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.
