Fixed inductors are electromagnetic components, such as coils and chokes, designed to store electrical energy in the form of a magnetic field, usually for filtering or decoupling circuits. The SRR4828A-820M fixed inductor is an ideal choice for frequency-sensitive applications that require high performance and reliability at a low cost. This article will discuss the application field and working principle of the SRR4828A-820M fixed inductor.

SRR4828A-820M fixed inductors are suitable for use in many different high-frequency applications, including switching power supplies, power converters, telecom systems, consumer electronics, antenna matching, and other RF applications. They offer a low dcR with stable inductance and it is available in a wide range of values from 8μH to 1.8mH. The SRR4828A-820M inductor also offers tight inductance tolerance down to ± 20%, a high SRF and low DCR.

The design of the SRR4828A-820M fixed inductor is based on the principle of electromagnetic induction, which states that a change in the magnetic field around a conductor will induce an electric current in the conductor. In the case of an inductor, the SRR4828A-820M has a core of magnetic material such as ferrite, iron, or powdered iron which is wrapped with a wire winding. When an electrical current passes through the coil, a magnetic field is produced which causes the inductor to generate an opposing voltage. This voltage, known as the back EMF, opposes the applied voltage and limits the flow of current, thus limiting the power across the inductor.

The SRR4828A-820M also features a high saturation current and an excellent temperature stability. The saturation current is the maximum current that can be passed through the inductor without causing it to saturate, while the temperature stability allows it to maintain operation when exposed to extreme temperatures. In addition, this inductor features high Q-factor values, which ensures that the inductor can perform reliably with consistent inductance and low losses over the entire temperature range.

In conclusion, the SRR4828A-820M fixed inductor is a versatile and reliable component suitable for applications requiring high performance and reliability at a low cost. Its ability to resist saturation ensures stable performance, while the wide range of values makes it an excellent choice for many different frequency-sensitive applications. The design of the SRR4828A-820M fixed inductor is based on the principles of electromagnetic induction, which allows it to generate an opposing voltage and limit the current flow, resulting in power limits that protect the inductor from harm.
