Introduction of Fixed Inductors

A fixed inductor is an electronic component consisting of a wire coil with a magnetic core. The inductor stores energy in its magnetic field and can be used in a wide variety of applications including signal filtering, voltage regulation, and radio frequency (RF) and power supply impedance matching. Fixed inductors are also widely used in logic circuits, communications and sound systems, and oscillators. ATFC-0402-1N8B-T is one of the specific type of fixed inductors.

ATFC-0402-1N8B-T Field of Application and Working Principle

ATFC-0402-1N8B-T fixed inductors are widely used in various electronics fields. Their most common application is in sensing coils, where they are used to detect the presence of ferromagnetic objects. Even though they are small components, they contain a large amount of energy; hence they are also found in high-power applications such as electric power systems and arc furnaces. Furthermore, they are frequently used as chokes in switching power supplies, AC-DC converter circuits, and automotive systems.

The ATFC-0402-1N8B-T feature high current ratings of up to 8.5A, low DCR (direct current resistance) of 0.06 Ohms, and low inductance values of 0.33 micro Henries. The inductance is frequency-dependent due to the self-resonance of the device. The inductor also has a high self-resonant frequency of up to 4 GHz which is suitable for high-frequency applications.

The working principle of a fixed inductor is based on Faraday’s Law of Induction. When a conductor is placed in a varying magnetic field or current, it induces a voltage in the conductor. This induced voltage is proportional to the rate of change of the current or magnetic field. When the current or magnetic field varies sinusoidally, the induced voltage will also contain a sinusoidal component, and such sinusoidal components are called alternating currents (AC).

The ATFC-0402-1N8B-T fixed inductor works in the same way, with an alternating current flowing through its wire coil. When a current is applied, it induces a magnetic field in the wire coil, which, in turn, induces an alternating current in the device. This alternating current can then be used for various applications, such as sensing, impedance matching, RF filtering, and voltage regulation.

Conclusion

ATFC-0402-1N8B-T fixed inductors are widely used in various electronics fields due to their high current ratings, low DCR (direct current resistance) of 0.06 Ohms, and low inductance values of 0.33 micro Henries. They can also be tuned to a wide range of frequency applications. The working principle of the device is based on Faraday’s Law of Induction, where a varying magnetic field or current induces a voltage in the conductor, which can be used for sensing, impedance matching, RF filtering, or voltage regulation.
