Fixed Inductors

A fixed inductor, or coil, is an electrical component that stores energy in the form of a magnetic field created by an electric current. It is composed of a coil of wire in which the current flow creates a magnetic field whose poles depend on the direction of the current. Often the core of the inductor is made of ferromagnetic material to enhance the magnetic field produced. The NRV3012T1R0N is one such fixed inductor.

NRV3012T1R0N Application Field and Working Principle

Broadly speaking, fixed inductors are used in a wide range of applications, including AC-DC, DC-AC, RF and microwave, switching power supplies, and high voltage converters. The NRV3012T1R0N is specifically a shielded toroidal blue SMD chip inductor, designed for high current, high frequency applications such as DC-DC converters, power supplies, and other automated control and electronic equipment.

In terms of its working principle, the NRV3012T1R0N has a core made of toroidal ferrite--a type of ferromagnetic material that helps to maximize the magnetic fields generated by an electric current. The windings are then wound around the core, and a shield (or casing) is placed over the core and windings to protect them and increase the inductance. As is typical for induction coils, the NRV3012T1R0N creates a magnetic field whenever an electric current flows through it. This magnetic field then produces an electromotive force (EMF) which opposes the flow of the current. This effect--known as Lenz\'s Law--is what makes fixed inductors useful for applications such as power supplies and DC-DC converters.

The NRV3012T1R0N is designed to be highly efficient and resistant to EMI (ElectroMotive Interference). It is rated at 1µH (+/-20%), with SRF at 1.2GHz min, Rdc 105Ω max, and Iddc 150mA max. It is also RoHS compliant and has a temperature range from -40℃ to 85℃.

Advantages of Fixed Inductors

Fixed inductors offer many advantages over other types of inductors. As mentioned above, they are capable of creating a magnetic field at very high frequencies, making them ideal for use in high frequency application such as RF and microwave components. They are also very efficient, with high inductance-to-size ratios, and are able to store energy for long periods of time. Additionally, fixed inductors are relatively inexpensive, durable, and easy to install.

Conclusion

The NRV3012T1R0N is a fixed inductor designed for high current, high frequency applications such as DC-DC converters, power supplies, and other automated control and electronic equipment. As a fixed inductor, it has the advantage of being able to generate a magnetic field at high frequencies, as well as being highly efficient, durable, and comparatively inexpensive. It is specifically designed to be resistant to EMI and has a wide temperature range, making it suitable for a variety of applications.
