WHY, I have used 10.000s of such with no problems. Now, I must say, I buy only known brand. Of course, of course!! This was addressed to Kiran, who has problems to get reliable parts in Mumbai. Of course can SMD quartzes be used. But take a good one. Nevertheless, if you have a look into the datasheets, you will find the equivalent series resistance being higher. Good micros will properly work with good SMD quartzes! Kai Klaas |
