High-Current SMD Common Mode Inductor for Power Supply EMI Suppression Low Profile, for Space-Constrained Applications

The High-Current SMD Common Mode Inductor from Inductor Supplies is designed to tackle electromagnetic interference (EMI) in power supply circuits while delivering robust performance in space-constrained applications. Combining a low-profile design with high-current handling capabilities, this inductor effectively suppresses common mode noise, ensuring compliance with EMI standards and enhancing system reliability in demanding environments.

Features

• High Current Rating: Supports continuous currents up to 20 A, ideal for power-hungry applications such as DC-DC converters, motor drives, and industrial equipment.

• Space-Saving Design: Ultra-low profile (as thin as 2.5 mm) and compact SMD packages (1210, 1812) enable integration into dense PCB layouts without compromising performance.

• Effective EMI Suppression: High common mode impedance (up to 600Ω @ 10 MHz) minimizes noise propagation in differential lines, ensuring stable power delivery and reduced radiated emissions.

• Wide Temperature Range: Operates reliably from -55°C to +150°C, with excellent thermal stability for automotive, industrial, and high-reliability applications.

• Low DC Resistance (DCR): Advanced winding techniques reduce DCR (as low as 0.005Ω), minimizing power losses and heat generation.

• Robust Construction: Ferrite core with reinforced insulation and moisture-resistant coatings ensures durability and long-term performance in harsh conditions.

Applications

• EMI filtering in AC/DC and DC/DC power supplies

• Noise suppression for motor drives, inverters, and EV charging systems

• Automotive electronics (e.g., ADAS, infotainment, battery management)
