These aluminum electrolytic capacitors are common residents on circuit boards. We may have cut one open to satisfy our curiosity of what’s inside, but that doesn’t necessarily mean we ...

An aluminium electrolytic capacitor is more like this The basic equivalent circuit for a capacitor has a series resistance and inductance, which covers the connecting leads and any internal tabs ...

Recently a member of TDK-Lambda’s technical marketing team experienced first-hand just how much influence small diameter electrolytic capacitors can have on long-term power supply reliability.
