Fixed Inductors are electronic components that store energy in the form of a magnetic field. The LQW18ASR22J0ZD is an excellent example of such an inductor. This device offers high inductance and low series resistance in a small package size.

The inductance value of the LQW18ASR22J0ZD is 18 nH, which is relatively high. The inductance is formed by winding a single layer of magnetically effective wire around a non-magnetic core. This core assists in concentrating the magnetic field and facilitates a high value inductance.

The series DC resistance of the LQW18ASR22J0ZD is defined at 2.2 Ω max. This low value of series DC resistance reduces power losses in the device, resulting in an efficient operation. The package size of the LQW18ASR22J0ZD is small, which allows for a high component density. This is an important feature when designing products where minimal board space is necessary.

The most common application of the LQW18ASR22J0ZD is in switching power supplies. It is used in these devices due to its high saturation current and low DC resistance. The high saturation current ensures that it can withstand the large inrush current caused by turning on capacitors. The low DC resistance enables the inductor to be used in conjunction with a small transformer to minimize power losses.

The working principle of the LQW18ASR22J0ZD is simple. It works by storing energy in the form of a magnetic field. When a current is passed through the device, it stores the energy in the form of a magnetic field. When the current is disconnected, the energy stored in the magnetic field is released and the device returns to its original form.

The LQW18ASR22J0ZD is a fixed inductor with excellent characteristics for switching power supplies. Its low series resistance and high inductance allow it to operate efficiently in this application. Furthermore, its small package size offers the benefits of high component density and minimal board space requirements.
