SMB female connection on breadboard
The pins as described, squares pins of 0.03&quot; seems too big for a standard breadboard. It may not fit in the plastic holes and if it does it will probably stretch out the spring leafs of the connectors. It is bigger than the average 0.025&quot; or smaller standard headers, and breadboards are more suited for round pins. The center pin seems like its the same size but might be bigger.
The rest seems like it would fit, based on center to center spacing, taking up a 9 x 9 square of breadboard holes.
If you really need a smb connector you are better off using a pigtail to a standard header or breakout board. As breadboard have high capaticence and noisy for most RF or high speed signal purposes, you might as well make it easy to plug in without damaging the board and having to troubleshoot bad connections.
