Introduction

Fixed Inductors are one of the most important components in electronic circuits, which are used to store energy in the form of a magnetic field. They are usually composed of a coil of wire with an iron core and a housing, as well as capacitors, resistors and other components. The most commonly used Fixed Inductor is the B82422T3120K000.

B82422T3120K000 Application Field and Working Principle

The B82422T3120K000 is a fixed inductor developed by EPCOS. It is widely used in DC-DC converters, noise filters, power supplies, monitors, loudspeakers, electrical toys, LED drivers, and other electronic fields. It fmax is 2000MHz and its self-resonance frequency is 6GHz, which shows its capacitance is extremely low. The product allows a maximum operation temperature of 85℃. In terms of its working principle, the B82422T3120K000 Fixed Inductor can be regarded as a coil, and the current passing through the inductor will generate a closed magnetic field in the coil. The magnetic field strength and the amount of induced voltage will be proportional to the current magnitude, making it work as a passive electrical component which can transmit energy.

Structure and characteristics of B82422T3120K000

The B82422T3120K000 Fixed Inductor has a size of 8x2.2x1.2mm and is composed of a single-layer wound internal coil and a shield case. The insulation grade of the internal coil is class H (HR -85°C/RH-90%), and the insulation grade of the shield case is class F (FR-85°C/HR-90%). It has an excellent temperature characteristic of +10 ppm/K, and is provided with a special coating to protect it from external shocks. The maximum operating temperature is 85℃, and the insulation resistance is >100 Megohms. Its main feature is that it has a very low power loss at higher frequencies, meaning it\'s very efficient when it comes to energy storage. Additionally, it is capable of suppressing high frequency noise and improving the power factor.

Advantages and Disadvantages of the B82422T3120K000

The B82422T3120K000 Fixed Inductor has many advantages while also having some disadvantages. One of the biggest advantages of the B82422T3120K000 is its very wide operating temperature range of -55 to +85 ℃. It also has a very low power loss at higher frequencies, meaning it is very efficient when it comes to energy storage. Additionally, it is capable of suppressing high frequency noise and improving the power factor.On the other hand, the B82422T3120K000 also has some disadvantages. One of the main disadvantages is its relatively small size compared to other inductors, which means that the capacity is not as high. Furthermore, its working frequency is limited to 2000MHz, which means it cannot be used for applications requiring higher frequencies.

Conclusion

In conclusion, the B82422T3120K000 Fixed Inductor is a widely used inductor due to its size, frequency range, temperature range, power factor, and efficiency. Its wide applications include DC-DC converters, noise filters, power supplies, monitors, loudspeakers, electrical toys, LED drivers, and other electronic fields. It has many advantages such as its very wide operating temperature range of -55 to +85 ℃, very low power loss at higher frequencies, and the capability of suppressing high frequency noise and improving the power factor. However, its capacity is not as high as other inductors due to its relatively small size, and its working frequency is limited to 2000MHz. Furthermore, it has some additional disadvantages such as its high cost and short overall lifespan.
