If it is used in a RC circuit the time constant of this could change. Will they still work? Should I let the guy know he sent me wrong ones? It really depends where in the circuit the capacitor is used, if it was in the signal path of the audio signal, sound could be different. I had a J capacitor go bad it looks like it blew up in a Sony audio system and ordered new ones from eBay but I received K instead. What is the 2J in the start? You need to replace it with a which is 4,7nF and a is a nF, which is times too large value for what you need. Here is a list of common capacitors and a scale between the different grades of the Farad SI unit.Īlso what is the wattage of the microwave transformer? Microwave oven capacitors are typically between 0,8 to 1,0 uF and a microwave oven transformer will be about to Watt depending on the model. Some small capacitance capacitors can be marked with a R between numbers, f. Judging by a capacitors size and type, you will quickly learn to determine if the value on the capacitor is given in pF, nF or uF. Looking at our capacitor we will see its marked J, this should be read as follows, 47 times the value that can be found in Table 1 corresponding to the 3rd number, in this case A second letter will be a temperature coefficient if its present.
