Fixed inductors are electrical components composed of a tightly coiled wire, often with a core of magnetically conductive material, which are used in a variety of electronic applications. They are used to either convert alternating current (AC) to direct current (DC) or sustain a given current while providing a self-induced voltage. The most common and widely used inductor is the PB2020.153NL.

The PB2020.153NL is a type of non-polarized vertical molded power inductor. It is designed to offer high energy storage, low losses, and low equivalent series resistance from 1mH to 10.2mH. Its characteristics make it suitable for flyback transformers, high efficiency lighting, high frequency resonant circuits, battery chargers, and other related applications. Its aerial case is rated up to 4A with exceptional performance at low temperatures, making it ideal for power supplies and switching voltage regulators.

When it comes to working principle, the PB2020.153NL works like any other type of inductor. When a varying current is applied to its terminals, the wire that makes up the inductor produces an opposing magnetic field. This field reacts with the applied current, inducing an opposing voltage in the wire, which is larger than the current itself. This "back-emf" or "self-induced voltage" tends to impede, or "resist," the current from entering the inductor. The magnitude of the inductance is proportional to the number of turns of wire and the nature of the core material.

The PB2020.153NL can be used in a variety of applications depending on the size of the inductor, though it is particularly popular in high power circuits, and as a power-packaging component. Commonly used in switching power supplies and DC-DC converters, it works best when placed between the power transistor and the primary winding of the inductor. It can also be used in place of a choke coil in choke-mode power supplies. Additionally, it can be used in portable devices, such as cell phones, to reduce the power consumed by a circuit.

The versatility of the PB2020.153NL makes it well suited for high efficiency converters, flyback transformers, LCD backlights, and transformer circuits. Its ability to create electromagnetic fields with a high degree of stability, and its excellent performance dynamically and over temperature makes it the ideal choice for these types of applications. Additionally, its characteristics make it ideal for use in audio circuits. As these components have a small footprint, they are also suitable for use in small PCBs.

The PB2020.153NL is part of the PB2020 series, and its characteristics make it a very versatile inductor. With its high current rating and low resistance properties, it is particularly well-suited for high power applications. Its small footprint and lower power consumption make it suitable for use in portable devices, allowing for more efficient electrical power systems. As such, it is an incredibly useful and important component in the world of today’s electronics.
