WE-MPSB - Multilayer Power Suppression Bead

Huge Peak, Strong Bead!

Multilayer Power Suppression Bead

The WE-MPSB series is the world’s first ferrite bead that specifies how it performs under high current transients. This unique bead protects and extends the life of your application.
It features an ultra-low RDC which delivers the lowest self-heating in its class at high currents. The WE-MPSB is ideal for DC/DC applications requiring high efficiency.
WE-MPSB optimizes high current vs. RDC performance with up to 75 % RDC reduction in comparison to similar components while maintaining a high impedance over a wide frequency range.

Component Selection with REDEXPERT

The fastest way to determine the best component is by using the Pulse Designer in REDEXPERT to meet your peak current requirements based on inrush current amplitude and pulse length. As a registered user, you can set the slider in the diagram to 170 MHz and then directly add to the grid the resistance values for each component. You can even specify a descending sort, where the part with the highest resistance is at the top.

Further advantages of REDEXPERT:

  • The world’s most accurate AC loss model
  • Filter settings for over 20 electrical and mechanical parameters
  • Inductor simulation and selection for DC/DC converters
  • Ability to compare inductance/current and temperature rise/DC current using interactive measurement curves
  • Available in seven languages
  • Online platform based on measured values
  • Order free samples directly
  • Direct access to product datasheets
  • Comfortable and clear component selection
