Coax Cable Capacitance Calculator

A coax is a common transmission line construction and most rf cables are coax.

Coax cable capacitance 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. Coax cable impedance calculator. C shunt capacitance 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.

This will also provide the time delay the cable provides for a signal and also the capacitance and inductance per unit length. Rf coax cable assembly designer. Most viewed companies megaphase llc. Just input the required values in the below calculator to determine the values of coaxial cable impedance cutoff frequency capacitance inductance and velocity of propagation.

Let w is the width of the trace of a microstrip and h. Actual measured values may vary from the calculated values based on manufacturing tolerances cable assembly length connector performance actual operating frequency and measurement accuracy. 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. The impedance of the coax is a relationship of the capacitance per unit length and the inductance per unit length.

Given here is an online coaxial cable impedance calculator to calculate the impedance of the coaxial cable in a circuit in terms of ohms. You can choose the measurement unit for both the inner conductor and outer conductor. L series inductance per unit length. Bookmark or favorite this coaxial cable impedance calculator page by pressing ctrl d.

The calculator will only return data for frequencies below the cutoff frequency or fco of the cable. This calculator helps you calculate the characteristic impedance of a coaxial cable given its dimensions. The inductance of a coax cable can be useful.
