It is also suitable for various AC pulse circuit designs as well as pulse shaping designs. Another area in which this fixed inductor is commonly used is in the field of automotive electronics. Due to its low DC resistance and high Q values, the LQP02HQ1N7C02E can be used to meet the demands of devices operating in high frequency, high voltage, and high current environments. This type of inductor is commonly used in EMI filters, electronic fuel injection systems, and engine control systems.

Working Principle of the LQP02HQ1N7C02E Fixed Inductor

The LQP02HQ1N7C02E fixed inductor works based on the electrical principle of self-induced. Self-induced is a phenomenon in which an electrical current produces a magnetic field around it, which creates an opposing force on the current as it changes. When a current is applied to the inductor, the magnetic field created by the current flows through the core, generating a self-induced voltage. This opposing voltage opposes the current, thus limiting its change and maintaining the current at a steady-state.When a pulse signal is applied to the inductor, the induction process creates a voltage pulse which is higher than the applied pulse. The inductor will then search for the peak of the pulse and automatically charge or discharge itself to the peak voltage of the pulse signal. This is what allows the inductor to control the electric current in the circuit and maintain a steady current with the peak value of the pulse signal.

Conclusion

The LQP02HQ1N7C02E fixed inductor has a variety of applications, including power output circuits, voltage conversion circuits, motor control circuits, SMPS, switching power supplies, EMI filters, electronic fuel injection systems, and engine control systems. The inductor works based on the principle of self-induced voltage, with an opposing voltage induced in the core as a result of the current. It is capable of controlling the electric current in a circuit by charging or discharging itself to the peak voltage of the pulse signal, thus allowing for the current to be maintained at a steady-state. Overall, this fixed inductor provides many advantages to engineers in various aspects of electronics as well as automotive engineering, making it a reliable device for many types of applications.
