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

efficiency in mounting, the CM155 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.

Its low power consumption makes it ideal for application to portable

equipment as well as high density, cellular phone designs.

Permits use as a clock source for communication equipment, AV

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

measuring instruments.
