Fixed inductors, also known as chokes, are electronic components that store energy in an electric or magnetic field. They are used in power supplies, filters, and other circuits that require constant current or resistance. PA4303.822NLT is one such fixed inductors, which can be used in a variety of applications. In this article, we will discuss the application field and working principle of PA4303.822NLT.

PA4303.822NLT is a continuous-mode fixed inductor designed for applications using wide frequency bands. It has a high saturation current, low resistance, and excellent heat dissipation characteristics, making it ideal for applications requiring current stabilization. The inductance (L) of this component is 8.2 µH and the current range is from 0.001A to 0.4A.

PA4303.822NLT is typically used in the signal path of conduction-mode power circuits. It can also be used as a choke or filter in radio frequency (RF) control or intensively driven circuits. The inductor is ideal for use in low- and medium-frequency circuits, such as the output of high-current amplifiers or for rectifying power supplies.

The working principle of a fixed inductor such as PA4303.822NLT is simple. It consists of a wire or coil of material, usually copper or aluminum, wound around a magnetic core. When a current flows through the wire, it creates a magnetic field around the coil, which then induces an opposing voltage in the wire. This opposing voltage limits the flow of current as it passes through the wire. The higher the current, the greater the opposing voltage.

The current flow also creates a magnetic field. This magnetic field is measured in Ampere-turns (Ams). Ams is a measure of the force that the current is able to generate and is determined by the total length of the wire in the coil, and the current flowing through it. Depending on the application, the coil may be designed to store a specific amount of energy, or to allow a specific amount of current to pass through it.

As the current increases, there is an increase in the opposing voltage, and the magnetic field grows stronger. When the current reaches a certain point, the inductor reaches saturation, and the current cannot increase any further. This saturation point is known as the rated current, and is usually fixed at the highest current of the component in the design.

The maximum current flow of the PA4303.822NLT is 0.4A. If the current exceeds this limit, the inductor may be damaged. The component can handle frequencies up to 100kHz. The inductance is typically not affected by temperature changes, but it can be affected by mechanical vibration or shock.

In summary, PA4303.822NLT is a fixed inductor with a wide range of applications. It has a high saturation current, low resistance, and excellent heat dissipation characteristics, making it ideal for use in low- and medium-frequency circuits. Its working principle is based on the law of induction, and the maximum current flow is 0.4A. It is suitable for use in the signal path of conduction-mode power circuits, as well as in RF control or intensively driven circuits.
