Welcome to the Capacitor Fundamentals Series, where we teach you about the ins and outs of capacitors – their properties, product classifications, test standards, and use cases – in order to help you make informed decisions about multilayer ceramic capacitors (MLCCs), single layer ceramic capacitors (SLCs), and trimmers. At Knowles Precision Devices, our expertise in capacitor technology has helped developers working on some of the world’s most demanding applications, such as medical devices, military and aerospace, telecommunications, automotive, and many more. 

 Capacitor Fundamentals Blog Series-3

Part 1 – What is a Capacitor? 

This first blog post in the fundamental series discusses the key principles of capacitance and how a basic capacitor works. This blog covers topics including the key principles of capacitance, what a capacitor is, and how a basic capacitor works. 


Part 2 – How are Capacitors Used?

Capacitor technology covers a wide range of product types, based on a multitude of dielectric materials and physical configurations. This blog showcases the most common use cases for capacitors and how they can apply to your specific projects.


Part 3 – Factors Affecting Capacitance

For any given voltage, the capacitance value of the single plate device can be calculated from the geometry and dielectric constant of the device. Learn more about factors that impact capacitance in this post.


Part 4 –Dielectric Polarization

When an electric field is applied to a capacitor, the dielectric material (or electric insulator) become polarized, such that the negative charges in the material orient themselves toward the positive electrode and the positive charges shift toward the negative electrode.
