| SMC SERIES- SubMinature version C Coaxial Connector |
| |
| 1. |
Developed in the 1960s. It has same interface dimension as SMB connector, but SMC has thread mating design. |
| |
| 2. |
SMC connectors are designed originally with female contact in male body or male contact in female body. |
| |
| 3. |
SMC connector especially is suitable for mobile applications with low VSWR. |
| |
| 4. |
They use a #10-32 UNF threaded interface (screw type) and are available in 50 Ω or 75 Ω impedances. |
| |
| 5. |
They offer excellent electrical performance from DC to 10 GHz. |
