HK2125R22J-T Inductors, Coils, Chokes

Fixed inductors are resistive components used in electrical circuits. They are typically used to limit the current in a circuit, create timing or frequency-dependent signals, provide energy storage or help create a stable voltage. They are also commonly used to improve the performance of a circuit. The HK2125R22J-T is a type of fixed inductor that is often used in power supplies, voltage regulators and current-limiting circuits.

The HK2125R22J-T is an air gapped core, single-layer, wire-wound, fixed inductor. It has a maximum rated current of 220mA and rated inductance of 2.2uH. It is small, lightweight and has a high temperature rating of 155℃. It also has a low series resistance, resulting in minimal power losses and high efficiency in the circuits in which it is used.

The application field of the HK2125R22J-T is generally in power supplies, voltage regulators and current-limiting circuits. In power supplies, the inductor is commonly used for filtering and input/output filtration. It is also commonly used for suppressing high frequency noise, ripple, overshoot and undershoot in voltage regulators and current-limiting circuits. The inductor is also capable of providing additional current capability, allowing for higher efficiency.

The working principle of the HK2125R22J-T is based on Faraday’s law of induction. When a current passes through the inductor, a magnetic field is generated. This magnetic field, in turn, induces an electromotive force, or EMF, which opposes the change of current in the circuit. This creates a self-induced voltage (or inductance) in the opposite direction of the current flow. The inductance is proportional to the amount of current applied. As the current increases, the self-induced voltage also increases, and the total voltage drop across the unit is reduced.

The series resistance of the HK2125R22J-T is minimized and it can sustain a high current level, making it an ideal choice for applications requiring high current with high efficiency. This makes it an ideal choice for power supplies, voltage regulators and current-limiting circuits. In addition, the small size of the component makes it an ideal choice for circuit designs where space is at a premium.

In conclusion, the HK2125R22J-T is a type of fixed inductor with a low series resistance and high temperature rating of 155℃. It is often used in power supplies, voltage regulators and current-limiting circuits. Its working principle is based on Faraday’s law of induction, which states that a current passing through the inductor creates a self-induced voltage that opposes the change of current in the circuit. Its small size and high current capability make it an ideal choice for applications requiring high current and high efficiency.
