Key Features and Technical Specifications

The SMB5H Series is engineered to deliver high impedance at targeted frequencies while maintaining low DC resistance (DCR). This makes it particularly effective in suppressing electromagnetic interference without compromising signal integrity or power efficiency.

Electrical Characteristics:

• High Impedance Range: Up to 1000Ω @ 100MHz (model-dependent)
• Low DCR: Minimizes power loss and heat generation
• Rated Current: Supports high-current applications without saturation
• Operating Temperature: -55°C to +125°C
• Frequency Response: Optimized for 10MHz–1GHz range

Structural Advantages:

• 5-Hole Design: Increases effective permeability and impedance by maximizing surface area and magnetic path control.
• Compact SMD Package: Easy to place automatically, suitable for high-density PCB designs.
• RoHS Compliant: Ensures environmental and safety standards are met.

Fun Fact: The five-hole configuration isn’t just for show—it significantly reduces EMI noise by distributing magnetic flux more effectively than conventional beads.
