Fixed Inductors: PA3784.181HLT Applications and Working Principle

Fixed inductors are widely used for their valuable qualities in many different types of applications. The Murata PA3784.181HLT fixed inductors are especially useful as they feature very low core losses and high self-resonance frequencies, making them great for noise filtering among many other uses. This article will explore the applications and the working principle of the Murata PA3784.181HLT fixed inductors.

Applications

The Murata PA3784.181HLT fixed inductors offer high quality performance in a wide range of applications. They are commonly used in noise filtering, providing superior noise suppression at high frequencies. They are also used in DC-DC power converters, providing inductive energy storage in situations which require fast current ramping at low frequencies. Additionally, they can be used in motor drives to provide smooth current supply to motors with varying loads, due to their superior frequency response. The Murata PA3784.181HLT fixed inductors are also widely used for power line buffering and for filtering applications in audio-visual devices. They offer excellent attenuation characteristics in the 20kHz-2MHz range, which makes them ideal for buffering power lines and isolating audio-visual circuits from any noise interference. Moreover, they can be used in frequency dividers and tuned amplifiers to design circuits with precise frequency control.

Working Principle

Fixed inductors work by converting current and voltage input to stored magnetic energy in an inductor core, which then creates a magnetic field around the inductor core. This magnetic field is induced in an AC circuit with a varying current, and its strength is determined by the amount of current flowing through the circuit. When the AC current in the circuit reverses direction, the magnetic field that was created also reverses, creating an electric field in the opposite direction. This creates an opposing voltage in the circuit, which then opposes the current flow, causing the current in the circuit to flow in the opposite direction. This opposing voltage is called an inductive reactance, which is the core principle of how fixed inductors work. The Murata PA3784.181HLT fixed inductors can handle up to 2.2A of current, providing secure filtration and noise suppression in all kinds of applications. Furthermore, these fixed inductors feature low resistance and very high self-resonance frequencies, making them ideal for many different applications.

Conclusion

The Murata PA3784.181HLT fixed inductors are ideal for noise filtering, DC-DC power converters, polarity switching, motor drives, power line buffering, and filtering applications in audio-visual devices. They convert current and voltage input into a stored magnetic energy in an inductor core, creating a magnetic field which opposes the current flow. This opposing voltage is called an inductive reactance, and is the core principle of how these fixed inductors work. They offer low resistance and very high self-resonance frequencies, making them a great choice for many different applications.
