Fixed Inductors are a category of electric components that feature stationary coil structures with a series of windings that are designed to curb the level of current flow in an electrical circuit. The 70F101AF is a type of axial leaded iron-core fixed inductor specifically designed for power applications requiring high inductance levels in a small package.

Basic Structure

The basic structure of a 70F101AF fixed inductor is comprised of a magnetic core produced from a ferrite material, a thin copper or aluminum coil winding, and two external leads. The core is an important component that helps expand the inductance properties and provides a high level of insulation between the coil and the leads. The coil winding consists of an assembly of tightly wound copper or aluminum wires. The leads, connected to either end of the coil in the center, provide the means for the device to be connected to the circuit.

Working Principle

The inductance operating principle of a 70F101AF Fixed Inductor is founded upon the concept of Faraday\'s Law of Induction. A voltage is applied to the coil winding, resulting in the generation of a magnetic field within the core. The induced electric current flows in the opposite direction of the applied voltage and current, creating a reverse current known as a counter electromotive force, or electromotive back electromotive force. Upon increasing the applied voltage, the induced current reaches a point of saturation, thus limiting the expansion of the magnetic field. The resulting inductance from the saturated magnetic field is then measured as a function of the voltage, current, and frequency.

Application Fields

The 70F101AF Fixed Inductor is widely used in power applications due to its high inductance levels and small package size. Its superior electrical properties make it suitable for use in a variety of switching and power supply applications. These include DC-DC converters, flyback converters, resonant converters, off-line converters, and motor control circuits. Its characteristics make it particularly useful for power conditioning applications where large quantities of current must be transferred with minimal power losses.

The 70F101AF Fixed Inductor is also used in radio frequency (RF) based signals such as television, cellular, and satellite television signals. By controlling the output of these signals, it is possible to optimize the signal reception and transmission of information.

Advantages & Disadvantages

The advantages of the 70F101AF Fixed Inductor are that it offers a high level of power efficiency, excellent inductance levels, and a small package size. Additionally, it is easily modified to meet specific power requirements. The main disadvantage of the 70F101AF Fixed Inductor is that it has a limited frequency range, making it unsuitable for use with signals with a wide range of frequencies.

Conclusion

The 70F101AF Fixed Inductor is a type of power component that is designed for use in switching and power supply applications. It offers a high level of inductance, and is conveniently packaged in a small size. Its excellent electrical properties make it a preferred choice for controlling large quantities of current with minimal power losses. It is also used in applications that require RF based signals, such as television, cellular, and satellite television signals. The 70F101AF Fixed Inductor is a great choice for power applications.
