Product Overview
This series of inductors are designed for surface mounting, offering a compact and ultra-thin profile with high power handling, high saturation current, and low resistance. Featuring a magnetic-resin shielded structure, they significantly reduce buzz noise and magnetic leakage, providing strong anti-EMI performance. These inductors offer a rated current over 30% higher than traditional inductors of the same size and operate across a wide frequency range, reaching up to 5MHz. They are RoHS and Halogen-free compliant, making them an environmentally friendly choice for various applications including LED lighting, automotive systems, notebooks, desktop computers, servers, and graphics cards.
