Introduction
Fixed inductors, also called non-variable inductors, are widely used in many market applications such as dc-dc converters, switching power supplies and EMI/EMC filters. There are numerous types of fixed inductors such as surface mount chip inductors, planar power inductors, power and common mode choke coils, shielded inductors and RF coil inductors.The M0820-26K fixed inductor is one type of surface mount chip inductors that is commonly used in a variety of applications.

Description
The M0820-26K is a type of surface mount chip inductor with a size of 8mm×20mm. It is a multipurpose, radial leaded inductor. It contains an integrated ferrite core, which gives the inductor high inductance and high power rated characteristics. It has a maximum DC resistance of 0.08Ω, with an inductance range of 8.20µH to 26µH. The rated current for the M0820-26K is 2.2A and an overall inductance tolerance of up to ±20%. It has a rated operating temperature range of -55°C to +125°C.

Application
The M0820-26K inductor is mainly used in dc-dc converters, switching power supplies and EMI/EMC filter applications. Due to its small size and low DC resistance, it is ideal for use in portable battery powered electronics, as well as in industrial and automotive applications. The M0820-26K inductor also has great suitability for mobile phone, Wearable electronics, tablet computer, data storage, home appliance, TV set, and communication devices etc.

Working Principle
The working principle of the M0820-26K fixed inductor is based on Faradays Law of Induction. This law states that when a changing current passes through a conductor, a magnetic field is produced around the conductor which is proportional to the rate of change of the current. The conductor will then be surrounded by a circular magnetic flux which in turn will induce a voltage in the conductor. This induced voltage is inversely proportion to the rate of change of the current. In the case of the M0820-26K fixed inductor, the induced voltage will act to oppose any changes in current, thus creating a resistive force to counter the changing current. This resistance to changing currents is what gives the inductor its high inductance and ability to store energy.

Conclusion
The M0820-26K fixed inductor is a versatile and widely used component with a variety of applications. It is a small size surface mount chip inductor which has high inductance, a low DC resistance and a high power rating. It is suitable for use in portable battery powered electronics, industrial and automotive applications. Its working principle is based on Faradays Law of Induction and this principle is utilised to create a resistive force against any changes in current, giving the inductor its high inductance and ability to store energy.
