SMD Inductor SMB

Product Overview

The SMB Series SMD Inductor delivers exceptional power handling in compact surface-mount packages, designed for applications requiring ultra-high currents up to 65A.

These shielded ferrite-core components outperform conventional Power Inductor solutions with 40% lower DCR and superior thermal management.

Their robust construction ensures stable performance across extreme temperatures (-55°C to +130°C), making them ideal for space-constrained power designs.

Key Specifications

• Ultra-High Current Capacity: Up to 65A saturation current (Isat) and 30A Irms with DCR as low as 0.8mΩ.
• Wide Inductance Range: 300nH to 1.6μH (±10-15% tolerance) for versatile circuit design.
• Compact Footprints: Miniature sizes from 3.1×2.5mm to 10×10mm with optimized thermal pads.
• Enhanced Thermal Resilience: Operates from -55°C to +130°C (SMB1007B) with only 40°C temperature rise at rated current.
• High-Frequency Performance: Suitable for applications up to 100MHz, outperforming many RF Inductor components in power density.

Technical Advantages

Unlike traditional Transformers, these SMD Inductor solutions feature:

• Shielded construction reducing EMI radiation by 30% vs. unshielded alternatives.
• Ferrite cores minimizing losses in Power Converter systems operating at 5MHz.
• 50% higher current density than standard Power Inductor designs.
  For EMI-sensitive applications, pair with our EMC Filter products to achieve full CE/FCC/VCCI compliance.
