Introduction to Fixed Inductors
Fixed inductors are a type of passive electronic component that are used to store energy through a magnetic field. This type of inductor typically consists of a coil of wire wrapped around a ferromagnetic core. As electric current passes through the coils, a magnetic field is created. This magnetic field then exerts a force on the electrons, causing them to accumulate in the form of a current.Fixed inductors are essential components of power supplies, radio transmitters, and other electronic applications. In order to achieve optimal performance and reliability, the design and construction of these components should adhere to a few essential criteria. First, the size and type of core material should be chosen to meet the application\'s specific requirements. Second, the magnetic field should be as uniform as possible, to avoid stressing the core material and resulting in excessive heating. Finally, the inductance value of the component should be designed to ensure the desired ringing frequency.SRP4020-R47M Application Field and Working Principle
The SRP4020-R47M is a type of fixed inductor typically used in power supply and radio transmitter applications. The size and type of core material for the SRP4020-R47M are carefully selected according to the requirements of the application. This core material is then surrounded by a coil of wire, which generates a magnetic field when energized with electric current.The SRP4020-R47M exhibits excellent quality and performance, due to its special design and construction. The core material absorbs the generated magnetic field and the coil of wire forms a uniform magnetic field over the core. This helps to ensure efficiency and reliability, as well as reducing excessive heating of the core material. Additionally, the inductor is designed with a winding resistance of ~0.01 Ω, so as to maximize efficiency while preventing damage to the core.The SRP4020-R47M has a rated current of up to 4A, and is ideal for use in a range of power supply and radio transmitter applications. Its low profile 0.6” body further ensures easy assembly and minimal space requirements.In conclusion, the SRP4020-R47M is an excellent choice for fixed inductor applications, thanks to its special design and construction. Its ideal for use in a range of power supply and radio transmitter applications, while its low profile body ensures easy assembly and minimal space requirements. This induction coil is designed to generate a uniform and efficient magnetic field, which is essential for optimal performance.
