My MacBook Air 2017 wouldn’t turn on, I could smell burning. Took the back off to find a burnt capacitor. Can’t seem to find them online to buy. NEb AV7
Telling us which motherboard model it is (820-XXXX) would allow us to give you a definitive answer. However, these are common capacitors on mac boards. The Code is NEb AV7. N represents the voltage (11V), Eb represents the manufacturing date code (not important) and AV7 represents the capacitance, in this case 62uF. This is not a standard, off the shelf component, as Apple has probably had them custom designed to their specifications. Look up the part number Augustine suggested and you should be able to order them online from Chinese vendors. Or you could purchase a donor board and transplant the component.
