Hello,
I need to replace a surface mount capacitor that has failed on my boiler PCB. The problem is I have no idea what value it is. It tests o/c Can anyone help please?
small value capacitors will show as o/c if you use a resistance meter. Borrow a capacitance meter to measure the value (once you've removed it from the PCB)
Thank you Dougy, well, the capacitor looks a tad 'fried' as the pcb was exposed to a brief erroneous short if that makes sense. All the others show a level of impedance that varies as they 'fill up'. I take your point about testing it off the board, not sure I can get a cap tester though. is there any way to identify it's value?
