Fixed Inductors

A fixed inductor (or fixed-value inductor) is an inductor that is not designed to be adjusted in its inductance value. Fixed inductors are used as components in electronic circuits to provide predetermined current-limiting effects, magnetic shielding, or for other purposes. Common types of fixed inductors include air core inductors, iron core inductors, toroidal inductors, ferrite bead inductors, and printed circuit board (PCB) inductors, among others.

7447779115 Application Field and Working Principle

The 7447779115 type fixed inductor is a radial leaded, iron-core power inductor that has been developed especially for automotive applications. It can be used as an inductive load component in fuel injector drivers, headlamp converters, and other automotive systems. The inductor is able to operate at extremely high temperatures, up to 150°C, and has a low resistance of only 0.14 ohms. It also has low DCR variation over a wide temperature range and high ripple current capability, up to 35A, making it suitable for applications where high reliability is required.

The 7447779115 fixed inductor has a radial leaded, iron core structure and operates by the principle of induction. The inductor has two terminals which are connected to a power source. When the inductor is connected to the power source, current begins to flow through the inductor, creating a magnetic field which induces a voltage across the inductor\'s leads in the opposite direction of the current. This counteracting voltage produces an opposing force on the current, reducing its rate of flow (this is known as inductance). This allows the inductor to store energy (in the form of a magnetic field), and is what gives inductors their characteristic impedance.

The working principle and application field of 7447779115 fixed inductor make it suitable for automotive applications where high power, high efficiency and reliability are required. It is ideal for applications where it is critical to limit the current, improve noise immunity, or provide magnetic shielding. The 7447779115 inductor is also suitable for use in power supplies and medical instruments, as well as in other applications that require precise current control or noise reduction.
