Fixed inductors are inductors with physical windings. They are likened to manually wound coils in that they have no adjustable capability. This article is about the application field and working principle of the fixed inductor, the ISC1812ER101K.

Application Field

The ISC1812ER101K is a fixed inductor specifically designed for use in power one solutions. It is ideal for applications in signal processing platforms, which require robust performance in the presence of strong electromagnetic interference or in extreme temperature ranges. It is also particularly suitable for dedicated industrial and automotive applications, such as power supply, power conditioning, switch-mode power supply design, and filtering.

Working Principle

The ISC1812ER101K is based on an isolated winding design and offers a 100µH inductance value. This inductance value is determined by the size of the coil windings and the number of turns of the windings. A higher number of turns means a larger inductance value. The inductance of any inductor can be adjusted by changing the number of turns or the size of the coil windings.

The ISC1812ER101K is wound on a ferrite core material that runs through the middle of the winding coils. This core material is made up of ferric oxide and iron, or iron and silicon, that acts as an electro-magnetic material by forming a strong magnetic field around the coil winding. The magnetic field produced by the core material helps concentrate flux lines around the coil windings, thus increasing the inductance of the winding.

It also has an ability to store energy, and it can be released via an electrical circuit when the current is being switched off. This stored energy is stored in an electro-magnetic field and then released when the magnetic field collapses. The stored energy is then used to maintain the current flow in the circuit, thereby providing a smooth transition from current to no current situations. Lastly, the ISC1812ER101K also features excellent heat dissipation and stability.

Conclusion

The ISC1812ER101K fixed inductor is a reliable and robust device designed for power one solutions. Its ferrite core material helps concentrate flux lines and thereby increase inductance. Furthermore, it has excellent heat dissipation properties and stability. Its applications include signal processing platforms, dedicated industrial and automotive solutions, power supply, power conditioning, switch-mode power supply design, and filtering.
