LQW15AN3N3C8ZD

Fixed Inductors

LQW15AN3N3C8ZD is a fixed inductor constructed from a small cylinder of ferrite material with a wire coiled around it. The inductor is manufactured for operation at frequencies ranging from 500 kHz to 1 GHz, with an inductance value of 159 nH. When an AC signal is applied to it, the inductor acts to reduce the current flow and store a small electrical energy as a magnetic field. This field will cause a voltage to be induced in the inductance when the AC signal is removed.

Application Fields

The LQW15AN3N3C8ZD fixed inductor is predominantly used in communications and aerospace applications. It is often found in electronic systems such as TVs, satellite dishes, and radio remote control systems due to their superior performance in high frequency/RF (Radio Frequency) applications. Additionally, they are used in medical imaging equipment, where their high operating frequency allows for accurate imaging.

In addition to RF applications, fixed inductors are also used in power-supply designs. If a DC to AC conversion is needed, a fixed inductor can be used in a circuit to transform the voltage from DC to AC. The inductor is also often used in AC-to-DC conversions, particularly in power-supply designs. This is because the inductor can store energy in its magnetic field, allowing for the efficient transfer of energy between two circuits.

Working Principle

The fixed inductor relies on the principle of self-induction. When a current is applied to the inductor, a magnetic field is created. This field will cause a voltage to be induced in the inductor, known as Back EMF (BEMF) or counter EMF (CEMF).

This principle of self-induction is why inductors can be used in power-supply designs. The inductor will store energy from the AC signal, which will then be released when the AC signal is removed. This allows for more efficient transfer of energy between the two circuits.

The inductor also acts to reduce the current flow in the circuit it is connected to. This is because the inductor opposes any change in the current, which in turn reduces the amount of current flowing through the circuit. This can be useful in power-supplies, as it can limit the amount of current flowing through the device.

Conclusion

The LQW15AN3N3C8ZD fixed inductor is a versatile component with a wide range of uses. It is primarily used in RF and power-supply designs, due to its ability to store and transfer energy. The inductor works on the principle of self-induction, which causes a voltage to be induced in the inductor when an AC signal is applied to it. This voltage is then used to transfer energy more efficiently between two circuits.
