1331R-223H

Fixed Inductors

Fixed inductors are passive electronic components which store energy in the form of magnetic field that can be built up when a current is passed through them. Fixed inductors are widely used in a variety of electronic circuits, and are often found in application-specific integrated circuits (ASICs), electronic amplifiers, signal conditioning amplifiers, motor control circuits, and other applications where efficient conversion of AC to DC power is needed.

1331R-223H Application Field and Working Principle

The 1331R-223H fixed inductor is a well-known product from Murata Electronics, which combines a high-frequency transformer, RF inductor, and an inductor/transistor in one miniaturized package. This inductor has a height of 1.59mm (typical) and a width of 1.4mm (typical). The operating temperature range is -55˚C to +85˚C and can endure a surge current of up to 6.7A.

The 1331R-223H works as a choke, and the core material used for this inductor is iron. This type of core offers high reliability, as it reduces the chances of failure, insulation breakage, and other issues that can occur with weaker cores.

The 1331R-223H also offers a high self-resonance frequency, low DCR, and high current-carrying capability. This means that the 1331R-223H can handle high-frequency signals, and is well suited for high-speed digital circuits. Due to its small size, it can be used on PCBs, and can also be used in portable devices such as cell phones, computers, etc.

The 1331R-223H is suitable for high-frequency applications such as TV tuners, PC cards, portable radios, video audio cards, and so on. This inductor can be used in various circuits such as pulse-width-modulated motor control, synchronous rectification, and voltage-controlled oscillators.

The 1331R-223H works on electromagnetic principles. When a current passes through it, a magnetic field is generated which stores energy in it. The magnetic field is generated due to the current and can be changed by altering the current going through the inductor. When the current is stopped, the stored energy in the field is released, and can be used to drive the load. In this way, fixed inductors can convert alternating current into direct current.

The 1331R-223H can be used in many applications due to its high performance and low cost. It is commonly used in AC/DC converters, power supply units, and other electronic devices which require an inductor. With its high self-resonance frequency and low DCR, it is also suitable for high-speed digital circuits, which require speed and efficiency.
