Fixed inductors are components found in many electrical and electronic circuits. They are used to store energy in the form of a magnetic field, as well as to shape current flow. In this article, we will look at the application field and working principle of the LQH43NN270K03L fixed inductor.

LQH43NN270K03L is a type of Common Mode Choke Coil. This device is a ferrite core coil made of high electromagnetic performance promoting ferrite material and is used for noise suppression in the frequency of 10MHz to 150MHz. It is most suitable for differential signal lines and is used for RFIC, Connector, Hub, Switch, PCB and other applications. It has excellent heat resistance and humidity resistance and is RoHS compliant. It is available in various dimensions such as 7.3 x 7.3 x 4.4mm and 12.0 x 12.0 x 8.4mm.

The working principle of the LQH43NN270K03L is based on the principle of inductance. Inductance is the phenomenon of storing electrical energy as magnetic energy. Coils acts as inductors for ac waves due to the self inductance. A coil that is wound around a ferrite core behaves just like an inductor, only with a much higher inductance due to the magnetic field of the ferrite core. The magnetic field of the ferrite core interacts with the applied ac voltage, resulting in the current in the coil changing its direction in regular intervals as the applied voltage changes direction.

These periodic reversals in current through the coil will ensure that the voltage across the coil is in an opposite direction to the applied voltage, and thus the applied voltage is canceled out. The LQH43NN270K03L Common Mode Choke Coil is designed to perform this task, and it is used to reduce the noise to a certain level. It also reduces the amount of EMI emitted from the device, ensuring compliance with necessary industry standards.

As a result of its excellent resistance to heat and humidity, the LQH43NN270K03L fixed inductor is widely used for noise suppression. It is commonly employed in many electronic devices such as RFICs, Connector, Hub, Switch, and in Printed Circuit Boards. It is also widely used for board level power line filters and data line input/output circuit applications.

In conclusion, the LQH43NN270K03L fixed inductor is a useful component for electronics engineers. Due to its excellent performance characteristics, it is used in a wide variety of electronic and electrical applications. Its application field and working principle were explored in this article, and it was found that this inductor is most suitable for suppressing noise in the 10MHz to 150MHz frequency range, and is also widely employed in board level power line filters and data line input/output circuit applications.
