It is a 50 Ohm impedance-matched connector rated to 4 GHz maximum frequency, with a specified insertion loss of 0.3 dB. The snap-on fastening type provides quick, tool-less mating typical of the SMB interface — the bayonet-style coupling engages with a push and locks with an audible click, making it suitable for applications where frequent connect/disconnect is needed. The shield termination is specified as solder, meaning the outer conductor of the coaxial cable or PCB trace is soldered directly to the connector body. The single-port design accepts a male SMB plug on the mating side. ## Voltage Rating and RF Performance The voltage rating is 335 V. At 4 GHz, the 0.3 dB insertion loss is typical for a well-matched SMB interface at this frequency — the loss is dominated by the PTFE dielectric and the gold-plated contact interface. The 50 Ohm impedance is standard for RF signal paths; confirm that the mating plug and cable assembly also maintain 50 Ohm characteristic impedance to avoid reflections.","metaTitle":"TE Connectivity 413990-3 SMB Receptacle, 50 Ohm, 4 GHz","metaDescription":"TE Connectivity 413990-3 SMB receptacle, male pin, 50 Ohm, 4 GHz max, 500 mating cycles.
