Fixed inductors refer to inductors with permanent magnetic fields. They are ubiquitous in circuits and can be used as components to serve several purposes. The SC2220-103, for example, is a high quality fixed inductor developed by Taiwan Semiconductor Corporation. The SC2220-103 is designed for high speed switching applications in machines. It is also capable of operating in a wide range of temperatures, from -40°C to + 125°C.

The SC2220-103 is designed with a very low DCR, so it has minimal temperature variation when switching. The inductance is also stable, nearly independent of the changing temperature and current. It also has a high self-resonance frequency, along with a 50% reduction of saturation current compared to other common inductors.

One of the main applications for the SC2220-103 is for filtering power supplies. It is effective in rejecting both common-mode and differential-mode EMI noise. With its reliability and small size, it can be used in many filtering applications. It can also be used in switching power supplies, supplying regulate DC voltages to various applications. In addition, it can be used as an inductive power component to boost the power efficiency in various motor and converter applications.

The SC2220-103 has a very simple working principle. It is composed of a permanent magnet core with copper wire windings located around it. The magnet core creates a magnetic field which creates a force pushing the electrons through the wire coil, generating a voltage. This voltage is equal to the number of Windings times the rate of change of the magnetic field in the core. The smaller the core, the higher the rate of change, and the higher the number of Windings, the higher the voltage generated.

Overall, the SC2220-103 is an excellent fixed inductor for a variety of applications. It is reliable and has an excellent temperature range, allowing for use in a wide range of temperature conditions. It has a low DCR and high self-resonance frequency, making it suitable for both filtering and power efficiency applications. Last but not least, its simple yet effective working principle makes it an ideal choice for high speed switching applications.
