CMX-309 series
(1,000pcs/reel)
FEATURES:
Being of the miniature plastic SMD type and featuring high efficiency
in mounting, the CMX-309 is ideal for application to high-density
circuit boards.
As it incorporates a heat-resisting packaged cylinder-type crystal, it
features highly stable characteristics-high enough to permit reflow
soldering.
Can be mounted automatically because of the emboss taping used.
Low power CMOS IC.
Provided with output enable function.
APPLICATIONS:
Can be used for a wide range of applications including use in
communication equipment, AV equipment, OA equipment and
measuring instruments.
