What are the silver top, round things I circled, and will they get very hot?

Must run cold if not near a heat generating component. ••• More options Share M Mark Tillotson Member Joined 2018 2021-10-16 11:03 pm #5 2021-10-16 11:03 pm #5 Electrolytics with a lot of ripple current can get somewhat warm, so I'd expect these might at high power levels. I'd expect to see more MLCC (ceramic) decoupling around the chips though (might be underneath). ••• More options Share Show hidden low quality content You must log in or register to reply here.
