Wirewound Ferrite Beads SMB5H Family

As a precision wound ferrite bead, the SMB5H series offers enhanced EMI attenuation performance compared with conventional ferrite beads, making it suitable for demanding electronic environments.

What Is a Wound Ferrite Bead?

A wound ferrite bead combines a Ferrite Core with copper windings to create controlled impedance over a wide frequency range. Compared to non-wound ferrite beads, this structure provides:

• Higher impedance stability

• Improved current capability

• Better thermal performance under load

Because of these characteristics, using ferrite beads with wirewound construction is a common solution in advanced EMI Filter designs for industrial and consumer electronics.

SMB5H Series Key Features

• Wirewound Ferrite Construction
  Optimized winding structure ensures consistent impedance across high-frequency ranges.

• Effective EMI Suppression
  Reduces conducted and radiated noise in power and signal lines.

• Low DC Resistance
  Minimizes power loss and temperature rise during operation.

• High Reliability Design
  Suitable for continuous operation in harsh electrical environments.

• Compact Footprint
  Enables easy integration into space-constrained PCB layouts.

SMB5H beads are often used alongside ferrite bead inductor and Power Line Common Mode Choke components to form layered noise suppression solutions.

Using Ferrite Beads in Practical Applications

Using ferrite beads such as the SMB5H series is an effective method to suppress high-frequency noise without altering circuit functionality. Typical placement includes:

• Power input lines

• Signal lines near noise sources

• Interfaces between digital and analog circuits

When combined with Wirewound Ferrite Bead arrays or SMD Common Mode Chokes, SMB5H beads help systems meet EMC compliance requirements more efficiently.

Applications of SMB5H Wound Ferrite Beads

• Power supply input and output filtering

• Industrial control electronics

• Consumer electronics and appliances

• Communication equipment

• Automotive electronic modules

These wound ferrite solutions are widely used where stable EMI suppression is required without sacrificing current performance.
