This product line features high-performance magnetic shielding structures designed for excellent electromagnetic interference (EMI) resistance and ultra-low buzzing. They offer a compact size with high current capabilities, reaching up to 60A, and maintain superior temperature rise and saturation current characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and a robust structure, these components ensure low resistance and high product precision. They operate across a wide frequency range, extending beyond 5MHz, and are manufactured as halogen-free, environmentally friendly products. Applications include PADs, laptops, desktops, servers, audio systems, networking, security devices, mobile phones, and smart home devices.
