Fixed Inductors are an essential component in almost every commercial electronic device. The SO402-33NF2B inductor is one of the most common devices on the market. This article will discuss the application field and working principle of the SO402-33NF2B.

The SO402-33NF2B is a surface mount device (SMD) which is able to reduce both space and weight when compared to a traditional leaded package design. It is a low cost high density component with excellent electrical characteristics. Popular applications for this device include DC/DC converters, power supplies and switch mode power supplies (SMPS).

The SO402-33NF2B is classified as a low profile surface mount inductor. It is capable of handling frequencies up to 100MHz and provides excellent heat dissipation and current handling due to its low profile design. The inductor is made up of two parts; the core and the winding. The core is composed of a powdered iron and/or ferrite body which is then coated with a plastic or epoxy resin. The winding is made up of copper wire that is wound around the core. The type of wire used depends on the inductance value required, the current handling capability desired and the temperature range of the device.

The basic operating principle of all inductors is based on the electromagnetism theory. When an alternating electric current passes through a coil of wire, a magnetic field is created perpendicular to the wire. This field will then link to itself where the ends of the wire coil meet, forming an inductor. The voltage across the inductor will then create a magnetic field which interacts with the current. The current will be transformed to counter EMF when it attempts to rises and induce EMF to the falling current. The total current is controlled by the magnitude of EMF created by the inductor and the load resistance. Thus, those devices are used to help improve power efficiency in a range of applications.

The SO402-33NF2B inductor is a very versatile part as it can be used in a variety of applications, from DC/DC converters to switch mode power supplies. Its small size and high power rating make it ideal for system designs that require a compact yet efficient power solution. In addition, its low profile nature allows it to be placed on the surface of a PCB, eliminating the need for an external housing. Overall, the SO402-33NF2B is a great choice for those who are looking for a reliable, efficient, and cost effective solution.
