SMB Straight Solder / Solder Plug

32-014-D3-HC

SMB 50 ohm straight direct solder plug for semi-rigid cable. The contact is soldered to the centre conductor and the gold plated body is soldered directly to the copper jacket of the cable. Suitable for use with RG401 (0.250") semi-rigid or similar cables in group HC.

SMB 50 ohm sub-miniature series are a widely used general purpose RF connector meeting IEC 60169-10.  Smaller than SMA they feature a snap together coupling and are suitable for applications up to 4 GHz.  SMB have a gold plated centre and outer contact and are suited to applications in all industries.  In common with the similar screw coupled SMC series, the centre contacts of SMB are reversed when compared with the larger SMA, with the plug having the female contact.
