Introduction to Fixed Inductors

Fixed inductors are a type of passive component used to store energy in an electromagnetic field. They are widely used in electrical circuits for numerous applications, ranging from basic power supplies to complex electronics used in aerospace technology. Generally, fixed inductors work by generating a magnetic field when electric current flows through them. This magnetic field allows the inductor to store and provide energy to circuits. The two most common types of fixed inductors are air-cored, which use a hollow core to store and transfer energy, and ferromagnetic cored, which use a ferromagnet to store and transfer energy.

70F221AF Application Field

The 70F221AF fixed inductor is one of the most frequently used inductors for components in modern electrical engineering, and is mostly used in various applications in the automotive industry. It is primarily used for PWM (pulse width modulation) and power filter that requires frequency response with high efficiency and fast switching. It is also used for a wide variety of high-performance applications such as appliance, solar, and LED lighting.

Working Principle of 70F221AF

The working principle of the 70F221AF fixed inductor is based on the principle of inductance, in which an electric current flowing through a conductor creates a magnetic field. The 70F221AF inductor is composed of a conductor (most commonly a coil of wire) encased in a sealed magnetic core material that provides additional inductance. When current flows through the inductor, it produces a magnetic flux that is contained by the core material and transfers energy back to the circuit.

Conclusion

In conclusion, fixed inductors are a type of passive component used to store energy in an electromagnetic field. The 70F221AF is a popular fixed inductor that is used in a number of automotive and high-performance applications. It works by creating a magnetic field when electric current is applied, allowing the inductor to store and transfer energy back to the circuit.
