dielectric constant

Working on a Wells Gardner k7500 monitor and ran across a ceramic Disc Capacitor that needs replacing. I have parts chassis that I pulled a replacement, but I'll need to rebuild the donor chassis at some point. What is being used now to replace these disc capacitors? For example, the...

In one of the article of "All About Circuits" about capacitance and inductance of twisted pair cable i found a set of formulae for computing capacitance and inductance of twisted pair cable based on diameter , spacing and dielectric constant as seen in the snapshot.. Can anybody give me the...

Hi all I need a clarification that i have designed a PCB board which has 4 layers, and no components has only holes with supply and ground. My board has failed in dielectric test. 1) How much time i can test my board for dielectric test.(1,2,times..infinity??) 2) my conductors are so close...

Hi, am facing a strange issue. In brief, the objective is to measure di-electric constant of a varnish film (approx 30micron) applied to a copper plate. To achieve this, i have made a capacitance meter (using a CC Bridge method) where the electrodes are two brass plates of 11cm diameter, between...

In this semester I have to design and make a cylindrical resonant cavity working at 4GHz to determine the dielectric constant of a small ball which would be positioned into the cavity. This resonant will be connected to a network analyzer. What dimension should I design and which modes should I use?
