0819R-68K

Fixed inductors are electronic devices that consist of a wire wound around a coil. Inductors can be used in many applications, including radio frequency amplifiers and signal processing circuits, and to filter, store, and regulate electrical signals. The 0819R-68K is a type of fixed inductor which is considered one of the most popular types for radio frequencies. It is an 8 pin device consisting of an enclosed coil inside a ferrite core.

Application

The 0819R-68K fixed inductor is most frequently used in radio frequency applications, such as antenna circuits, radio tuners, and amplifiers. It is also used to regulate and filter signals in sensitive electronic components, such as analog-to-digital converters, amplifiers, and A/D converters. Due to its compact size and low cost, it is also used in low-noise broadcast systems and other low frequency applications.

Working Principle

The 0819R-68K fixed inductor operates on the principle of electromagnetism. When a current passes through the device, a magnetic field is created, which is proportional to the current. The magnetic field induces a voltage in the inductor, which is inversely proportional to the current. This voltage is called the back EMF, and is used for filtering, regulation, and signal processing.

The inductance of a fixed inductor depends on the number of turns in the coil and the permeability of the core material. The number of turns determines the inductance, with more turns resulting in a higher inductance. The permeability of the core directly affects the inductance, with higher permeability resulting in higher inductance. The 0819R-68K fixed inductor features a ferrite core, which gives it high permeability and good inductance.

Conclusion

The 0819R-68K fixed inductor is one of the most popular types for radio frequency applications. It is a compact 8 pin device that consists of an enclosed coil inside a ferrite core. It operates on the principle of electromagnetism, and its inductance is dependent on the number of turns and permeability of the core material. It is frequently used in antenna circuits, radio tuners, amplifiers, and for low frequency applications due to its low cost and small size.
