Fixed Inductors

Inductors are electronic components used for storing energy in the form of a magnetic field. They are usually categorized by their construction, applications, and electrical properties. Fixed inductors are a type of inductor that are designed to generate a constant level of inductance with an adjustable output.

744771218 Application Field and Working Principle

The 744771218 fixed inductor is built with a planar construction, making it suitable for surface mount applications such as printed circuit boards or small PCBs. Due to its small size, the 744771218 is particularly well-suited for a range of automation and consumer products. The 744771218 fixed inductor works by using a combination of two inductances: an inductance created by the shape of the metal coil, and an external bias current induced in the coil from the current source. The net total of both inductances creates a solid-state, adjustable inductor unit. The operation of the 744771218 fixed inductor is relatively simple. The inductor is composed of two conducting coils, or “taps”, connected in series. When the primary fixed inductor is powered, an alternating magnetic field is created, which is then sensed and adjusted by the external bias current. This bias current is in turn adjusted by the gain adjuster which is connected to the primary fixed inductor. The alterations of the bias current allow for fine control of the total inductance, and thus enables the variation of its output. The 744771218 fixed inductor is able to provide a consistent performance even in harsh environmental conditions. It has a maximum operating temperature of 125°C, and also has the capability of withstanding high amounts of humidity, shock, and vibration. The 744771218 fixed inductor has many applications in the consumer electronics, automotive, and industrial sectors. It is extensively used in devices such as electric motors, AC power supplies, electric vehicles, and other high current equipment. It is also used for protection against surge currents, and is often found in combination with other electrical components such as capacitors and resistors.In conclusion, the 744771218 is a small yet reliable electronic component which provides excellent performance in a range of applications. Its reliable operation and modest price makes it a great choice for any electronic project.
