Product Overview
This series of power inductors features a shielded structure with a closed magnetic circuit, offering strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. Designed for compact size and high current handling (up to 60A), these inductors maintain excellent temperature rise and saturation current characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder for low resistance and a robust structure, they ensure high product precision. They operate across a wide frequency range, extending above 5MHz, and are 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: Low-loss alloy powder
- Environmental Compliance: Halogen-free
- Operating Temperature Range: -40 to +125 (including self-temperature rise)
- Absolute Maximum Voltage: DC 25V (for most models), DC 75V (for some models)
