Multilayer Metal alloy Ultra Large Current Bead-MPMZ Series

Overview

The MPMZ322520M large current series beads, packaging size is 3.2*2.5*2.0mm. Compared with ferrite beads this chip beads made of metal alloy have superior saturation characteristics, which is suitable for EMI noise suppression in power line of electronic devices.

Background

The impedance of ferrite beads due to the magnetic saturation properties when used in large bias DC circuit, which weakens EMI suppression ability. MPMZ series beads made of metal alloy can maintain decent impedance spectrum in power line, with low RDC this product is especially suitable for EMI suppression for power lines.

Features

  • Low profile and thin thickness, SMD type 
  • Superior saturation characteristics result from metal alloy material 
  • Low RDC, large rated current 
  • EMI suppression for dozens of MHz frequency

Applications

  • Noise suppression for power lines of communication devices, A/V devices, servers, PC and peripherals, etc.
