Fixed inductors, also known as choke coils, are mainly used in electronic circuit of current-limiting and blocking, sway frequency or for noise suppression to protect and control circuits. The LQP02TN22NH02D fixed inductors are basically one type of the standard choke coils. The LQP02TN22NH02D can be considered as an electronic component comes in relatively small package but offers good performance in various working conditions.

The inductance value of LQP02TN22NH02D fixed inductors ranges from 1.2uH to 3.3uH with maximum dc current ranged from 0.100A to 0.300A. The Q factor is 50 at 1KHz. The rated voltage is 30Vdc and working temperature is -40°C to +125°C. The package style is a shallow magnetic shield type and with surface mount. The product comes with Halogen-free material and Pb-free finish, suitable for RoHS application.

The application of LQP02TN22NH02D fixed inductors covers a wide field, from consumer electronics to transportation and networking. It can be used in power supplies to reduce AC noise from line, eliminate spurious noise, efficiency enhancement, as well as voltage stability/adjustment. When mounted in power switching circuits, it works as a power choke which blocks the dc currents in the power supply and keeps the electric signals within the pass bands from being distorted. In some transportation related applications, the LQP02TN22NH02D can be used as a signal choke to reduce the high frequency noise from sources like RADAR and/or IR systems to increase the signals to noise ration and improve the performance of the system. In networking application, it can also be used as noise suppressor along with bypass capacitor to protect the system structure and control circuits from disturbances.

The working principle of LQP02TN22NH02D fixed inductors is to create magnetic field when there is current passing through the coil. The higher the winding numbers of the coil, the higher voltage density will be produced and higher inductance will be achieved. Thus, the choke coil is able to limit the high frequency impulse current by the conversion of magnetic field energy into heat. The current-limiting and blocking characteristics of the fixed inductor protect and control the functioning of various circuits, included the power, signal and AGC circuits.

Compared to the other coil products, the LQP02TN22NH02D fixed inductors offer better performance and reliability with reduced power losses and higher insulation integrity. It is also designed to handle higher current passing through the coils with low energy losses. As the result, the LQP02TN22NH02D inductors are becoming popular to be used in a variety of electronic circuitries and widely applied in consumer electronic apparels, power supplies, switching circuits, electrical shunt and telecommunications hi-tech products.
