High Current Shielded Power Inductors
Product Overview:
These high-current shielded power inductors are designed for demanding applications requiring high efficiency and reliability. Featuring a closed magnetic circuit, they offer excellent electromagnetic interference (EMI) suppression and ultra-low audible noise, enabling high-density mounting. Their compact size belies a high current capability, extending up to 60A, while maintaining superior temperature rise and saturation current characteristics even in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and featuring a robust structure, these inductors ensure high product accuracy and low resistance. They operate across a wide frequency range, up to 5MHz and beyond, and are RoHS compliant and halogen-free.
Applications:
- PADs
- Notebook Computers
- Desktop Computers
- Servers
- Audio Systems
- Networking Equipment
- Security Systems
- Mobile Phones
- Smart Home Devices
