Fixed inductors are components found in almost all electronics. SRR1280A-4R7Y is an example of a fixed inductor which is widely used in various applications. This article provides an overview of its applications and working principle.

SRR1280A-4R7Y is an inductor that has an inductance value of 4.7µH. It is a wideband, high performance, relatively low-cost inductor. It is widely used in switching power supplies, mobile phones, chargers, computers, and other electronic applications. It has a wide operating frequency range of 0.35-2 GHz.

The SRR1280A-4R7Y inductor is made up of three parts: the coil, core, and enclosure. The coil consists of two windings of copper wire that have been electrically insulated from each other. The core consists of a high permeability material that amplifies the magnetic field produced by the coil. The enclosure holds the parts of the inductor together and prevents any kind of electrical interference. The typical operating temperature range is -40 to +85°C.

The SRR1280A-4R7Y inductor is mainly used in power supplies, such as mobile chargers, computers, and other electronic applications. This type of inductor is especially suitable for power supply modules with high frequency switching. It is also suitable for high current, high frequency filter applications, as well as for broadband impedance matching circuits. It is a stable, high precision inductor that can reduce component size due to its high density and low profile.

The SRR1280A-4R7Y inductor works on the principle of electromagnetic induction. When current passes through the coil of the inductor, a magnetic field is created around it. When the current changes, this magnetic field collapses, inducing a voltage across the coil. This voltage opposes the current, producing a self-induced voltage which provides power supply stability .

The SRR1280A-4R7Y inductor is an essential component for many electronic applications. Its wide operating frequency range, compact size, and stable performance makes it a versatile inductor that can be used in various electronic circuits. It is a reliable inductor that can provide power supply stability and improve system efficiency.
