These differences are too great to be able to be practically shown in a data sheet. However, these parameters can be critical when the resonators are used withmicrocontrollers. Even if two different resonators appear to have the same specification the typical values of these critical parameters can be considerably different. When enquiring about resonators for use with Imicricontrollers it is important to supply the make and part number of the IC to be used and/or the list of recommended resonators, if this is given. Please note that all parameters can not necessarily be specified in the same device Customer to specify : Frequency, Package Type and Size In line with our ongoing policy of product evolvement and improvement, the above specification may be subject to change without notice ISO9001:2000 Registered For quotations or further information please contact us at: 3 The Business Centre, Molly Millars Lane, Wokingham, Berkshire, RG41 2EY, UK Issue :7 C1r Date 07/03/2008 http://www.actcrystals.com
