Fixed Inductors

Fixed inductors are passive components that consist of a conductor wound into a coil, which is used in a variety of applications. A fixed inductor, also known as a "choke", is an electrical component designed to store energy in the form of an electromagnetic field, and is used to create a desired amount of inductance in a circuit.The ELJ-RF3N3DFB is an example of a fixed inductor, and it is an application-specific component. It is designed to provide high inductance in a small package, while also offering great efficiency and low cost. The ELJ-RF3N3DFB has a self-resonant frequency of 3.3MHz, a max current of 2.5A, and is magnetically shielded to minimize any interference.The application field of the ELJ-RF3N3DFB is for various communication technologies, such as Frequency Division Multiplex (FDM), Time Division Multiplex (TDM), and Quadrature Amplitude Modulation (QAM). It is also widely used in power supply circuits, for voltage regulation, filtering, and regulation.The working principle of a fixed inductor is that when an alternating current passes through the coil, an electromagnetic field is created. The alternating current flows in both directions in the coil, and the associated electromagnetic field induces a voltage in the coil, which opposes the current flow. This is known as the EMF (electromotive force) and is responsible for the inductance. The induced voltage is proportional to the rate of change of the current, and is a measure of the inductance of the coil.The inductance of a fixed inductor is determined by the number of turns in the coil, the area of the coil, and the permeability of the core. A large number of turns in the coil will increase the inductance, whereas a small number of turns in the coil will decrease the inductance. Similarly, the area of the coil will increase the inductance, whereas a smaller area of the coil will decrease the inductance. Last but not least, the permeability of the core affects the inductance, with a high permeability core increasing the inductance of the coil, while a low permeability core will decrease the inductance.The ELJ-RF3N3DFB is designed to offer the highest performance at the most economical costs. It is an ideal choice for circuits which require high inductance, with its high self-resonant frequency, high max current, and shielded magnetic core. This makes it suitable for a variety of applications, from communication technologies to power supply circuits.
