Inductor vs. Capacitor: What''s the Difference?
This energy can be used to help circuits work better and smoother. Capacitors have two metal plates separated by an insulator. When voltage is applied, the capacitor accumulates charge on each plate. The amount of charge that the capacitor can store is proportional to the surface area of the plates, and the distance between them.

Varistor | Resistor Types | Resistor Guide
Varistors are useful for short duration protection in case of high transient voltage surges in the order of 1-1000 microseconds. They are however not suitable for handling sustained surges. If the transient pulse energy, measured in joules (J), significantly exceeds the absolute maximum ratings, they can melt, burn or explode.
Varistor
Metal-oxide varistor manufactured by Siemens & Halske AG. Modern varistor schematic symbol, which is the same as a thermistor symbol [1]. A varistor (a.k.a. voltage-dependent resistor (VDR)) is a surge protecting electronic component with an electrical resistance that varies with the applied voltage. [2] It has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of ...
The Principles of Varistor Selection
The behavior of varistors in a circuit is similar to TVS diodes, but they are entirely different in design, materials, and construction. There are many kinds of varistors ... for additional EMC capacitors in the system. 2 ã ¸ ç î A varistor is an electronic component used to suppress transient voltages to protect electronic
Metal Oxide Varistors (MOVs)
Metal oxide varistors (MOVs) come in vibrant blue or orange hues and are typically round. They''re strategically placed on the AC input side of power circuits to guard against voltage surges. At their core, MOVs function by adjusting their resistance in response to voltage changes. When the voltage is stable and within normal limits, a MOV remains highly resistant, exerting minimal …

One additional feature of KEMET varistors is that some are available as dual-function devices with X7R capacitors built into the same package, thereby providing suppression and snubbing in a single package to reduce component count and enhance circuit reliability.
8.2: Capacitors and Capacitance
A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...
Circuit Protection from Transient Voltage by Varistor
Varistors are used to protect a circuit from high voltage surges. When a high voltage surge is applied to a circuit, the outcome is usually catastrophic to the circuit. A capacitor may be installed across the signal lines. However, this capacitor cannot suppress voltage surges. Therefore, when circuit protection from voltage surges is
Metal Oxide Varistors Overview and Supply Chain
Varistors are produced in two primary configurations: chip and disc. Disc varistors have been around for 50 years, while chip varistors are relatively new and have been available for about 25 years. Varistor construction methods are similar to ceramic capacitor production methods for both disc and chip versions.
