Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors play a significant role in numerous electronic devices, either to filter the DC component from an input AC signal, or to store and release energy in an electrical circuit. In this article, we discuss the 860160473012 application field and working principle and explain how they work.

Variable Capacitors

The 860160473012 is a type of variable capacitor. Variable capacitors are electrostatic devices with circular plates separated by an insulator, usually air in variable capacitors. The insulator can be air, mica or other dielectric materials. As the insulator has a variable capacitance, the capacitance automatically and continuously changes with the applied voltage or current.

When a variable voltage or current is applied across the variable capacitor plates, the dielectric material between the plates contracts, reducing the capacitor’s effective area and increasing the capacitance. When the voltage or current is removed, the dielectric material expands, increasing the capacitor’s effective area, thus reducing the capacitance. A variable capacitance is an important component in many electronic devices, and is used to modify frequency or tuning selections, threshold levels and other parameters.

Application Fields

Variable capacitors are used in many electronic applications, including radio receivers, RF amplifiers, electronic circuits, and frequency modulation synthesizers. Variable capacitors are also used in voltage regulators, audio amplifiers, power supplies and motor speed controllers.

The 860160473012 is a type of variable capacitor used in small antenna tuners. It is small enough to fit into most antenna tuners, and its low internal resistance allows high-frequency signals to pass through it. It is used to adjust the frequency or tuning of an antenna, enabling the user to adjust the antenna to the desired frequency. It is very sensitive, allowing for precise tuning.

Working Principle

The 860160473012 works based on the principle of electrostatic capacitance. It has two plates: a metal plate and a dielectric plate. The metal plate carries the voltage across the capacitor, and the dielectric plate protects the metal plate from the current. When a voltage is applied to the capacitor, electrons are drawn to the metal plate and create an electric field. This electric field causes the dielectric material to contract, increasing the amount of capacitance and allowing more current to flow through the capacitor.

When the voltage is removed, the dielectric plate expands and the capacitance decreases, reducing the current flow. This variation in capacitance, or tuning, is what makes the 860160473012 a variable capacitor. It is used in many electronic applications to control the frequency of a circuit, or to control the amount of current that flows through a circuit.

Conclusion

The 860160473012 variable capacitor is a popular choice in many applications due to its small size, low internal resistance, and high tuning sensitivity. It is used to adjust the frequency or tuning of an antenna and other electronic devices, including radio receivers, RF amplifiers, electronic circuits, voltage regulators, frequency modulation synthesizers, power supplies, and motor speed controllers.
