MP Posted April 1, 2007 Report Share Posted April 1, 2007 They are certainly not ceramics. With a closer look by enlarging the picture, I see these three are not all the same capacitor type. The 39 pf has a different appearance. The 100 nf caps are tantalum and the 39 pf cap is a silver mica. In looking at the schematic this also makes sense due to the purpose of each.MP Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 1, 2007 Report Share Posted April 1, 2007 Pick a capacitor type, any capacitor type.The 39pf capacitor is a ceramic, not an old silver mica. Quote Link to comment Share on other sites More sharing options...
MP Posted April 2, 2007 Report Share Posted April 2, 2007 Use what you want, but your picture doesn't even agree with your statement. Sure looks like the more squared silver mica than the very small round ceramic to me. ;DAll fun aside, the silver mica will be better. I use them in microcontroller crystal applications where more precision of frequency is required than what a ceramic will give. Silver Mica is not an "old" cap. They are widely used in everyday electronics.MP Quote Link to comment Share on other sites More sharing options...
ante Posted April 7, 2007 Report Share Posted April 7, 2007 The appearance of capacitors differs between manufacturers and these might very well be ceramics. When repairing many different types of equipment one encounters various brands and learns to see the differences and similarities. Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 8, 2007 Report Share Posted April 8, 2007 Why doesn't somebody fix this confusing project so that the schematic, the pcb layout and the parts list agree????????????????????????????????????????????????????????????????????Or else just dump this project.
