ACT90 & 91CSMX
The ACT90 & 91are miniature surface mount Watch Crystal whose low power
consumption makes them ideal for portable applications. Their size makes them
suitable for high density circuit boards or applications where space is limited and the
tape and reel packaging means that they are ideal for automatic placement machines.
The heart of the device is a heat resistant cylinder type crystal which gives them high
stability characteristics sufficient to allow reflow soldering.
