ACT200
The ACT200 is a miniature surface mount Watch Crystal whose low power consumption makes it
ideal for portable applications. It's size makes it suitable for high density circuit boards or applica-
tions where space is limited and the tape and reel packaging means that it is ideal for
automatic placement machines.
The heart of the device is a heat resistant cylinder type crystal which gives it high
stability characteristics sufficient to allow reflow soldering
