The 3821-40023 is an SMPS backplane contact specifically engineered for use with Ø.047 inch cable. This component operates with a characteristic impedance of 50 Ohms and supports a wide frequency range from DC to 40.0 GHz. The contact body is made from beryllium copper with a gold plating over nickel for superior conductivity and durability, while the main body is constructed from passivated stainless steel. It is designed for integration into VITA 67.3 backplane modules, providing a reliable high-frequency interconnect solution for demanding applications.
