APPLICATIONS

USB line for personal computers and peripheral,

IEEE 1394 line for personal computers, DVC, STB.

LVDS, panel line for liquid display panels, graph card etc.

Packaging: T: Tape and Reel

Note: YAGEO will start to release lead-free common mode chokes of CMM Series which meet

SONY SS-00259’s criteria for lead-free product in Q2 of 2004, and the original P/N will

be added “-N” as identication. Ex. CMM21T-300M-N

FEATURES

Miniature SMD type common mode lter for fully automated assembly.

Wide Impedance range (30Ω~2200Ω) for noise suppression.

Excellent Solderability.

Operating temperature from -25˚C to 85˚C.

Based on YAGEO technical expertise, we have introduced a full series of common mode choke.
They are designed for excellent noise attenuation with a compact size for wide applications such as
USB line for personal computers and peripheral, IEEE 1394 line for personal computers, DVC, STB
and LVDS, panel line for liquid display panels, etc. We welcome you to contact us for requirement
of our standard series or custom design service.
