Fixed Inductors: CIL21NR82KNE Application Field and Working Principle

Fixed inductors are passive electrical components which help in connecting circuits in electronic systems. Their main use is to create magnetic fields, and they can be used in a variety of applications such as amplifiers, RF devices, impedance matching networks, signal isolators, and other similar applications. In particular, the CIL21NR82KNE fixed inductor has a number of features and a wide range of uses, as discussed below.

Application fields

The CIL21NR82KNE fixed inductor can be used in a variety of applications, including:

• In RF and microwave circuits for impedance matching, filter tuning, and other applications
• In audio power amplifiers
• In impedance matching networks and signal isolators
• In mobile phones for use in isolation transceivers
• In analog and digital filters
• In DC-DC converters for providing power isolation

The inductor\'s small size and high power rating make it ideal for use in these applications.

Working Principle

Fixed inductors are designed to create magnetic fields and store energy within them. When an electric current flows through the inductor\'s windings, the current will be generated due to a change in the inductor\'s magnetic field. This generated electric current will oppose the original current, causing the inductor\'s electrical resistance to increase.

In addition, as the inductor\'s current is changed, the magnetic field it produces will also change. This change in the magnetic field will generate an opposing voltage across the inductor, due to Faraday\'s Law. This opposing voltage is known as Back EMF (electromotive force).

Finally, when the inductor\'s current is changed rapidly, the varying magnetic field will induce an electromagnetic torque in the inductor\'s windings, which can cause the inductor to vibrate. This can be useful in applications such as vibration motors.

The CIL21NR82KNE fixed inductor is designed to provide power isolation and high power ratings for a variety of applications. Its small size and relatively high power rating make it perfect for a range of uses including RF and microwave circuits, audio power amplifiers, impedance matching networks, signal isolators, and DC-DC converters.
