Fixed Inductors

Fixed inductors, also known as non-variable inductors, are electronic components that are used to control the flow of current in electrical circuits. They are the most essential components used in the development of electrical and electronic circuit systems, including radio frequency (RF) applications. The CBL2012T220M fixed inductor is an example of such a component.

CBL2012T220M Application Field and Working Principle

The CBL2012T220M is a hi-Q standard leaded SMT inductor in vertical on-board form. The overall size is small and is highly suitable for mobile communication circuitry. The component works as an alternative to ceramic and conductive polymer multilayer chip inductors. It is designed for operating frequencies up to 50 MHz. It also provides very low DC resistance and a Q factor of up to 30.

The application field for the CBL2012T220M includes cell phones, PDAs, digital cameras, personal entertainment devices, mobile storage devices and wireless applications. The component is also ideal for impedance-matching networks. It is designed to function as a driver, receiver, buffer amplifier or voltage regulator circuit.

In terms of the working principle, the CBL2012T220M fixed inductor consists of a coil of wire wound around a small core of ferromagnetic material. This core material is typically composed of iron or steel. When a voltage is applied to the two terminals of the inductor, a magnetic force is created and the core of the inductor becomes magnetized. This creates a magnetic field that induces a voltage in the inductor coil.

The inductance of the CBL2012T220M fixed inductor depends on the number of turns in the coil, the area of the core and the material. The voltage generated in the coil is proportional to the rate of change of the current flowing through the inductor. Higher frequencies cause the voltage to reach higher levels since the rate of change in the current also increases with frequency.

Conclusion

The CBL2012T220M fixed inductor is an indispensable electronic component for mobile communication applications. This component is designed to operate at frequencies up to 50 MHz and has a Q factor of up to 30. As it consists of a wound coil around a ferromagnetic core, it generates a voltage that is proportional to the rate of change of the current flowing through the inductor. This component is used for a wide range of applications in modern electronics, such as cell phones, PDAs, digital cameras, personal entertainment devices, mobile storage devices and wireless applications.
