BNC

About BNC Series

BNC coaxial connectors are one of the world’s most popular RF connectors. They are miniature, light-weight and can operate satisfactorily up to 4 GHz. The BNC is typically used in applications from DC to 4 GHz and yield low reflection in this frequency range. Cable terminations are available in crimp, clamp, solder and jacket quick twist configurations. The two-stud bayonet lock coupling provides ease of connecting and disconnecting and is ideally suited for applications such as test equipment where this feature is notably significant. BNC connectors are most prevalent in computer networks, audio, data processing and telecommunications equipment because of their size and relatively low installed cost.

Applications

  • Computers/LANs
  • Instrumentation
  • Test and Measurement
  • Medical Equipment
  • Broadcast (75 ohm)

Electrical

Impedance:50Ω / 75Ω
Voltage Rating:≥500 V rms (depending on cable)
Insulation Resistance:≥5 GΩ
Dielectric Withstanding Voltage:≥1500 V rms
Contact Resistance:Center Contact ≤1.5 mΩ、Outer Contact ≤1 mΩ

Features

  • BNC connectors with a 50 ohm nominal impedance are designed for use in telecommunication, data communication and test and instrumentation equipment. BNC connectors with a 75 ohm nominal impedance are designed for broadcast, video and other applications which require impedance matched performance. Both 50 ohm and 75 ohm BNC connectors are intermateable.
  • Interface according to IEC 169-8, MIL-STD-348B
