High current SMT Power Inductor

The SMB series Power Bead Inductor delivers exceptional EMI suppression in ultra-compact SMD packages. Engineered for high-current applications up to 65A, these ferrite-core components outperform conventional Power Inductor solutions in noise attenuation. Their shielded construction provides stable impedance characteristics across extended temperature ranges (-55°C to +130°C), making them ideal for space-constrained power designs.

Key Features

• Ultra-High Current Handling: Supports up to 65A saturation current (Isat) with low DCR as low as 0.6mΩ.
• Wide Impedance Range: 25Ω to 100Ω at 100MHz (±25% tolerance).
• Robust Mechanical Design: Bottom hollow groove/flatness options for superior PCB mounting stability.
• Extended Thermal Performance: Operates from -55°C to +130°C with only 40°C temperature rise at rated Irms.
• Multi-Size Options: Compact footprints from 3.2×2.5mm to 9.4×3.1mm.
• Automation-Ready: Tape-and-reel packaging (400-7500pcs/reel) for high-volume assembly.

Technical Advantages

Unlike unshielded RF Inductor or Air Core Inductor components, these Power Bead Inductor solutions feature:

• Ferrite-core construction reducing electromagnetic interference by 40% vs. standard Transformers.
• Optimized impedance curves maintaining >90% effectiveness up to 100MHz.
• 20% higher current density than conventional Power Inductor designs.

Typical Applications

• Server/GPU Power Systems: Vcore regulators and multi-phase VRMs handling 28A+ continuous current.
• Automotive Electronics: ADAS Sensor arrays and infotainment systems requiring -40°C operation.
• Industrial Equipment: Motor drives and Sensor interfaces demanding 65A peak currents.
• Telecom Infrastructure: Base station power supplies paired with EMC Filter networks.
• Consumer Electronics: High-current laptop adapters and TV power modules.
