Paper Capacitors

Because paper is porous it has to be impregnated in order to prevent corona effects and flash-overs. It is done by use of melted wax or different kinds of oils, among other things mineral and silicone oils. The oils increase the tensional stability but decrease to a certain extent the εr. A fibrous paper has a εr ≈ 6.6 and the mineral oil ≈ 2.3 which gives the impregnated winding a εr varying between 3.1 and 4.5. The differences depend above all on the winding pressure produced by the tensile force during winding.

MLCCs are the most common type of capacitor out there. Almost every single electronic device uses MLCCs in a multitude of applications. We all know what MLCC stands for (multilayer ceramic capacitor), but do you know how they are made? What are the different types and how to choose from among all the...

Pros and Cons of MLCC Downsizing

Posted by doEEEt Media Group
On January 25, 2021

Advantages and disadvantages of MLCC downsizing are discussed in AVX technical papers written by Frank Hodgkinson and Maureen Strawhorne. As integrated circuits (ICs) continue to pack more functionality into smaller packages, the need for bulk off-chip capacitance remains. In resonant circuits, such as phase-lock-loops (PLLs) and switching regulators, precision class one ceramic capacitor may be required.

There is a measurable correlation between the rate at which nations attempt to achieve carbon emissions goals and the rate at which they develop electric vehicles. Many of these emissions goals have been set for the year 2025, which means that a significant boost in the demand for components that enable such reductions is well underway.
