Product Overview

TNC Series RF Connector

Aptiv Interconnect's TNC and TNCA series threaded coaxial RF connectors provide a robust and reliable alternative to BNC connectors, offering enhanced performance in demanding environments. These connectors deliver exceptional performance at higher frequencies, typically up to 11 GHz (with precision versions reaching 18 GHz), and in applications subject to high vibration or shock. The TNC's threaded coupling ensures a secure, vibration-proof connection with superior electrical stability. Its rugged construction and excellent electrical characteristics make it an ideal choice for military, aerospace, industrial, and telecommunications applications where unwavering reliability is critical.
