Fixed inductors are passive two-terminal electronic components used to store energy in the form of magnetic fields. They are commonly used in applications such as voltage regulation, power filtering, current sensing and signal coupling. The LQP03TN56NH02D is a part of this category of components, and is an SMD power inductor designed for DC/DC converters, automotive, and telecommunication applications.

Applications and Features

The LQP03TN56NH02D is a general-purpose inductor ideally suited for DC/DC converters in applications ranging from commercial to automotive electronics. It offers a wide range of features for excellent performance in filtering, current sensing, voltage regulation, telecom, and industrial applications.

The LQP03TN56NH02D provides stable contact for excellent performance in high-peak current applications. Its low series inductance is perfect for applications requiring high-speed changes in current flow. It is also highly effective in applications containing high levels of radio frequency interference (RFI).

Additionally, the LQP03TN56NH02D is surface-mountable, making it ideal for applications where space is limited yet still requires reliable performance. Its tiny 3 mm x 3 mm size is perfect for portable consumer electronics or automotive projects. It also has a very low profile at only 2.8 mm height, making it a great choice for slim designs.

Working Principle

The working principle of the LQP03TN56NH02D is based on the electromagnetic property of inductance. In essence, inductance is the resistance encountered when electric current is changed with respect to time. This is due to the magnetic field produced by the current, which results in an opposing force. The LQP03TN56NH02D utilizes this principle to act as a filter or regulator in various applications.

When an alternating or pulsed current is passed through the inductor, the magnetic field induces a voltage opposite to the applied current, causing the current to lag behind the voltage. The high inductance of the LQP03TN56NH02D allows it to reduce the frequency of the current, blocking higher frequency signals and ensuring only a steady DC current passes through it.

The presence of an inductor in the path of a current also serves to reduce voltage peaks and improve the signal integrity of the power supply. The controlled current movement eliminates any chances of voltage variations or overshoot, regulated by the amount of energy that is stored and then released by the inductor.

The inductor also serves as a filter when connected to devices with high levels of radio frequency interference. The magnetic field generated by the inductor helps suppress higher frequency signals, allowing only the required signal to pass through.

Conclusion

The LQP03TN56NH02D is an excellent power inductor for automotive, telecommunications, consumer electronics, and industrial applications. Its low profile and compact size make it ideal for space-constrained designs, and its stable contact and inductance make it useful for filtering and current sensing.

The LQP03TN56NH02D uses the principle of inductance to reduce frequency of alternating current, block radio frequency interference and improve signal integrity. This makes it an indispensable component for any device requiring reliable performance in a small form factor.
