ACT200A - Prefered Product.
The
ACT200A
is a miniature SMD Watch Crystal with excellent low power consumption, making it ideal for
portable applications. 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.
