Terminal loads
In order to avoid reflections at the ends of transmission media, these must be terminated with its characteristic impedance. This component is called terminator load.
A terminator is the impedance of the transmission medium and ensures that no reflections occur at the cable end.
Here you find 50 Ohm terminators of the SMA / R-SMA series, SMC series, BNC series, TNC series, N series and of the 7-16 series.
