Product Overview
This product is a series of shielded power inductors designed for high-density mounting and excellent electromagnetic interference (EMI) suppression. Featuring a closed magnetic circuit, they offer ultra-low buzzing and are suitable for high-frequency and high-temperature environments. Constructed with low-loss alloy powder and robust structural integrity, these inductors provide high product accuracy, low resistance, and broad operating frequency ranges up to 5MHz and beyond. They are also halogen-free and environmentally friendly. Applications include PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, and smart home devices.
Product Attributes
- Material: Alloy powder
