Category
This magnetic component is a compact inductor/transformer designed for filtering and energy management in small electronic devices. It operates effectively in the -40℃ to +125℃ range with low losses and meets RoHS requirements. Typical applications include power supply filtering for IoT devices and EV charging interfaces. Engineers should ensure proper soldering techniques and thermal management due to its limited current handling capabilities. The product offers cost efficiency and quick availability but lacks advanced frequency response and high current specifications compared to industrial-grade alternatives.
