TELEGÄRTNER J01251A0021 BNC-liitäntä PCB-asennukseen, suora, 50 ohm

The TELEGÄRTNER J01251A0021 is a precision BNC female jack designed for direct PCB mounting, offering a straight orientation and a solid 50-ohm impedance match for reliable RF connections up to 4 GHz. Unlike typical panel-mount or cable-terminated BNC connectors, this jack is engineered for automated assembly and high-volume production, with solder pins that ensure secure mechanical and electrical bonding to the circuit board.

Highlights

• BNC female (jack) connector for PCB mounting
• Straight orientation with solder termination
• 50 Ohm impedance, DC to 4 GHz frequency range
• Gold-plated center contact and nickel-plated brass body
• PTFE insulator for high-temperature stability
• 500 V RMS voltage rating, 1500 V RMS dielectric withstanding
• Low contact resistance: ≤ 1.5 mΩ center, ≤ 1.0 mΩ outer
• Operating temperature -55°C to +155°C

In daily use

This BNC jack is ideal for RF modules, test equipment, and communication devices where a board-mounted connector is required. Its robust construction and gold plating ensure long-term reliability and minimal signal loss, even in demanding environments. The PTFE insulator provides excellent dielectric properties and withstands soldering temperatures, making it suitable for lead-free reflow processes.
