Fixed Inductors

A fixed inductor is an electronic passive device developed to create a fixed magnetic field. As current is passed through this device, it will store energy because of the magnetic field created. Fixed inductors are commonly used in filters, impedance matching applications and are the core components of many inductors. Fixed Inductors are composed of two components - a coil and a core - and the magnetic field produced by them can be controlled by changing either of these components.

The 3500-222K is a type of fixed inductor from Murata. It is commonly used in AC-DC power supplies, amplifiers, power converters and bridge drivers because of its high efficiency and low leakage current. Its operating temperature range is -40°C to 85°C.

The 3500-222K is an axial-lead, fixed inductor that can handle up to 2.7A of current. It has a rated inductance of 0.22µH ±20% and its DC resistance is only 0.06ohm. Its self-resonant frequency is 40MHz, and it has an operating temperature range of -40°C to 85°C.

The working principle of the 3500-222K is very simple. When a current passes through the inductor, the magnetic field created creates a “back EMF (electro-motive force)” which opposes the direction of the current flow. This opposing force causes the current to flow slower through the inductor, thereby reducing the total amount of current that can reach the load. As a result, the 3500-222K serves as a current-limiting device.

The 3500-222K is used in a wide variety of applications. Since its self-resonant frequency is 40MHz, it can be used for high-frequency applications such as switch-mode power supplies. It is also used for impedance matching in RF circuits and is generally used with other passive components to form a low-pass filter.

In addition, the 3500-222K is used as a suppressor in audio equipment. It can also be used in high-voltage circuits to reduce the current surge that may occur due to sudden voltage changes. It can also be used in flyback converters and computer motherboards.

The 3500-222K is a very versatile fixed inductor with a wide range of applications. Its small size, high efficiency and low leakage current make it ideal for many applications. It is an important component in many inductors, filters, and impedance matching applications and is a reliable device for many electronic applications.
