Apart from the continuously variable types, preset type variable capacitors are also called trimmers. They are generally small devices that can be adjusted or "pre-set" to a particular capacitance value with the aid of a small screwdriver and are available in very small capacitance''s of 500pF or less and are non-polarized.
In electronics, a varicap diode, varactor diode, variable capacitance diode, variable reactance diode or tuning diode is a type of diode designed to exploit the voltage …
Ceramic Trimmer Capacitor Ceramic trimmer capacitors are very small and thin capacitors that include external dimensions L x W x H as 1.5 x1.7 x 0.85 mm. The construction of this capacitor is unique without using …

What is Capacitive Transducer : Working and Its Applications
A variable-capacitance diode is a type of diode that uses the capacitance characteristics of the depletion layer. The depletion layer appears in the p-n junction when a diode is reverse-biased. Its thickness increases in reverse proportion to the reverse voltage.The capacitance characteristics and the rate of change of capacitance (as a function of …

A variable capacitor is a capacitor whose capacitance can be adjusted within a certain range. When the relative effective area between the pole metal plate or the distance between the plates is …
Ceramic capacitors, electrolytic capacitors, film capacitors, tantalum capacitors, and variable capacitors are just a few examples of the types available. Understanding the characteristics and applications of each type is essential for selecting the right capacitor for a specific circuit design.
Now we will learn about the single phase motor 2 capacitor wiring diagram or capacitor start capacitor run motor. A capacitor start capacitor run motor is also known as a two value capacitor motor . The "two value" comes from the installation of two capacitors for two different purposes: start and run.
