SMB Type RF Connectors

Please note that you only need to register as a member for the first time.

Our SMB (Subminiature Type B) type rf connectors have an impedance of 50Ω with a snap-on coupling method. Mainly used in internal devices, PCBs, board to board mounting. These connectors have a good performance up to 4GHz, provides a quick and reliable connection for high density applications.

Some SMB type RF connectors are available for purchase from Digi-Key.

No cables with SMB connectors are available in stock.

Trivia: About Cables

JIS Standard
Japanese Industrial Standards (JIS) compliant cables. The higher the number of the part number, the thicker the cable. "D: 50Ω" and "C: 75Ω" represent the impedance.
MIL Standard
Compliant with US military standards for cables. Begins with the initials "RG" and is also called Mil-Spec.
Micro Coaxial Cables
Micro coaxial cables for attaching to miniature RF connectors such as U.FL.
Semi-flexible
Shape memory coaxial cables can be bent to a certain degree but have high shielding and low loss (attenuation).
Not applicable to the SMB connector lineup.
Semi-rigid
Coaxial cables with higher shielding and less attenuation than semi-flexible cables using a seamless metal tube.
Not applicable to the SMB connector lineup.

Since these connectors are even smaller than SMA connectors, they enable high-density connections in a small space for wiring in equipment and for mounting between subassemblies and devices that make up the equipment.

Compared to the threaded coupling method, the snap-on coupling method makes coupling easier between connectors. Since connectors can be connected by simply snapping them together, it is suitable for uses in applications where space is limited.

We have a lineup of products that can be used in the high-frequency band from DC to 4 GHz.
