In these circuits, the LQW04AN20NJ00D is used to filter out noise and allow the power supply to deliver a stable voltage supply to the circuit. It can also be used in audio systems, computers, TVs, automotive applications and motor controllers.

In addition to the previously mentioned applications, the LQW04AN20NJ00D inductor can also be used in RF circuits. It can be used to block undesired high frequency signals while allowing low frequency signals to pass through. It is also an effective component for noise suppression in high frequency circuits, such as cellular phones or Pagers.

Working Principle

The LQW04AN20NJ00D fixed inductor operates on the principle of inductance. When current flows through the inductor, a magnetic field is generated by the ferrite bead core. This magnetic field induces a voltage in the inductor, which opposes the change in current. This creates a counterforce to the current, which results in the reaction commonly known as inductance.

As the current increases, more energy is stored in the magnetic field, which causes the inductance to increase. This increase in inductance creates a greater counterforce to the current, which causes the current to slow down. When the current eventually stops flowing, the magnetic field collapses, the voltage drops to zero, and the energy is dissipated in the form of heat. This process is repeated every time the current flows through the inductor, allowing for the filtering of undesired frequencies.

Conclusion

In conclusion, the LQW04AN20NJ00D fixed inductor has a wide range of applications and uses a basic working principle to filter out undesirable frequencies. Its low ESL and ESR make it ideal for power supply and other noise-sensitive electronic applications. Its low DCR and temperature range make it an excellent choice for a variety of applications. By using the LQW04AN20NJ00D inductor, engineers can design reliable and durable electronic circuits for a variety of purposes.
