Introduction to SRR1208-221KL

Fixed inductors are components that are typically composed of an inductor core, a wire winding, and a conductive housing. This article will provide an introduction to the SRR1208-221KL, a type of fixed inductor, and discuss its application field and working principle.

Overview of SRR1208-221KL

The SRR1208-221KL is a fixed inductor designed for high-frequency circuits. It is a small component that can be easily integrated into most electronic applications due to its light weight and small dimensions. It is also known for its high coupling efficiency, low losses, and high impedance.The SRR1208-221KL has an air core with an inductance of 22.1uH, an operating temperature range of -40°C ~ 85°C, and a tolerant of ±20%. It also has a height of 5.0mm, a width of 9.8mm, and a length of 14.7mm.

SRR1208-221KL Application Field

The SRR1208-221KL is designed to meet the stringent demands of modern electronic applications. Its small form factor and high impedance make it particularly suitable for use in high-frequency circuits, such as filter circuits, power supply circuits, and signal processing circuits. It is also widely used in communications, broadcasting, and automotive industries.

SRR1208-221KL Working Principle

The SRR1208-221KL is composed of a core, a winding, and a housing. The core acts as the magnetic material, where the winding connects the current-carrying parts of the circuit. The housing helps to shield the inductor from external electromagnetic interference and prevent the components from coming into contact with each other. When current is passed through the winding, a magnetic field is generated within the core. This magnetic field can induce voltage in other parts of the circuit, which in turn can be used to generate a signal, filter noise, or provide power. The inductance of the inductor, which is a measurement of the opposition to the current, can be adjusted by adjusting the number of turns of the winding, as well as the size and shape of the core.

Conclusion

Fixed inductors, such as the SRR1208-221KL, are widely used in modern electronic products due to their versatility, high coupling efficiency, and small size. This article has provided an introduction to the SRR1208-221KL, discussed its application field and working principle, and shown how it meets the high demands of electronic applications.
