Fixed Inductors: 4470-02H Application Field and Working Principle

Fixed inductors are essential components in electricity supply systems. Electromagnetic coils are used in various electrical and electronic circuits, such as transformers, regulators, filters, oscillators, motors, relays, and wave trap circuits. The 4470-02H Fixed Inductor is a PCB assembly mounted, pressure sensitive type coil with a maximum current carrying capacity of 1.3 Amps.

Application Field

The 4470-02H is specifically designed for use in a wide range of DC applications. It can be used as a common mode inductor in power supplies, switching regulators, dc-dc converters, and flyback power supplies. This type of inductor is also ideal for applications that require high frequency switching. It is a perfect choice for digital variable speed drives, motor drives, and converters.

Working Principle

The working principle behind the 4470-02H is very simple. It is a fixed inductor, or an electrical component that induces a magnetic field when AC or DC current is applied to it. Current passes through the windings of the inductor, creating a magnetic field. The magnetic field then interacts with the current, resulting in resistance to the flow of current. This resistance, known as inductance, is measured in henries. The 4470-02H\'s unique design allows it to effectively reduce common mode noise in power supplies, switching regulators, and dc-dc converters. The inductor also provides high current handling capacity up to 1.3A, ensuring its compatibility with high power applications. Furthermore, it has an isolation voltage of 3kV, making it suitable for use in applications with high voltage requirements.

Advantages and Disadvantages

Fixed inductors such as the 4470-02H have several advantages. They are very efficient at suppressing common mode noise in power supplies, have low DC resistance, and possess high current carrying capacity. They also have the ability to handle high frequency switching, making them ideal for applications with a wide range of frequency requirements. Despite their many advantages, fixed inductors have some drawbacks as well. They tend to be expensive, and their size is often quite large compared to other types of inductors. Furthermore, since they are fixed components, they cannot be adjusted or replaced if needed.

Conclusion

The 4470-02H Fixed Inductor is an specialized component used in a range of power supply designs, motor drives, and other high power applications. As a fixed component, the 4470-02H offers high current handling capacity, good noise suppression, and high voltage isolation capabilities. However, its cost and size tend to be limitations compared to other types of inductors.
