◆ FEATURES ◆ APPLICATIONS
z Multi-line EMI Suppression
M-series chip arrays contain four ferrite
beads in a single package. This
compact design makes the M-series
perfect for EMI suppression on
multiple-lines.
z High Density Packaging
M-series chip arrays have a compact
package design that is ideal for high density
packaging.
● Multi-frequency Applications
M-series chip arrays are available in
A-type and B-type.The A-type chip
arrays are designed for lower frequency
applications.The B-type chip arrays are
designed for high frequency
applications.
M-series chip beads can be used in a variety of
electronics including:
• Computers
• Printers
• Modems
• Hard Drives
• CD-ROMs
• Monitor
• Mainboards
• Televisions
◆ OPERATING TEMPERATURE: -40 ~ 85℃
