Introduction

Fixed inductors, otherwise known as chokes, and used throughout electronics industries and applications for a variety of purposes, including noise-reduction, filtering, and blocking of high frequency signals. The ATFC-0201HQ-3N0B-T is a high quality, high performance ceramic core, surface mount ferrite bead inductor; and belongs to the class of fixed inductors.

ATFC-0201HQ-3N0B-T Application Field

Common application fields for these type of fixed inductors include high power AC-DC power supplies, switching regulators, radio systems, frequency conversion, and communication circuits; and ATFC-0201HQ-3N0B-T has no exceptions. This particular fixed choke has been specifically designed for hot spot reduction in automobiles; and can continually operate at temperatures up to 125°C, making it ideal for a range of vehicular applications. In addition, this ceramic core ferrite bead inductor is also suited for many industrial and robotics applications.

ATFC-0201HQ-3N0B-T Working Principle

Fixed inductors are designed to resist changes in current, meaning a change in the current can result in an increase or decrease in voltage that is inverse of the current ratio. This property of inductors is called self-inductance; and when the choke is placed in a device such as a power inverter, it will act as an energy-storage device. Its initial energy is stored in the form of a magnetic field, which is gradually released if it is suddenly energized. This happens over an oscillating period, as the time between alternating current pulses become shorter and fluctuate longer.

The ATFC-0201HQ-3N0B-T is particularly useful for suppressing noise in high power AC-DC power supplies, as it can act as a resistor for radio-frequency interference. In addition, the ceramic core ensures an optimized resonance frequency with improved mechanical stability, meaning noise-free operation for the power supply. The inductor can also effectively reduce high frequency signals, preventing these signals from interfering with other electronic circuits.

Conclusion

The ATFC-0201HQ-3N0B-T belongs to the class of fixed inductors, known for their noise-reduction, filtering, and blocking cause to high frequency signal applications. This ceramic core ferrite bead inductor is primarily used in automobile applications, for managing hotspot reduction; as well as a range of industrial and robotics applications. The working principle of fixed inductors is based on the concept of self-inductance, where they act as an energy storage device for a fluctuating power supply. The ATFC-0201HQ-3N0B-T can reduce radio-frequency interference, as well the suppression of high frequency signal disturbances.
