Fixed inductors are electronic components designed with wired-loop conductors and fixed magnetic cores. Commonly referred to as “chokes”, they are used to regulate the flow of current within a circuit. They can act as a filter, allowing desirable frequencies to pass and rejecting undesirable frequencies. The ATFC-0201HQ-2N9B-T fixed inductor is a shielded power inductor designed for high-current applications in electronic devices, such as hard disk drives, power supplies, switching power supplies, and various other applications.

Application Field

The ATFC-0201HQ-2N9B-T fixed inductor is designed for use in electronic devices, such as hard disk drives, power supplies, and switching power supplies. It is a common component used for filtering, decoupling, and voltage regulation. This inductor is designed with an operating temperature range from -40°C to +125°C and a storage temperature range of -40°C to +125°C. It is well-suited for use in devices such as consumer electronics, car audio systems, and medical devices.

Working Principle

The operating principle of a fixed inductor is based on the inductive reactance, which is a measure of the opposition that the inductor provides to the alternation of current with changing frequency. This inductance can be expressed as an equation: XL = 2πfL, where f is the frequency and L is the inductance. The ATFC-0201HQ-2N9B-T fixed inductor has an inductance of 1.2mH. As the frequency increases, the inductive reactance increases as well. The inductor can work in either alternating current (AC) or direct current (DC) applications. In AC applications, the frequency of the current must be taken into consideration, as this will affect the value of the inductance.

In addition, the fixed inductor can also be used for choke applications, meaning that it can restrict or impede the flow of current within a circuit. This can be useful for suppressing electrical interference and providing electromagnetic compatibility, as the inductor can reduce incoming and outgoing electrical noise within the circuit. The resistance offered by the inductor is not affected by the frequency of the current, making it a reliable and consistent source of filtering and decoupling.

The ATFC-0201HQ-2N9B-T fixed inductor is a reliable component for high-current applications. It is designed to withstand high temperatures, and its current-handling capabilities make it suitable for use in a wide variety of electronic devices. Its fixed inductance and choke capabilities allow it to act as an effective filter and decoupling component, and its inductance and frequency-independent resistance make it a reliable and consistent component.
