ACT200
The
ACT200
is a miniature surface mount Watch Crystal whose low power consumption makes it
ideal for portable applications. It鈥檚 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
s ta b i l i t y characteristics sufficient to allow reflow soldering
