Fixed inductors, or sometimes known as chokes, are one type of electrical component, often found in electronic circuits, that stores electrical energy. The SRR3011-330YL inductor is a common, non-shielded, surface mount type inductor used in a variety of applications, such as high-frequency oscillators, audio filters, and voltage control circuits. This article will explain the application field and working principle of SRR3011-330YL.

Application Field

The SRR3011-330YL it is a high current, low inductance, surface mount power inductor, and is available in a 330µH nominal inductance rating. Its exceptionally low resistance and high current capabilities allow it to be used in a variety of power management and DC/DC conversion applications. This inductor is used in power supplies, DC/DC converters, and battery charge/discharge solutions for portable and consumer applications. Due to its high current/low inductance characteristics, it can be used in DC/DC buck-converters to reduce the number of output inductors required.

The SRR3011-330YL is ideal for supplying power to modern high speed microprocessors, FPGA’s, and other digital IC’s that require high-density power. Its surface mount design and various operation temperature ratings make the SRR3011-330YL well suited for applications requiring high power and current over a wide range of operating conditions. It is suitable for use in automated assembly and can create very compact power conversion circuits.

Working principle

An inductor is an electrical component that consists of a coil of wire. The SRR3011-330YL is a particular type of inductor known as a “fixed inductor” because its inductance value is stable over a wide range of frequencies and temperatures. This means that the SRR3011-330YL will not substantially change its inductance, or the amount of electrical energy it can store when exposed to changes in frequency or temperature.

As alternating current (AC) passes through the SRR3011-330YL coil, it acts like a small transformer and induces a magnetic field inside the coil. The amount of magnetic flux created by the electric current passing through the coil creates an electro-magnetic field, thus causing the inductor to oppose any changes to the current. This opposing force is known as ‘inductive reactance’, which is the measure of opposition to AC current, and is related to the inductance of the inductor.

The SRR3011-330YL is capable of storing more electrical energy than other inductors because of its low electrical resistance. This makes it ideal for applications where high current is required over a wide range of frequency and temperatures. This also makes the SRR3011-330YL more efficient than other types of fixed inductors.

Conclusion

The SRR3011-330YL is a surface mount, non-shielded inductor ideal for power and current management applications in modern portable and consumer electronics. Its low resistance and high current capabilities make it suitable for use in DC/DC buck converters and other power/current conversion circuits. The SRR3011-330YL is suitable for use in automated assembly and can create very compact power conversion circuits. By understanding the SRR3011-330YL’s application and working principles, designers can better understand and utilize this inductor for different applications.
