Fixed Inductors

Fixed inductors are passive components that store and release energy in the form of an electric or magnetic field. The effects of inductors are often used in electrical and electronic devices such as filters, power converters, oscillators, and receivers. Inductors can be classified by their physical geometry (e.g., cylindrical, planar, or transverse), material (e.g., iron, copper, aluminum, or ferrite), and configuration (e.g., tapped, ganged, or trimmable).

744777928 Application Field and Working Principle

The 744777928 fixed inductor is a cylindrical type component containing a ferrite core with two or more coil windings around it. The 744777928 has an inductance value of 0.17mH, making it suitable for many applications including filtering, switching power supplies, and driving loads such as motors and speakers. The 744777928 can also be used to generate or store a magnetic field for use in electrical transducers and resonators.

The working principle of the 744777928 fixed inductor relies on the principle of electromagnetic induction. When a current passes through the inductor’s coil, a magnetic field is created which in turn causes a voltage to be induced in the coil. This voltage is proportional to the rate of change of the current, resulting in an inductive reactance which opposes any changes in the current. The inductance value of the inductor controls the amount of opposition, allowing it to be adjusted to the desired levels.

The 744777928 has two distinct features which make it particularly useful for many applications. Firstly, the component is shielded against external electromagnetic interference, meaning that it can be used in radio frequency circuitry without introducing too much noise. Secondly, the 744777928 is also designed to be able to operate at high temperatures, which is a requirement for many electronic components.

The 744777928 fixed inductor is therefore an ideal component for many applications, and is particularly useful for those which require high frequencies, reliable performance, and protection against electro-magnetic interference. As its inductance value can be adjusted, the 744777928 is also suitable for pulse and clock circuits, meaning it can be used in a wide range of applications.
