Fixed Inductors

A fixed inductor is a type of inductor, which is designed to maintain a constant inductance despite any changes of external factors such as temperature, voltage, applied pressure or resistance. Fixed inductors are widely used in electronic circuits and devices. The M0820-86K is a particular type of fixed inductor which has a range of applications.

M0820-86K Application Field

The M0820-86K fixed inductor is mainly used as a common mode choke in high-frequency electronic systems, such as in switch-mode power supplies, telecommunications equipment, and consumer electronics. As it has a wide range of operating temperatures and frequencies, the M0820-86K is suitable for use in a variety of applications. It can be used to filters and suppress noise in all types of electronic circuits, particularly those with high-speed switching. It is commonly used to reduce the effects of EMI/RFI interference.

M0820-86K Working Principle

The M0820-86K works by storing energy in its inductor when exposed to a current. When the current changes, the inductor force tries to maintain a constant current and opposes the change. This phenomenon is known as inductance. The M0820-86K has a core material made of ferrite which has high saturation flux density and helps to increase the inductance values.The resistance of an inductor is called its AC resistance and is determined by the frequency of the AC signal. The M0820-86K has a high AC resistance and is thus suitable for use in high-frequency electronic circuits.The inductance value of the M0820-86K is also fixed, meaning that the inductor will maintain a constant inductance value despite any changes in the external environment. This makes it an ideal choice for noise suppression in high-frequency electronic circuits.

Conclusion

The M0820-86K from TDK is a type of fixed inductor that is ideal for use in a range of high-frequency electronic circuits. It has a wide range of operating temperatures and frequencies and a fixed inductance value meaning it can maintain a constant inductance in all environments. The M0820-86K also has a high AC resistance, making it suitable for use in noise suppression and EMI/RFI interference reduction applications.
