Data cables - electrical characteristics

In the following overview you will find information on the capacitance of data cables or shielded data cables depending on the insulation material used (wire insulation).

The capacitance values given are to be regarded as guide values. Capacities depend on the cable construction, shielding and wall thickness of the insulating sheaths and may therefore deviate from the above values.
