Description
Tel : Fax : email : 0044 (0)118 979 1238 0044 (0)118 979 1283 [email protected] 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.
