It can also be used in automotive systems for the purpose of filtering out power pulsations or engine noise. In addition, it can also be used in single and multiple-phase switched mode power supplies for the purpose of filtering out any unwanted signals.

Working Principle

The 78438335220 fixed inductor works by storing energy in its magnetic field. When a signal is fed into the inductor, the alternating current creates a changing magnetic field. This changing magnetic field induces an opposing current in the inductor. The inductor stores this energy, and when the current is removed from the inductor it will continue to supply this stored energy until it dissipates. This helps to reduce ripple and noise in the signal, providing a smoother response.

Conclusion

The 78438335220 fixed inductor is a cylindrical-shaped component designed for use in low-voltage, low-power applications. It has a high inductance and a low DC resistance that make it suitable for filtering, energy storage, and voltage attenuation performance. The component is ideal for use in power supplies, audio applications, and automotive systems where it can provide enhanced filtering. It works by storing energy in its magnetic field and providing an opposing current when a signal is applied.
