Fixed inductors are electrical components used in electronic circuit designs to add inductance in order to regulate, modify or filter current flows. Fixed inductors are widely used in audio equipment, radio transmission, television, computers, gaming consoles and many other applications where a continuous and fixed amount of inductance is needed. The ETQ-P3WR82WFN is an example of a fixed inductor from the ETQ company.

The ETQ-P3WR82WFN is a 12mm x 17.5mm fixed inductor with a 10uH IDC rating. It has an impedance of 30mΩ DC max at 1.0MHz and 25A max IDC current rating. The product is made with a high-grade ferrite core with high-temperature epoxy encapsulation for long-lasting dependability. Its low DCR and high current ratings make it ideal for applications such as basic audio, DC-DC converters, power supplies, automotive audio, LED drivers, and many other applications.

The working principle of the ETQ-P3WR82WFN inductor is based on a physical phenomenon called "electromagnetic induction". It works by generating a current in a coil when placed in a changing magnetic field, or when having a current flow pass through it. According to Faraday’s Law of Electromagnetic Induction, a magnetic field around a current carrying wire will induce a voltage along the wire, thus creating an induced current flow in the conductor.

The main advantages of using this kind of inductor are its robust design, low DCR, high current capabilities and excellent frequency response. These advantages are particularly useful in applications such as automotive electronics, power supplies, LED drivers, switching power supplies, audiovisual equipment and many more. Furthermore, the ETQ-P3WR82WFN inductor is RoHS compliant and carries UL, CQC and PSE certifications.

In conclusion, the ETQ-P3WR82WFN is an example of a fixed inductor. It is a 12mm x 17.5mm inductor with a 10uH IDC rating, and is made with a high-grade ferrite core. It has a low DCR and high current ratings which make it ideal for applications such as basic audio, DC-DC converters, power supplies, automotive audio, LED drivers and many other applications. The working principle of this inductor is based on electromagnetic induction, which creates an induced current flow in a coil when placed in a changing magnetic field. This inductor has a number of advantages which make it suitable for many applications, and is RoHS compliant as well as carrying UL, CQC and PSE certifications.
