Product Overview
These power inductors are designed with a shielded structure, closed magnetic circuit, and strong electromagnetic interference resistance, ensuring ultra-low buzzing and high-density mounting capabilities. They offer a compact size with high current capacity, reaching up to 60A, and maintain excellent temperature rise and saturation current characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and low resistance, these inductors provide robust structure and high precision. They operate across a wide frequency range, extending beyond 5MHz, and are RoHS compliant (lead-free and environmentally friendly).
