Mutual capacitance (typ.) 23.0 pF/ft nominal
Time delay (typ.) 1.55 ns/ft nominal
Conductor DC resistance (typ.) 0.099 Ohms/ft nominal @ 20 °C

 

Digital Twisted Pairs (30 AWG)

Differential impedance (typ.) 107 Ohms @ TDR
Mutual capacitance (typ.) 14.5 pF/ft nominal
Time delay (typ.) 1.55 ns/ft nominal
Conductor DC resistance (typ.) 0.099 Ohms/ft nominal @ 20 °C

 

Digital Single Conductors (30 AWG)

Conductor DC resistance (typ.) 0.099 Ohms/ft nominal @ 20 °C

 

+5 V Lines (26 AWG)

Conductor DC resistance (typ.) 0.040 Ohms/ft nominal @ 20 °C
