SAMTEC ST420100LDPTR High-Speed Micro Connector

The ST4 series contact is a super-low profile connector designed for space-saving on-board applications, featuring a narrow body and 4mm stack height. It uses black LCP insulators and phosphor bronze contacts plated with Au or Sn over Ni for durability and reliable performance. With a current rating of 1.6 A per pin, it supports high-speed differential signaling up to 31 Gbps. Suitable for SMT mounting with coplanarity of 0.10 mm, it is compliant with industry standards and offers robust insertion force and low PCB effects, ideal for high-density electronic assemblies.
