Product Description
Product Overview
These are high-performance power inductors designed for demanding applications. They feature a shielded structure for strong electromagnetic interference (EMI) resistance and ultra-low buzzing, enabling high-density mounting. The compact size belies their high current handling capability, reaching up to 60A, with excellent temperature rise and saturation current characteristics even in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and a robust structure, these inductors offer high product precision and low resistance. They operate across a wide frequency range, up to 5MHz and beyond, and are Halogen-free and environmentally friendly.
Product Attributes
- Material: Low-loss alloy powder
- Environmental Compliance: Halogen-free
- Construction: Shielded structure, closed magnetic circuit
Technical Specifications
Applications: PAD, Notebook Computers, Desktop Computers, Servers, Speakers, Network Communication, Security, Mobile Phones, Smart Home, etc.
