High-Current Integrated Molded Inductor for DC-DC Converters, Low DCR High-Reliability

The High-Current Integrated Molded Inductor from Inductor Supplies is engineered to meet the rigorous demands of modern DC-DC power conversion systems. Featuring a robust molded construction, ultra-low DC resistance (DCR), and exceptional reliability, this inductor delivers high efficiency, thermal stability, and compact integration for power-hungry applications in automotive, industrial, and next-generation electronics.

Features

• High Current Handling: Supports continuous currents up to 40 A and saturation currents up to 50 A, ideal for high-density power modules, POL (point-of-load) converters, and automotive powertrains.

• Ultra-Low DCR: Advanced integrated winding and molded core technology achieve DC resistance as low as 0.002Ω, minimizing conduction losses and maximizing power efficiency.

• Integrated Molded Design: Encapsulated construction enhances mechanical durability, moisture resistance, and thermal dissipation, ensuring stable performance in harsh environments.

• High Reliability: Engineered with high-temperature-resistant materials (rated for -55°C to +165°C) for long-term operation in automotive, industrial, and aerospace applications.

• EMI Suppression: Molded shielding reduces electromagnetic interference (EMI) and crosstalk, critical for noise-sensitive circuits.

• Compact Footprint: Space-saving SMD packages (e.g., 2525, 3636) with low-profile height (down to 3.5 mm) enable high-power designs in space-constrained layouts.
