1903121-1

TE Connectivity AMP Connectors's 1903121-1 sets new standards in Rectangular Connectors - Contacts technology, specifically developed for mission-critical connectivity solutions. Its innovative design addresses common challenges in high-speed digital systems while ensuring long-term reliability.The Stamped manufacturing process produces contacts with exceptional dimensional stability across temperature variations. This attribute is essential for automotive applications experiencing -40 C to 125 C operating ranges.The Tab interface configuration offers exceptional EMI shielding properties, making it ideal for sensitive measurement equipment. This design characteristic significantly reduces crosstalk in multi-channel applications.Engineered with Crimp technology, these contacts provide gas-tight connections that prevent oxidation buildup. This termination style is particularly beneficial in aerospace applications where environmental sealing is crucial.Supporting 22-28 AWG conductors, the contact system balances current capacity with space efficiency. The optimized contact geometry prevents wire deformation during installation while ensuring consistent contact pressure.The Tin plating delivers exceptional wear characteristics, rated for over 10,000 mating cycles. This finish selection is based on extensive testing for fretting corrosion resistance in humid environments.
