Its small footprint makes it suitable for high density circuit boards and applications where PCB space is limited. The tape and reel packaging means that it is ideal for automatic placement machines (loose product is also available). The heart of the device is a heat resistant precision tuning fork, cylinder type, crystal which provides for good stability characteristics, sufficient to allow reflow soldering. Applications include: Clock, Sub Clock, Small Communications Devices, Microcomputer etc. Specification Parameter Nominal Frequency Frequency Tolerance Frequency v Temp Characteristics Turnover Temperature Freq.
