Product Description
Product Overview
These high-performance shielded inductors are designed for demanding applications requiring excellent electromagnetic interference (EMI) suppression and low acoustic noise. Featuring a compact design with high current capabilities up to 60A, they maintain superior temperature rise and saturation characteristics even in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and a robust structure, these inductors offer high precision and low resistance. They are suitable for a wide operating frequency range, extending beyond 5MHz, and are RoHS compliant (halogen-free). Ideal for use in power supplies for PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, and smart home devices.
Product Attributes
- Material: Low-loss alloy powder
- Compliance: Halogen-free
- Shielding: Magnetic shielding structure, closed magnetic circuit
