Fixed Inductors

Inductors are electrical components designed to store energy in the form of a magnetic field. A fixed inductor, also known as a choked coil, is an inductor that has a single, predetermined inductance value set at the time of its manufacture. The 7447715330 fixed inductor is a type of fixed inductor that is designed for the lower to middle power range applications.

Applications

The 7447715330 fixed inductor is specifically designed for use in telecom and power converters. It is typically used to filter voltage and current harmonics in order to maintain the integrity of a signal as it is transmitted or received. It can also be used to reduce noise and improve EMI compatibility by providing a low inductance path that will divert unwanted EMI. Additionally, it is commonly used in switching power supplies and general purpose DC to DC converters.

Working Principle

The 7447715330 fixed inductor works according to Faraday’s law of induction, which states that the induced electromotive force (emf) in any closed circuit is equal to the rate of change of the magnetic flux linkage of the circuit. An inductor coils is an excellent example of Faraday’s law, as it produces a magnetic field when an alternating current passes through it. The 7447715330 fixed inductor is made up of multiple turns of wire, usually wound around a core of ferrite material. When current runs through the coils, an electromagnetic field is created that stores energy. This stored energy is ultimately released back into the circuit when the current decreases, creating a magnetic field capable of generating a voltage.

Structure and Construction

The 7447715330 fixed inductor is designed to operate at frequencies up to 3MHz, with a rated current of 5A. It measures 25.8mm x 22mm x 15.4mm in size and weighs 17 grams. The inductor is made of high-grade ferrite core material and includes an electrostatic shield. Its winding is composed of a special formvar line, which is extremely flexible and durable. The windings are also designed to be self-extinguishing for improved safety.

Advantages

The 7447715330 fixed inductor has many advantages, including its high-frequency operation, low impedance, high insulation resistance, and low power loss. It is also designed for high-accuracy current regulation and is compliant with RoHS and lead-free directives. In addition, the ferrite core material ensures excellent temperature stability and low losses, and it also provides good low and high frequency characteristics and excellent radiation characteristics.

Conclusion

The 7447715330 fixed inductor is an efficient and reliable solution for high-frequency applications that require low impedance and low power loss. It is designed for telecom and power converters, and is also suitable for switching power supplies and general purpose DC to DC converters. Its ferrite core and formvar winding provide excellent temperature and radiation characteristics, whilst also providing good low and high frequency characteristics. Additionally, it is compliant with RoHS and lead-free directives, making it a safe and reliable solution for electrical applications.
