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 ...

Inside the box? Two capacitors as predicted. The repair was quick and then it was just a matter of putting it back together with a new cardboard box, some rivets, and new grommets.

The electric charge on these plates creates an electric field inside the capacitor. Since there is an electric field, there must also be a change in electric potential across the plates.

The inside of the capacitor is filled with an oil that helps to dissipate heat from the capacitor, and metal run capacitors have a plastic insulating liner that separates the metal from the oil. A ...

A capacitor contains two metal plates separated by a special insulating material called the “dielectric.” If you look inside the capacitor of a small motor, you would see that the metal plates are ...

Sponsored by Texas Instruments: Capacitors placed inside a buck-converter IC’s package coupled with proprietary Dual-Random Spread Spectrum (DRSS) technology can help minimize EMI and save board ...

When used as a power-ground core in a multi-layer PCB, the material becomes a decoupling capacitor inside the board. Further, the material allows designers to eliminate large numbers of decoupling ...
