Coax Cable Capacitance Calculator

Let w is the width of the trace of a microstrip and h.

Coax cable capacitance calculator.

Outer radius m 0 200 inner radius m 0 150 permittivity 2 3 permeability 1 capacitance per unit length farad m 4 44e 10 inductance per unit length henry m 5 75e 8 coaxial cable capacitance and inductance formula equation. This tool will help you find the inductance for a given length of coax cable. This will also provide the time delay the cable provides for a signal and also the capacitance and inductance per unit length. Most professional engineers and technicians will never have the need to calculate the capacitance inductance or impedance of a coaxial cable since they are usually designing systems using well defined components that are manufactured to exacting specifications.

Coaxial cable calculator this coaxial cable calculator determines the distributed capacitance and inductance of a coaxial cable its impedance and cutoff frequency for a given cable geometry and relative permittivity or velocity factor. Rf coax cable assembly designer. L series inductance per unit length. A coax is a common transmission line construction and most rf cables are coax.

This calculator helps you calculate the characteristic impedance of a coaxial cable given its dimensions. You can choose the measurement unit for both the inner conductor and outer conductor. Fiber optic patch cable fc fc multimode duplex 50 125 µm multiflex microwave cables. 4 6 capacitance per unit length of a coaxial cable the capacitance per unit length of a coaxial cable is given by figure 4 5 the capacitance formed by a coaxial cable 4 7 capacitance per unit length of a microstrip the structure of a microstrip resembles that of a parallel plate capacitor.

Given here is an online coaxial cable impedance calculator to calculate the impedance of the coaxial cable in a circuit in terms of ohms. The inductance of a coax cable can be useful. Most viewed companies megaphase llc. Actual measured values may vary from the calculated values based on manufacturing tolerances cable assembly length connector performance actual operating frequency and measurement accuracy.

The calculator will only return data for frequencies below the cutoff frequency or fco of the cable. The impedance of the coax is a relationship of the capacitance per unit length and the inductance per unit length. Coax cable impedance calculator. Pasternack s coaxial cable impedance calculator allows you to enter the outer diameter dielectric width inner conductor diameter width and either the dielectric constant or velocity of propagation vop values in order to calculate the impedance of the coax.
