Product Description
Product Overview
This product line features high-performance magnetic shielding structures designed for robust electromagnetic interference (EMI) resistance and ultra-low buzzing. Engineered for high-density mounting, these components offer compact sizes with high current capabilities up to 60A, maintaining excellent temperature rise and saturation characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and a durable, high-precision design, they operate across a wide frequency range, exceeding 5MHz. The products are also halogen-free and environmentally friendly. They are suitable for a broad range of applications including PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, and smart home devices.
