CM155

FEATURES:

^zBeing of the ultra-miniature SMD type, and thus featuring excellent

efficiency in mounting, the CM155 is ideal for application to high-

density circuit boards.

^zAs it incorporates a heat-resisting packaged cylinder-type crystal, it

features highly stable characteristics-high enough to permit reflow

soldering.

^zCan be mounted automatically because of the emboss taping used.

^zIts low power consumption makes it ideal for application to portable

equipment as well as high density, cellular phone designs.

APPLICATIONS:

^zPermits use as a clock source for communication equipment, AV

equipment, OA equipment, camera, cellular phones, pagers and

measuring instruments.
