A fixed inductor, such as a CAL45TB680K-1K, is an electronic component used to store and release energy in a circuit by creating a magnetic field when an alternating current passes through it. Fixed inductors are commonly used in electronic circuits to filter, condition, and regulate electrical signals. The guiding principles and application fields of the CAL45TB680K-1K fixed inductor will be discussed herein.

Principle of Operation

An inductor is an electronic component with two terminals, where a coil of wire is wound around a core material. When an alternating current of voltage is applied to the inductor, it creates a magnetic field which stores electrical energy. This energy is then released back into the circuit as the magnetic field dissipates.

In a fixed inductor, the core material is typically a ferrite material, while the number of turns of wire, the winding orientation, and other parameters determine the inductance value. Fixed inductors can be designed to have inductance values as low as a few nanohenries (nH) or as high as hundreds of millihenries (mH).

The CAL45TB680K-1K is a fixed inductor designed to have an inductance value of 680 millihenries (mH) and a rated current of 1,000 milliamps (mA). It has a low temperature coefficient and is designed to be self-shielding, meaning that the inductance value does not change significantly when exposed to electromagnetic interference.

Applications

Fixed inductors are used for a variety of applications in electronic circuits. Commonly, they are used for signal filtering, steady-state current limiting, suppressing transients and noise, ensuring correct circuit impedance characteristics, and providing a path for current to flow in specific directions.

The CAL45TB680K-1K fixed inductor is frequently used in power supply filtering circuits and power supply reduction applications. It is also used in circuits with high transient noise and large EMI susceptibility, such as automotive electronics. In addition, it is often used in automotive applications which require temperature and vibration resistance, such as headlights and electronic brake systems.

The CAL45TB680K-1K is a versatile fixed inductor that can be used in many different types of applications. Its low temperature coefficient and self-shielding qualities make it an ideal choice for applications that require reliability and precision.

Conclusion

The CAL45TB680K-1K fixed inductor is an electronic component designed to store and release energy in a circuit by creating a magnetic field. It has a rated current of 1,000 milliamps and an inductance value of 680 millihenries, making it ideal for power supply filtering, power supply reduction, transient noise and EMI suppression, and automotive applications.
