Specification

The ACT200 is an ultra miniature surface mount Watch Crystal with a low power consumption making it ideal for

portable applications. Its small footprint renders it suitable for high density circuit boards or applications where

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 cylinder type crystal which provides for high stability characteristics

sufficient to allow reflow soldering.
