Hi Duke. 5% less than 4.8μF is 4.56μF. I'm guessing what you are saying is the tolerance of +-5% brings it close to the 4.5μF I was asking about. So if I use the 4.5μF, then we could ask what is 5% less than 4.5μF...but we won't. Your point is well taken. I don't think I'll worry about the 0.3μF difference. Thanks for your response.
