High-Current SMD Power Inductor for DC-DC Converters Small Size SMD Power Inductor, High Efficiency, Ultra-Low DCR

The High-Current SMD Power Inductor from Inductor Supplies is engineered to deliver exceptional efficiency and reliability in modern DC-DC converter designs. Combining ultra-low DC resistance (DCR), compact dimensions, and high current-handling capabilities, this inductor is optimized for power-intensive applications where space constraints and thermal performance are critical.

Features

• High Current Capacity: Supports continuous currents up to 30 A (package-dependent), making it ideal for high-power buck/boost converters, POL (point-of-load) modules, and industrial power systems.

• Ultra-Low DCR: Advanced winding technology minimizes DC resistance (as low as 0.003Ω), reducing conduction losses and improving overall converter efficiency.

• Compact SMD Design: Space-saving footprint (e.g., 1210, 1812) with a low-profile height (down to 2.0 mm) ensures seamless integration into densely packed PCB layouts.

• High Efficiency: Low core losses and high saturation current (up to 40 A) maintain stable performance under extreme load conditions.

• Robust Thermal Management: High-temperature-resistant core materials and construction ensure reliable operation from -55°C to +150°C, even in harsh environments.

• Shielded Design: Magnetic shielding minimizes electromagnetic interference (EMI) and crosstalk, enhancing system stability.
