6 Frequently Asked Questions about “The capacitor makes a popping sound”

Do capacitors make noise?

Don't worry about noise, capacitors don't generate noise except for leakage - which is low in your application. Current electrolytic capacitors have come a long way since your amplifier was built, plus designers have wised up to the high distortion they can create.

How do you know if a capacitor is squealing?

Essentially it's where gas is escaping through tiny holes in the capacitor and makes a “whistle” sound. You can usually visually spot this simply by looking at the top of the capacitor that's making the noise – if bulging or you can see a brown fluid then this is a true capacitor squeal.

Why is my capacitor venting through the legs?

As it is a capacitor, the inevitable conclusion is that the capacitor is venting through the legs. Not only do the caps appear to be unable to take the voltage, but the pressure safety feature at the top is failing to do its job. What the cause of that is is less easy to tell.

What is a capacitor squeal?

Confusingly the term capacitor squeal takes on more than one description and cause; we lift the lid on the entire subject. What is it? In short it's a high pitched squeal/whine/hiss/buzz noise emanating from a computer or electronic device.

Can a capacitor squeal cause a failure?

Capacitor squeal will almost certainly result in a failure if it already hasn't. It will be RMA time for this component. Coil whine is a different story but cannot always be solved, after all the acoustic noise is a by-product of something working normally; 1 – Leave it alone – If the device is new it may just mean the coil is simply “bedding in”.

Why does my power supply cap pop?

Capacitor popping, not sure why? In summary: Basically, when the cap pops, you'll hear a loud 'snap' and see a blue/white light show up on the negative terminal. It seems to happen when the voltage gets too high, and it's usually around the 700V range. It sounds like it might be connected to your power supply somehow, but I can't say for sure.
