They are widely used for television equipment connections. This connector interface was developed by Eric E Winston of Jerrold Electronics, a US company that was developing equipment for the US cable TV market, in the 1950s.

Electrical Characteristics of F-type Connectors:

  • Frequency Range: DC to 4 GHz
  • Impedance: 75 Ohms
  • Interface Standard: IEC 60169-24
  • RF Leakage: -100dB min @ 1 GHz
  • Return Loss: = ≥ 20 dB 
  • Operating Temperature: -40°C to +85°C
  • Coupling Mechanism:  Screw-on coupling
  • Mating: 3/8-32 threaded
  • Mating Cycles: ≥ 500
