCO ELECTRONICS

Overview

The TE Connectivity AMPMODU Mod II 3-102202-4 is a 3-position, shrouded vertical header designed for robust board-to-board or cable interconnections. Its 2.54mm pitch and gold-plated mating contacts ensure low insertion force and reliable signal integrity, critical for applications demanding consistent electrical performance. A key design consideration for this connector is managing the trade-off between the high-performance gold plating for mating surfaces and the more cost-effective tin-lead plating on the post for solder termination, which can influence long-term solder joint reliability in corrosive environments.
