Fixed inductors are components used to store electrical energy in magnetic form in an electric circuit, providing secure energy transfer. The CAL45TB122K is a reliable and dependable inductor manufactured by Coilcraft specifically designed for a few key applications, and its working principle is relatively simple.

Applications and Uses of CAL45TB122K

The CAL45TB122K provides two key applications: filtering, noise reduction, and low and stable impedance levels, making it an ideal choice for electrical engineers. It also has a low price tag, allowing for efficient use of a limited budget. The frequency range is quite wide, which is why it is especially suitable for power applications, such as power supply units.

The inductor\'s low-profile design also makes it suitable for applications in confined spaces, which is perfect for automotive, industrial, and smart home applications. CAL45TB122K is widely used in switch-mode power supplies, and it is easy to control due to its fixed inductance value and excellent frequency response.

Working Principle of the CAL45TB122K

The working principle of this inductor is simple. It works by storing energy in electric and magnetic fields. It also acts as a conductor and allows electrical current to flow around a circuit via the magnetic field. Electrical energy is then converted into magnetic energy, which is then converted back into electrical energy, creating a cyclic effect in the circuit. This process is known as "induction" and is the basis of the inductor\'s functioning.

As current flows through the inductor, it creates a magnetic field, which in turn induces a voltage on the opposite side of the coil. This induced voltage is proportional to the rate of change of current flowing through the coil, and it produces an opposing voltage, which is the motor effect of the inductor, dissipating electrical energy as a magnetic field.

When the current changing rate is slower and the time constant is longer, a stronger magnetic field is induced. This stronger magnetic field is better for applications where noise reduction or filtering is desired. On the other hand, if the changing rate is much faster, the inductor\'s magnetic field will be weaker, offering power DC/DC applications.

Conclusion

CAL45TB122K is a fixed inductor manufactured by Coilcraft, which has a wide frequency range and low-profile design, making it suitable for automotive, industrial, smart home, and power supply applications. With its fixed inductance value and excellent frequency response, it is easy to control. As electrical current flows through the inductor, it creates a magnetic field, which in turn induces a voltage on the opposite side of the coil, creating a motor effect that dissipates electrical energy.
