Pardon me if this is a re-send. Digi-Key sells a ZTT series 4 mHz ceramic resonator (through hole) with built in caps for $0.68 ($.45 in 100s). Does anyone have experience with these? Do they seem to work as well with (say) PIC16F84A or 16F628 as the much acclaimed (and characterized for PIC) Murata devices. The reason I ask is that I don't know where to get the Murata parts nor what to order, Digi-Key is easy. They also have a surface mount ECS-SRA-B series. Same question?? -- Looking forward: Alan Shinn Experience the beginnings of microscopy.
