Würth Elektronik WR-SMB Subminiature Connectors are suitable for applications up to 4GHz and designed with a snap-on coupling feature. The WR-SMB series is smaller than the SMA series and ideally suited for circuit miniaturization. They are designed for transmission rates up to 40GHz at 50Ω, including versions with different insertion and retention forces. A large range of SMB connectors are offered, including PCB receptacles from THT, SMT, to edge cards and cable connectors for plugs and jacks. Jacks are primarily available for rear-mounted bulkhead mounting features.
