Citizen Crystals and Oscillators - CM155

CM155

FEATURES:
3,000pcs/reel
z Being of the ultra-miniature SMD type, and thus featuring excellent efficiency in mounting, the CM155 is ideal for application to highdensity circuit boards.
z As it incorporates a heat-resisting packaged cylinder-type crystal, it features highly stable characteristics-high enough to permit reflow soldering.
z Can be mounted automatically because of the emboss taping used.
z Its low power consumption makes it ideal for application to portable equipment as well as high density, cellular phone designs.

APPLICATIONS:
z Permits use as a clock source for communication equipment, AV equipment, OA equipment, camera, cellular phones, pagers and measuring instruments.
