Important note when using Ceramic resonators with micro controllers
Some resonator parameters vary considerably with frequency and physical construction/size . 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 with micro controllers. 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 micro controllers 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
In line with our ongoing policy of product evolvement and improvement, the above specification may be subject to change without notice
