CW252016-R47J Fixed Inductor

Fixed inductors are used in many electronic circuits for a variety of purposes, such as for energy storage or filtering. CW252016-R47J is a type of fixed inductor, and its application field and working principle will be discussed in this article.

Application Field

CW252016-R47J fixed inductors are commonly used for filters in radio frequency (RF) or broadband frequency protection circuits. CW252016-R47J fixed inductors are also used in powerline protection circuits, especially for EMC (Electromagnetic Compatibility) approaches.

CW252016-R47J fixed inductors are often used in automotive power module and power supply systems, as well as for RF power amplifier protective circuits in cellular phone. Additionally, the inductors are often found in battery charging, LED lighting, and computer and electronics system protection circuits.

Working Principle

Fixed inductors are constructed with wire wrapped around a solid core material with a continuous coil winding. The core material used is typically a ferrimagnetic material, such as iron. The passing of an electric current through the wire produces a magnetic field that is proportional to the current magnitude. The inductance of the inductor is determined by the area of the coil and the length of wire used in its construction, along with the relative permeability of the core material.

When an AC current passes through the inductor, an electromagnetic field is generated around the coil which creates an opposing voltage that is opposed to the applied voltage. This effect is quantified by Ohm\'s law, V = L x di/dt, where V is the induced voltage, L is the inductance, di is the change of current flowing through the inductor, and dt is the change of time.

CW252016-R47J fixed inductors have an inductance that ranges from 0.1µH to 220µH, and its rated current ranges from 0.4A to 11.7A depending on its construction and size. The self-resonant frequency of a CW252016-R47J fixed inductor is typically greater than 300MHz, so it is suitable for use in high frequency circuits. It also has low DC resistance, making it ideal for use in low loss circuits.

Conclusion

CW252016-R47J fixed inductors are versatile components with a wide range of applications. It has a high inductance, low DC resistance, and good self-resonant frequency, making it suitable for use in many RF or powerline protection circuits, as well as other circuits which require an inductor. With its various characteristics, CW252016-R47J fixed inductors are an ideal choice for a wide range of electronic circuit designs.
