• About SMC Series

Introduction

SMC connectors are designed with # 10-32 threads connection and can be used for frequencies up to 10 GHz. Connector pairs can be connected and secured by means of a coupling nut system. SMC connectors primarily used in telecommunications and instrumentation applications.
