Fixed inductors are probably the most commonly used inductors in electronic circuits. Examples range from those mounted within a printed circuit board (PCB) to large-scale components for automotive applications. In particular, the LQP02HQ1N7B02L is a popular fixed inductor used in many applications.

The LQP02HQ1N7B02L is a shielded inductor with a ferrite core. It is rated at 2.2 uH with an operating frequency of 100 MHz. Its construction is unique because it is wound on a plastic bobbin, allowing for higher thermal efficiency compared to other inductors. The bobbin also provides mechanical stability, which is useful in the automotive sector.

The LQP02HQ1N7B02L is offered in various packages, including TO-220, SMD, and the NCG package. In the TO-220 package, the inductance is optimized for low losses while the SMD version has better EMC performance. The NCG package offers the best combination of features for high frequency operation. All packages are designed with low-leakage shielding and other components to minimize noise.

The LQP02HQ1N7B02L has many applications in the automotive and consumer electronics sectors. In the automotive industry, it is used for powertrain, electronic brake, power steering, and body electrical systems. In other sectors, it is used in power supplies, converters, and sound systems. Owing to its high-frequency response, the LQP02HQ1N7B02L can also be useful in communications, medical, and networking applications.

The working principle of fixed inductors is based on Faraday\'s law of induction, which states that a changing magnetic field induces a current in a conductor (i.e., the inductor). In practical terms, this means that when there is a change in voltage, the inductor will establish a magnetic field in response. This magnetic field in turn induces a voltage of its own, which is proportional to the rate of change of the original voltage.

The LQP02HQ1N7B02L is a fixed inductor that takes advantage of these principles in order to perform its function. It provides a set amount of inductance (in this case 2.2 uH) that remains constant regardless of the frequency of applied voltage. This allows it to behave as a low-pass filter, reducing the amount of high-frequency noise in a circuit. Alternatively, it can be wired in series and used as a resonator for oscillator circuits.

Overall, fixed inductors such as the LQP02HQ1N7B02L have a wide range of applications due to their ability to provide a steady magnetically-induced current, regardless of the voltage frequency. This makes them ideal for low-frequency power applications, as well as higher-frequency resonator applications. The LQP02HQ1N7B02L’s unique construction also offers superior thermal and mechanical stability over other inductors, making it a popular choice in the automotive sector.
