Fixed Inductors

A fixed inductor is a type of electronic component that is used for storing energy in the form of an electromagnetic field. Fixed inductors are used in a variety applications such as power management, audio/video circuitry, signal processing, radio frequency (RF) systems, and high-speed computing, making them some of the most important components in today’s electronics. One of the more commonly used types of fixed inductor is the PA4548.222NLT.

PA4548.222NLT application field and working principle

The PA4548.222NLT is a high-quality, precision fixed inductor with a 0.2mm2-10ppm/C temperature coefficient. This type of fixed inductor is designed for use in switching power supplies, DC-DC converters, and pulse power circuits due to its low ESR and low temperature coefficient. The maximum rated working voltage of PA4548.222NLT is 15VDC and the maximum rated current is 1A. The device also features high thermal resistance and low magnetic field emitted radiation.

The working principle of PA4548.222NLT is based on a concept called self-inductance. Self-inductance occurs when a changing electric field causes a voltage variation in a single electromagnet. The electromagnet consists of a coil wound around a core material. When the electric current runs through the coil, a unique magnetic field is created due to the coil\'s self-inductance. The magnetic field will cause an opposing voltage or reactance, which is also known as inductive reactance. The combined effect of inductive reactance plus the resistance of the wire creates an effective resistance, which is known as impedance. The greater the inductance, the higher the impedance.

As the electric current in the wire changes, the magnetic field and reactance change accordingly. This phenomenon is utilized in a variety of practical applications, such as the transfer of power from one circuit to another, control of power flow through transformers, and energy storage applications. The PA4548.222NLT fixed inductor is able to store significant amounts of energy when it is exposed to varying currents, making it one of the most important components in modern electronics.
