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 applications 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
