| Citizen Crystals and Oscillators - CMX-309 series Page 1 of 2 CMX-309 series FEATURES: (1,000pcs/reel) 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.
