Working Principle:

The PM75-390K-RC works based on the principle of electro-magnetic induction. The part consists of a bobbin that determines the inductance, as well as a core and magnetizable windings around the core. When an electrical current is passed through the windings, it creates an electro-magnetic field that generates a current in a similar direction. This creates an induced voltage, known as the back EMF, that opposes the applied current, resulting in the part\'s low-loss and high-dc-rail performance.The PM75-390K-RC is also designed to meet RoHS requirements. RoHS is an electronic product manufacturing standard that requires the component to be free of certain hazardous substances, which this part achieves by employing numerous lead-free components and materials. In conclusion, the PM75-390K-RC is an excellent fixed inductor option for high frequency power amplifier applications, telecommunication systems, power management systems, and a variety of other electronic designs. It is characterized by a low-loss and high-dc-rail performance, and its compliance with RoHS standards makes it suitable for use in environmentally friendly designs.
