0805-56NJ

Fixed inductors are electric components that either store electrical energy in the form of a magnetic field or convert electrical energy into magnetic field energy. Generally, inductors consist of one or more winding coils made from copper, aluminum, or other suitable metal wire, and surrounded by an insulating medium. The 0805-56NJ inductor is a fixed-core chip inductor used in a variety of applications, making it ideal for use in modern electrical designs. This article looks at the features and applications of 0805-56NJ and discusses its working principle.

Features and applications

The 0805-56NJ is a chip-shaped ceramic air core inductor with an inductance range of 10 nH to 56 nH. Its surface mount design allows for easy installation, while its compact size allows it to be used in small spaces. It has an operating temperature range of -40°C to 125°C, making it suitable for industrial environments. The 0805-56NJ also offers good DC superposition characteristics, meaning that it can handle high currents without being damaged.

Due to these features, the 0805-56NJ is commonly used in a wide range of electronic applications, such as radio frequency (RF) circuits, switching power supplies, and automotive electronics, as well as power line filters, pulse amplifiers, and transformers. It is also commonly used in fields such as telecommunications, medical devices, consumer electronics, and automotive electronics.

Working principle

The 0805-56NJ’s working principle is based on the concept of mutual inductance. Mutual inductance is a property of two coils where an electrical current in one coil induces a voltage in the other. This phenomenon is known as electromagnetic induction.

When an alternating current (AC) is applied to the 0805-56NJ, the magnetic field’s intensity in the coil increases or decreases. This induces a current in the core material, which is then changed into an electrostatic field and sent back through the coil as an induced current. This induced current has a frequency and amplitude that depends on the number of windings and the rate of change of the current in the inductor.

The 0805-56NJ also has a fixed core, which is made up of ferrite and other ceramic materials. These materials enable the inductor to better handle higher temperatures, and they significantly reduce losses due to eddy current caused by high operating frequencies.

Conclusion

The 0805-56NJ fixed inductor is a versatile and reliable component that is suitable for a variety of industrial and consumer applications. Its small size and operating temperature range make it well-suited for use in modern electrical designs, while its operating principle allows it to handle high-frequency currents without experiencing significant losses.
