Fixed inductors are passive components mainly used for storing energy in electric form. The CAL45TB220K is one representative of fixed inductors.

Application Field of CAL45TB220K

The CAL45TB220K is mainly used in various types of consumer electronics, such as laptops, mobile phones, tablets. Other applications range from automotive electronics, test and measurement, computer and peripherals. This kind of inductor has a very low profile, therefore it can be easily integrated into the limited space of the PCB.

Working Principle of CAL45TB220K

The working principle of the CAL45TB220K is based on electromagnetic field and the laws of induction. An electrical current can combine with the iron core in the middle of the inductor to generate an electromagnetic field. This magnetic field acts as a barrier blocking the passage of alternating current. The flux created this way forms a loop enclosing the conductor, which accumulates a certain amount of energy. This stored energy is released to the outside environments when either the load current or the supply current decreases, creating an induced current.

The role of the CAL45TB220K is mainly to filter the high-frequency components in the circuit, stabilize the output voltage, and reduce the interference caused by the alternation of current. Moreover, it can be used as transformers to reduce the size, weight, and cost of the circuit, or as inteference suppression inductors for elecrtrical interference, or simply for filtering.
