Fixed InductorsInductors are electrical components that are designed to store energy and resist change in current flow. The most common type of inductor is the fixed inductor. Fixed inductors, also known as air core inductors, are used in many electrical and electronic circuit applications. One of the most popular fixed inductors is the 1945R-28G. This article will discuss the application field and working principle of the 1945R-28G. The 1945R-28G is a type of surface-mounted inductor that is manufactured using an advanced thin-film process. It can provide low DC resistance and high quality factor. This type of inductor features a non-ferromagnetic core, a multi-layer shielding, a high-frequency operating system, and it can withstand peak voltages of up to 30V. Its temperature rating is up to 150°C.The 1945R-28G is mainly used in RF (Radio Frequency) and communications circuits. It is also used in power electronics applications such as switched-mode power supplies, DC/DC converters, and motor drives. Additionally, it can be used in antenna systems, logic circuits, and analog circuits such as amplifier stages and oscillators.The 1945R-28G can be used in a variety of circuits. It is designed to provide high stability and reliability. Its inductance value is very stable and has low DC resistance to ensure a low resistance signal path. This inductor also offers high current handling capabilities, enabling it to be used in high power applications.The 1945R-28G works on the principle of Faraday’s Law of Induction. This states that a current-carrying wire produces an associated magnetic field, which is proportional to the current in the wire. When this current changes, the associated magnetic field also changes. This change in magnetic field induces an electromotive force (EMF) in the coil, which opposes the change in current. Inductors can be used to limit the rate of current change, as well as to filter out AC signals from DC signals. They are also used in oscillator circuits, which use the changes in current and the associated magnetic field to produce oscillation.The 1945R-28G is an ideal inductor for many applications. Its thin-film construction and non-ferromagnetic core make it a reliable and stable component, while its high current handling capabilities and low DC resistance provide a versatile and efficient solution for a wide range of circuits.
