Introduction to Fixed Inductors

Fixed inductors are electrical components that use one or more turns of wire, a magnetic core, and a dielectric insulation within the coil to store electrical energy in magnetic fields. They are used to “shunt” or divert current, creating a path for it to travel, and for Radio Frequency (RF) energy attenuation. By virtue of their stable performance, they are extremely versatile and used in a variety of applications.

Applications of Fixed Inductors

Fixed inductors can be found in a variety of applications. In the automotive industry, they are used to help filter and route electricity, reduce emissions, and improve performance. They are also prevalent in the military and aerospace industries, where their ability to filter harmonics has enabled them to be used in avionics and navigation systems. Home appliances, consumer electronics, computers, and many industrial processes also rely upon fixed inductors to enable their function.

The 70F827AP Fixed Inductor

The 70F827AP is a surface-mount fixed inductor, designed to meet the requirements of automotive, industrial, and military applications. It is manufactured from a nickel-iron base material, and is suitable for production serving temperatures from -55 to +125 degrees Celsius. This device has low DCR and low Core loss, resulting in higher efficiency and low power consumption.

70F827AP Application Field and Working Principle

The 70F827AP fixed inductor is ideal for use in automotive and industrial applications, such as filtering, coupling, RF energy attenuation, and snubbing. Its low DCR and low core loss make it suitable for high-efficiency applications such as power supplies, DC/DC converters, and phase control circuits.The working principle of the 70F827AP fixed inductor is simple. An electric current is passed through the coil, creating an alternating magnetic field. The changing magnetic field creates a voltage in the windings, which in turn creates a magnetic field. This changing magnetic field induces a voltage in a second winding, creating a current. This current is then used to produce a stable, resistive output voltage. As the current passes through the coil, energy is stored in the form of magnetic field. When the current is shut off, the energy stored in the form of a magnetic field is released, producing a resistive output voltage.

Conclusion

The 70F827AP fixed inductor is a high-efficiency component that can be used in a variety of automotive, military, and industrial applications that require a stable resistive output voltage. Its low DCR and low core loss enable it to be used in applications with higher efficiency and lower power consumption. With its ability to filter harmonics, it is a great choice for avionics and navigation systems.
