Appears to be glue leaking capacitors tend to have a white powdery substance not always on them.

Leaking capacitor or glue. Often seen as a brown tinged stain on the pcb. The glue itself is harmless. Electrolyte usually leaks out through the capacitors top vents which your capacitors dont have or its leads and dries to a light colored powder.

That is non conductive adhesive used to hold the electrolytic capacitors and other components in place during assembly of the printed circuit board pcb and to provide rigidity to those same capacitors during end use. Unless the capacitor leaking looks like glue. 2 points 1 year ago.

The glue looks like the capacitor is leaking. A dark brown or black crust up the side of a capacitor is invariably glue not electrolyte. Capacitors usually leak by bulging at the top but can sometimes leak out the bottom.

Leaky capacitors or glue. New comments cannot be posted and votes cannot be cast. As above not sure how i missed your answer.

The leaked electrolyte can be confused with thick elastic glue sometimes used to secure the capacitors against shock. They are just some sort of glueepoxyhard silicone to secure the components from vibration effect. Those are not electrolyte leakage from the electrolytic capacitors.

Electrolyte is also brownish in colour google bad caps and take a look but a cap doesnt have to leak or bulge to be bad. That is the typical look of glue that is used to stop large capacitors from vibrating and breaking their leads off. This thread is archived.

Some components tends to be loosen easily this is why the manufacturer have to use those compound to secure it. Original poster 1 point 1 year ago. However the electrolyte is pretty thin and will make a small puddle or show an obvious runoff if the device isnt perfectly level.
