UP2C-221-R

Fixed inductors, also known as chokes, are components used to store and release energy in current flow. They play an important role in various electronic circuits for controlling alternating current flow. UP2C-221-R is a type of fixed inductor which is composed of a series of thin metal coils to form a small, cylindrical electrical inductor. Generally speaking, it has a maximum voltage of 50V, a rated DC current of 0.73 amps, a saturation current of 1.25 amps, and a rated inductance of 221mH.

Application Field of UP2C-221-R

UP2C-221-R is most commonly used in switching power supplies, telecommunication systems, and data conversion circuits. Following are several specific application fields of UP2C-221-R:

• Telecommunication Equipment: UP2C-221-R is used in various telecom equipments such as base stations, mobile phones and PABXs.
• Air Conditioners: UP2C-221-R plays an important role in regulating and controlling the flow of current in air conditioners units.
• Solar Inverters: These inductors are also used in solar inverters to control and store energy produced from sunlight.

Working Principle of UP2C-221-R

When current is applied to a fixed inductor, such as UP2C-221-R, magnetic flux is created around a thin metal coil. This magnetic flux creates a counter-flux which resists the flow of current in the inductor. In other words, the inductor resists changes in current flow, and thus it allows controlled flow of electric current. Its rated inductance value indicates the number of coils used and the amount of resistance that is induced when current is applied.

Limitations of UP2C-221-R

Like other fixed inductors, UP2C-221-R may suffer from saturation state at high temperatures. When the temperature of the inductor reaches a certain level, it may not be able to resist changes in current flow anymore. Another limitation of UP2C-221-R is its relatively low saturation current value. This is due to its limited number of coils in the design.
