Product Description
Product Overview
These high-performance inductors feature a shielded structure with a closed magnetic circuit, offering strong electromagnetic interference (EMI) resistance and ultra-low buzzing for high-density mounting. They provide 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 featuring low resistance, these inductors are robust and precise. They operate across a wide frequency range, extending beyond 5MHz, and are RoHS compliant (halogen-free). Ideal for applications such as PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, and smart home devices.
Product Attributes
- Material: Alloy powder
- Environmental Compliance: Halogen-free
