Fixed inductors, also known as coils or chokes, are an important electrical component that are present in a variety of different applications. SRP3012TA-R22M is a type of fixed inductor used for frequency-dependent needs. It has many useful features, and understanding the application fields and working principle of SRP3012TA-R22M can help engineers improve circuit efficiency and system reliability.

Structure

The SRP3012TA-R22M fixed inductor consists of a substrate made of insulating material such as iron, ferrite, polymer composite, ceramic, etc. The inductor itself sits on top of the substrate, with lead wires connected from the two ends of the inductor. The substrate provides mechanical support for the inductor, keeps it in place and protects it from environmental elements. It may also play a role in controlling the electrical properties of the inductor, making it easier to design a circuit.

Application Field

SRP3012TA-R22M is a frequency-dependent device, meaning that it defines a certain frequency range in which it will operate most efficiently. It is suitable for use in high-frequency analog and digital circuits that require a high current capacity, such as those used in mobile phones and other wireless devices. The SRP3012TA-R22M is also suitable for high speed applications that require precise signal conditioning, such as switching power supplies. It can provide low impedance at the frequency of operation and attenuate undesired signals outside the frequency range for improved signal integrity.

Working Principle

In a fixed inductor, an electric current is made to flow through a coil constructed with a conductor such as a wire. The coil accumulates and stores a magnetic field, which then induces an opposing current in the coil. This opposing current is called the “back EMF”, and it opposes the input current and reduces its amplitude. The current-limiting effect is useful in certain circuit applications that require a known current limit, such as power supplies and over-current protection circuits.

The SRP3012TA-R22M is a high-performance fixed inductor featuring high saturation current density and low parasitic resistance. With its high self-resonance frequency and low reactance, the SRP3012TA-R22M is ideal for high-frequency applications such as buck converters, switch mode power supplies and RF communication systems. Thanks to its optimized structure and material composition, the SRP3012TA-R22M can guarantee the highest level of reliability in its class.

Conclusion

The SRP3012TA-R22M is a fixed inductor that is suitable for high-frequency applications such as buck converters, switch mode power supplies and RF communication systems. It features high saturation current density and low parasitic resistance, allowing for improved signal integrity. Understanding the application fields and working principle of SRP3012TA-R22M can help engineers improve circuit efficiency and system reliability.
