Fixed Inductors: 4922-36H Application Field and Working Principle

Fixed inductors, are an important group of electrical components that act like a coil, creating an electromagnetic field when an electrical current is passing through them. Fixed inductors are commonly used as part of a system\'s power lines and as secondary-side interference filters in power supplies. The 4922-36H inductor is a good example of the variety of fixed inductors currently on the market.

The 4922-36H is a 6-pin, fixed inductor, with a total lead length of 37.8 mm and a single-section lead length of 18.9 mm. The inductor is made from a ferrite material with a flat porosity of 0.2mm. It has a rated current of 2A, and an inductance of 36uH. The rated voltage of the inductor is 80V, DC, and it has a tolerance rating of +20/-20%. In addition, the 4922-36H also has an operating temperature range of –40°-105°C, and an insulation resistance of 1000Mohm/100V (min). Its isolation voltage rating is 250Vrms.

When discussing the use of the inductor, such as the 4922-36H, it is important to understand the concept of an inductor and how it works. An inductor works by creating an electromagnetic field using wire coils wound around a core made of ferrite, an alloy made from iron and other metals, or even air itself. When an electrical current passes through the wire coils, it creates a magnetic field, and this magnetic field is what causes the inductive effect of the inductor.

Fixed inductors are designed to be used in power supplies, which are DC [Direct Current] electronics, as part of a system\'s power line. This is because they act as a filter to reduce any high frequency noise that may be travelling along the power line, and thus, helping improve signal integrity. They also act as a choke, which is a device that blocks high frequency signals from travelling over certain lines. This is especially important in power supplies as electrical components often have a high frequency interference. It is for these reasons, that the use of fixed inductors, such as the 4922-36H, is essential in power supplies.

In conclusion, fixed inductors, such as the 4922-36H, are essential electrical components used in power supplies and other DC electronics systems. They work by creating an electromagnetic field when an electrical current is passed through them, allowing them to act as a filter and reduce any high frequency noise that may be travelling along the power lines and thus, helping improve signal integrity. Additionally, they also act as a choke which blocks high frequency signals from travelling over certain lines.
