Fixed Inductors

Fixed inductors are electrical components that maintain a constant inductance for a large range of current. The LQP02TQ1N3B02D is one such component. This article will discuss its application fields and working principles.

Application Field

The LQP02TQ1N3B02D fixed inductor is primarily used in battery chargers, adapting purposes and filtering.For battery chargers, the inductor works to maintain a tight control on voltage in order to charge batteries at the fastest possible rate. In adapting applications, the inductor serves to modify a signal’s voltage and current to correspond to the desired output. It can also filter out noise and undesired frequencies in a signal. The LQP02TQ1N3B02D is suitable for use in a wide variety of electronics, such as consumer electronics, computer accessories, communications/networking, and automotive electronics.

Working Principle

The working principle behind the LQP02TQ1N3B02D is that it has a magnetic core, composed of ferrite or powdered iron, which stores energy in the form of magnetic flux when a current passes through it, creating a magnetic field. When the current is removed, the magnetic flux is also removed, releasing the energy in the form of heat.The inductor’s inductance is determined by the core material, size and shape of the inductor, as well as the current flowing through it. This is why it is important for inductors to be used within their specified ratings for inductance, current, voltage and power in order to ensure optimal performance. The LQP02TQ1N3B02D’s fixed inductance also helps to stabilize the current flowing through the circuit, minimizing sudden changes in voltage, which can cause electrical noise and power supply instability.

Conclusion

In conclusion, the LQP02TQ1N3B02D fixed inductor is a useful electrical component with a range of applications, including battery chargers, adaptation and filtering. Its working principle is based on a magnetic core that stores energy, with the inductance determined by the core material, size and shape as well as the flowing current. It is also capable of stabilizing current, helping to minimize power supply instability.
