Data Cables - Electrical Characteristics

The following overview provides information on the capacitance of data cables and shielded data cables based on the type of insulation material used for wire insulation.

The capacitance values listed serve as general reference points. Actual capacitance may vary depending on factors such as cable construction, shielding, and the wall thickness of the insulating layers. Therefore, slight deviations from the stated values are possible.

The mentioned values are approximate values. Capacitance is dependent on cable constructions, screenings and wall thickness of the insulation and, therefore, can be different from above mentioned data.
