Telegärtner J01008A0012 BNC Female to TNC Male Coaxial Adapter, 50 Ohm, DC-11 GHz

This Telegärtner J01008A0012 adapter bridges BNC and TNC interfaces, enabling reliable signal transfer in RF systems where these connector types must interconnect. Its straight body configuration and precision-machined contacts ensure consistent performance across a wide frequency range.

Highlights

• BNC jack (female) to TNC plug (male) configuration
• 50 Ohm impedance for standard RF applications
• Wide frequency range: DC to 11 GHz
• Low VSWR: ≤1.25 up to 4 GHz, ≤1.5 up to 11 GHz
• Durable construction with nickel-plated brass body and gold-plated beryllium copper center contact
• Operating temperature from -55 °C to +155 °C

In daily use

Install the adapter between a BNC jack and a TNC plug to convert the connector type without altering the cable assembly. The PTFE insulator and robust plating support stable impedance and low loss, making it suitable for laboratory, test, and communication setups where frequent mating is expected.
