Fixed Inductors

Fixed inductors are used in a variety of applications. Most commonly they are used in power supplies, telecommunication systems, consumer electronics, automobiles, and aerospace applications. Fixed inductors are static components that store energy in the form of an electrical magnetic field created by the coil of a conducting wire, such as copper. A fixed inductor has two basic components, an inductor winding and a core.

Fixed inductors are divided into two categories: open-frame type and closed-frame type. Open-frame type inductors are typically used in low-current, high-frequency applications where the core needs not be isolated from the inductor winding. Closed-frame type inductors are typically used in medium- to high-current applications where the core needs to be highly secured from the inductor winding.

The 7447779212 fixed inductor has an open-frame type construction and is a multi-layer, soft ferrite core with 20.7mm by 9mm height and a total 32 layers. This inductor has a rated current of up to 0.3A and an operating temperature range of -40°C to 85°C. This inductor has a working frequency of up to 2.2GHz, a self-resonant frequency of up to 10GHz, and a primary inductance of 12.5µH ±10%.

The working principle of the 7447779212 fixed inductor is based on the principle of induction. This principle states that a changing magnetic flux causes an electric current to flow in a nearby circuit. This inductor works by creating a magnetic field, generated by AC current, which induces an electric field in the vicinity of its coil. This electric field then in turn induces a counter-electromotive force that opposes any increase in current flowing through the inductor\'s coil. By doing this, the inductor is able to control the electrical current in the circuit.

In Summary, the 7447779212 fixed inductor is a multi-layer ferrite core inductor with an open-frame type construction. This inductor has a rated current of up to 0.3A and an operating temperature range of -40°C to 85°C. Its working frequency is up to 2.2GHz, a self-resonant frequency of up to 10GHz, and a primary inductance of 12.5µH ±10%. Its principle of induction has been stated above.
