BNC Terminators

BNC terminators provide reliable 50-ohm or 75-ohm termination for coaxial systems using BNC connectors. Ideal for low to mid-frequency RF applications, they are commonly used in test setups, broadcast systems, and network equipment to eliminate signal reflections and maintain transmission line integrity.

A BNC terminator is used to close the end of a BNC-terminated coaxial line to prevent signal reflection. This helps stabilize signals in RF and video systems, especially when unused ports or test points need proper impedance matching to avoid signal degradation.

BNC terminators are commonly available in 50-ohm and 75-ohm versions. The 50-ohm type is used in RF and data systems, while the 75-ohm version is preferred for video and broadcast applications. Choosing the correct impedance is essential for optimal signal performance.

BNC terminators typically support frequencies up to 4 GHz for 50-ohm types and up to 2 GHz for 75-ohm types, depending on the construction quality. They are suitable for most general-purpose RF, data, and video signal termination needs.

BNC terminators are widely used in test and measurement instruments, analog and digital video systems, RF communications, and Ethernet (10BASE2) networks. They are essential for unused BNC ports or open-ended lines to ensure proper impedance matching and minimize interference.

It’s not recommended. Using mismatched impedance (e.g., 50-ohm terminator on a 75-ohm line) can cause signal reflections, loss, and distortion. Always match the terminator’s impedance to your system’s characteristic impedance for optimal performance and signal integrity.
