A radial electrolytic capacitor cover has a green-black or black-gray color and two pins with different lengths as a means of polarity identification. (radial electrolytic capacitors) The shorter pin represents the cathode/negative terminal, while the longer pin displays the anode/positive terminal.

Figure 1. Schuko sockets. (Image source: Bran.) If you are referring to these sockets the dual earth pins give balance pressure on the plug which would otherwise be forced to upwards or downwards making insertion difficult and possibly affecting the contact of the L and N pins in their sockets.
There are two common geometries: axial and radial. Axial capacitors have one pin on each end of the cylinder, while in the radial geometry, both pins are located on the same end of the cylinder. Electrolytic capacitors have a larger …
A polarized component might have two, twenty, or even two-hundred pins, and each one has a unique function and/or position. If a polarized component was connected to a circuit incorrectly, at best it won''t work as intended. At worst, an incorrectly connected polarized component will smoke, spark, and be one very dead part.
The conventional method of mounting a decoupling capacitor is placing the vias next to the capacitor pads as shown in Figure 1. Figure 1. Image used courtesy of Electromagnetic Compatibility Engineering. For this case, a typical value for the total inductance from the mounting pads of the capacitor to the power-ground plane pair is about 1.1 nH.

Three-terminal Capacitor Structure With leaded two-terminal capacitors, the residual inductance is larger because the lead wires work as inductors. By making the three terminal structure,the residual inductance in series with capacitance become lower .Therefore the insertion loss is better than two terminal capacitors.

The value depends on the inductance of the PCB''s traces and the current peaks your IC excerts on the power supply. Most engineers will place 100nF X7R capacitors as close as possible to the IC''s power pins. One capacitor per power pin. A good IC pinout will have a ground pin next to each power pin, so you can keep the loop as short as possible.
The capacitor polarity is designated by the '' + '' symbol on one of the capacitor pins, meaning that the higher voltage should be connected there. What is even more interesting is that there are capacitors in which you can adjust to …

The two pins of a Polarized Capacitor have a clear positive and negative polarity, and the polarity of the two pins cannot be reversed when in use. Most common Polarized Capacitors are electrolytic capacitors, which can be divided into aluminum electrolytic capacitors and tantalum electrolytic capacitors according to different materials.
Here''s the other thing - 100nF (0.1uf) caps are common and you probably have a dozen on your board already. 200nF caps aren''t standard, 220nF is the next common size. Rule of thumb is one 100nF cap per pin, which would suggest two. But if the pins are proximal as somebody suggested, you could pop down a 220nF and call it a day.
The reason is two capacitors have a lower overall connection inductance and provide better high-frequency filtering to the rest of the power bus. Boards with closely-spaced power planes. ...

Variable capacitors, also known as tuning capacitors, have the ability to vary the capacitance value. They are commonly used in radio receivers, transmitters, and oscillators. Variable capacitors consist of two or more metal plates separated by an insulating material, and the capacitance value can be adjusted by rotating the plates.
There are two common geometries: axial and radial. Axial capacitors have one pin on each end of the cylinder, while in the radial geometry, both pins are located on the same end of the cylinder. Electrolytic capacitors have a larger capacitance than most other capacitor types, typically 1µF to 47mF.
45 MFD - the largest MFD number, A dual-run capacitor has two MFD ratings that are typically expressed in numbers separated by a slash, such as 5/40 or 5uf/40uf. 5 MFD - smaller number (5uf) is the smaller capacitor used to run the compressor/condenser unit''s cooling fan motor.

So if I have two grounds and one Vcc, should I have two capacitors hanging off the Vcc pin? No, one would be fine. The AtMega328 has one Vcc, one AVcc, and two grounds. So what do I do there?

If it actally has 3 separate terminals this its a dual capacitor, like in an ac unit one capacitor for the compressor one for the fan - in one enclosure. It will have two uf (micro farad) ratings, one for each.
A start capacitor typically has higher capacitance values than run capacitors, ranging from around 70 to 800 microfarads. It is also designed to handle higher voltage ratings, usually between 110 and 330 volts, depending on the specific …
A variable air capacitor (Figure (PageIndex{7})) has two sets of parallel plates. One set of plates is fixed (indicated as "stator"), and the other set of plates is attached to a shaft that can be rotated (indicated as "rotor"). By turning the shaft, the cross-sectional area in the overlap of the plates can be changed; therefore, the ...
Meanwhile, the decoupling capacitor releases the charges when the voltage drops to ensure the supply is stable. Often, you''ll need at least two coupling capacitors of different values to stabilize the voltage supplied to a component''s VDD pin. A capacitor in the range of 10 uF acts as a larger buffer to smoothen low-frequency fluctuations.
Polarized capacitors, such as electrolytic capacitors, have distinct positive and negative polarity on their two pins, which cannot be reversed during use. They typically filter out noise or interference signals in circuits, earning them the nickname "smooth filter capacitors."
The capacitors are classified into two types according to polarization: Polarized; Unpolarized; ... For example, electrolytic capacitors have their values printed on their body along with the pins. Disc capacitors have their values represented …
