Fixed Inductors
Fixed inductors are electronic components designed to introduce a specific amount of inductance into a circuit. Electromagnetic induction is the transfer of electric energy from one source to another. When an alternating current is generated in a coil of wire, a magnetic field is created that is exerted on another coil of wire in the same vicinity. This induction produces a voltage in the second coil and a current in the circuit.A fixed inductor, also known as a coil, is a component that is designed to introduce a specific amount of inductance into a circuit. They are available in a variety of sizes and shapes and consist of a coil of wire wound around a ferrite core. The core provides a magnetic field that increases inductance and reduces the resistance of the circuit.4470-28J is a type of fixed inductor used in low-frequency circuits. It is designed for use in applications that require high currents and long-term operation. It has a copper clad ferrite core and a copper wire coil. This type of inductor offers high inductance values and low choke losses.The 4470-28J has a 20mm diameter body and a 28mm length. It has a 2.7Ohm DC resistance and a 30mH inductance. It has a saturation current rating of 40A and can handle a maximum temperature of 250°C. It has a maximum DC bias current of 4.5A.The 4470-28J is typically used for noise filtering, power supply filtering, and other electronic circuits where high current and low voltage is required. It is used in low-frequency applications such as motor drives, LED drivers, AC rectifiers, and in telecom surge protection circuits. The inductor is ideal for use in high-efficiency, low-power designs due to its extended temperature range and temperature coefficient.The 4470-28J works on the principle of electromagnetic induction. When an electric current is applied to the inductor, a magnetic field is created that is exerted on another coil of wire in the same vicinity, inducing a voltage in the second coil and a current in the circuit. This is known as the inductance effect.The 4470-28J has several advantages over other types of inductors. It has a low saturation current, a high temperature rating, and can withstand high current levels without overheating. It is also designed to minimize power losses and has a high inductance value which makes it ideal for high-efficiency circuits.The 4470-28J is an ideal choice for a variety of electronic applications. Its compact size, high efficiency, and long-term reliability make it well suited for a range of low-frequency applications, including motor drives, LED drivers, AC rectifiers, and telecom surge protection circuits.
