A varistor is a passive, two-terminal semiconductor device used for eliminating the voltage spikes in AC voltage. It protects electrical and electronic devices from overvoltage transients via voltage clapping. Varistors can automatically change their resistance value with the change in voltage across them.

Digital isolators are used in a variety of applications to isolate digital signals by use of CMOS and similar components. Used in high-speed multichannel circuits, serial interfaces, and logic analyzer applications, digital isolators play an essential role in signal transduction. In this blog, we will discuss the basics of digital isolators while describing their importance in high-caliber circuitry.

Capacitors are a common type of electrical component that may be found in countless circuits, capable of retaining electrical energy within an electric field. As passive components that come in a wide variety of types, it is imperative that one is familiar with the particular capacitor variations that they need for a particular application. Film capacitors are one of the most common types, featuring non-polarized operations, high versatility, and low cost. In this blog, we will discuss film capacitors, their functionality, and applications, allowing you to determine whether or not they will be a good fit for your particular needs.
