Fixed Inductors

Fixed inductors are passive electrical components, which act as a conductive loop when electric current is introduced, creating a magnetic field which, in turn, generates electrical current. The S0402-2N2J3 fixed inductor is a small component, measuring just 0.2” in size and designed to regulate power in low-profile electronic devices.

Applications

The S0402-2N2J3 fixed inductor is typically used in cellphones, laptops, gaming consoles and other portable electronic devices, due to its small size and low profile. It is also widely employed in appliances like microwaves and washing machines, as well as in automobiles and other vehicles.

The S0402-2N2J3 can also be used in devices like power supplies, radio receivers, antennas, motor control systems, modems, and medical equipment. It was designed to provide power for low-profile electronic devices without drawing too much attention from other components.

Working Principle

To understand the working principle of the S0402-2N2J3 fixed inductor, one needs to understand how inductors work in general. An inductor is a passive electronic component that resists a change in current through it. When electric current is run through the inductor, it will generate a magnetic field, which is proportional to the electric current flowing through it. This magnetic field then creates a back electric field, which is directly opposite in direction to the electric field.

This back electric field creates an opposition, or ‘back EMF’, to the flow of the electric current. This back EMF limits the amount of current flowing through the inductor, effectively smoothing and regulating the power applied to the circuit. This is the basic principle by which all fixed inductors, including the S0402-2N2J3, operate.

Features/Characteristics

The S0402-2N2J3 fixed inductor has a few unique characteristics that set it apart from other inductors. The first is its size, which is just 0.2”. This compact size allows it to be used in low-profile electronic devices without taking up too much space. The other characteristic is its high inductance. It has an inductance value of 2.2mH, which is relatively high for a component of its size.

The S0402-2N2J3 also has a low minimum DCR, or direct current resistance. This ensures that the inductor will not create too much resistance when current is being applied. Finally, the S0402-2N2J3 has an operating temperature range of -40°C to +85°C, meaning it can handle a wide range of temperatures without any detriment to performance.

Conclusion

The S0402-2N2J3 fixed inductor is a small component designed to regulate power in low-profile electronic devices. It is commonly employed in cell phones, laptops, gaming consoles, and other portable electronic devices, as well as in larger appliances and automobiles. The S0402-2N2J3 is characterized by its small size, high inductance, low DCR, and wide operating temperature range. With the help of the S0402-2N2J3 fixed inductor, power can be effectively regulated in a variety of applications.
