Introduction to Fixed Inductors

A fixed inductor, also known as an inductor, is an electronic component that uses an electric current to create a magnetic field. Inductors are found in many different kinds of electrical and electronic circuits, and are used for a variety of purposes such as partnering with capacitors to form tuned circuits, helping store energy, and providing electrical impedance to a wire. Inductors are often used in radios, television sets, cellular phones, personal computers and other electronic equipment.

SRR0804-181K Fixed Inductor Application Field and Working Principle

The SRR0804-181K fixed inductor is a surface mount, lead free, chip inductor, suitable for high frequency applications where space is at a premium. This inductor is made with Ni-Zn magnetic core material, and has been designed to be compatible with standard surface-mount processes. The advantages of this inductor are that it has a small size, which makes it ideal for electronic applications in tight and confined spaces. The SRR0804-181K has an effective rated inductance of 0.18mH, an operating temperature range of -20°C to 80°C and can withstand up to 2A of peak temproary current. This inductor is rated for a saturation current of 1 A, and has a self-resonant frequency of 10MHz. When an alternating electric current passes through the SRR0804-181K fixed inductor, the reactance of the coil opposes the passage of current resulting in an inductive reactance. This reactance, which depends on the frequency of the current, can be represented by a characteristic impedance determined by the transformer ratio between the primary and secondary winding. This characteristic impedance allows the inductor to be used to couple two circuits, isolating the circuits from each other while still allowing an electrical current to pass.The SRR0804-181K fixed inductor can be connected to various other electronic components such as capacitors, resistors, and diodes. Connecting an inductor in series with a capacitor creates a tuned circuit, which is used in radios and audio amplifiers. Connecting two inductors in a transformer configuration creates an electromagnetic field, which is used for signal and data transmission.

Conclusion

The SRR0804-181K fixed inductor is an ideal choice for applications where space is at a premium and high frequency is needed, such as radios, television sets, cellular phones, personal computers, and other electronic equipment. This inductor is a surface-mount, lead free, chip inductor that can provides with a characteristic impedance to couple two circuits, as well as create tuned circuits and transformers. With its small size design, the SRR0804-181K is an ideal choice for many electronic projects.
