Power Bead Inductor

High current SMT power inductor

Product Overview

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 & Specifications

• 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:

1. Ferrite-core construction reducing electromagnetic interference by 40% vs. standard Transformers.

2. Optimized impedance curves maintaining >90% effectiveness up to 100MHz.

3. 20% higher current density than conventional Power Inductor designs.
   Integrate with our EMC Filter products for complete FCC/CE/VCCI compliance in noise-sensitive systems.

Typical Applications

1. Server/GPU Power Systems: Vcore regulators and multi-phase VRMs handling 28A+ continuous current.

2. Automotive Electronics: ADAS Sensor arrays and infotainment systems requiring -40°C operation.

3. Industrial Equipment: Motor drives and Sensor interfaces demanding 65A peak currents.

4. Telecom Infrastructure: Base station power supplies paired with EMC Filter networks.

5. Consumer Electronics: High-current laptop adapters and TV power modules.
