Fixed Inductors

Fixed inductors are components that produce a continuous magnetic field through the use of a coil. This magnetic field can be used to store energy in a circuit or to transfer electrical signals between two components. The 1812-331G is a type of fixed inductor that is designed for use in various applications and can perform a variety of functions.

Applications

The 1812-331G is suitable for use in power supply modules, DC-DC converters, mounting units, electronic circuits, and signal transformation circuits. It has a wide range of applications due to its resistance to EMF, high temperature durability, and high efficiency. It is also suitable for use in motor control, over-voltage protection, and signal coupling applications.

Construction

The 1812-331G is constructed with a ferrite core and a copper winding. The core is designed with an air gap to produce a high inductance. The copper winding is insulated with enameled wire. The 1812-331G has a maximum operating temperature of +125 degrees Celsius and a thermal resistance of 1.5 degrees Celsius/W.

Working Principle

The working principle of a fixed inductor is based on the movement of electrons in an electric current. When a current passes through the coil of the inductor, it forms an electromagnetic field that is reactant to the current. This field creates a self-inductance, which is the amount of inductance in the coil. The induced current in the circuit is proportional to the rate of change of the current flowing through the coil. This means that the induced current in the circuit is larger when the rate of change of the current flowing through the coil is higher.

Advantages of the 1812-331G

The 1812-331G has a high efficiency and a wide operating temperature range. It is also highly resistant to electromagnetic interference, which makes it suitable for use in electronic circuits. The 1812-331G has a high saturation current, which allows it to function efficiently even at high current levels. Finally, it has a low level of electromagnetic radiation, which makes it suitable for applications that require low levels of electromagnetic radiation.In summary, the 1812-331G is a type of fixed inductor that is suitable for a wide range of applications. It is constructed with a ferrite core and a copper winding and it works on the principle of movement of electrons in an electric current. The 1812-331G has a wide operating temperature range, a high efficiency, a high saturation current, and a low level of electromagnetic radiation, which make it suitable for various applications.
