MHz RANGE CRYSTAL UNITS (PLASTIC SURFACE MOUNT TYPE) CM309S Life-size DIMENSIONS: (UNIT=mm) | _ 12.5MAX _ | | | S: | a 1z = | HU | 0.8 0.8 Electrode Arrang a = ement min ae: = CITIZEN. (1,000pcs/reel) MFEATURES: Being of the miniature SMD type and featuring high efficiency in mounting, the CM309S is ideal for application to high-density circuit boards. * As it incorporates a heat-resisting packaged cylin- der-type crystal, this crystal makes best use of the superb characteristic AT-cut crystals have, and per- mits reflow soldering. Enables automatic mounting, due to the adoption of the emboss taping packaging. M APPLICATIONS: Can be used for a wide range of applications includ- ing use in communication equipment, AV equip- ment, OA equipment and measuring instruments. m@ RECOMMENDED SOLDERING PATTERN: (UNIT=mm) 7.6 1.6 05 teh) Conditions een ROY fo_|__S.OMINZ~S4MINZ (FUNC), 27MNZ~7OMNZ (Std OT) __| Please contact us for chaages in renuenes.| Frequency tolerance Af/fo ~ +30ppm or +50ppm | | At 25C | Frequency vs. Temperature characteristics | Af/fo | +50ppm (+30ppm) 10C~+60C Operating temperature range Torr | 40C~+85C _ Storage temperature range Tste 5C~+125C | Equivalent series resistance Ri See drawing At 25C Load capacitance Ci 16.0pF TYP.
