Aluminum electrolytic capacitors are electronic components composed of two parallel metal plates separated by an insulating material, referred to as a dielectric. The metal plates, or conductors, can either be an anode or cathode, depending on the type of capacitor, and the dielectric consists of two layers. The first, an insulating aluminum oxide layer, is formed by anodizing the aluminum plate. The second layer is usually a paper, plastic or other solid dielectric material.

The EEU-FM1C680 is a type of aluminum electrolytic capacitor from the Panasonic Electronic Components line. It has a voltage rating of 16 volts and a maximum capacitance value of 680µF. It is a snap-in type capacitor, which means it is designed to snap into a given space on a PCB (printed circuit board) for secure mounting. Its size is 13.5mm x 20mm.

The EEU-FM1C680 has two primary application fields: decoupling and filtering. In decoupling, the capacitor is used to reduce the noise produced by switching and rectifier circuits. It stores enough energy to continue to provide power to gate circuits and other digital circuits even while the main power supply is changing. In filtering, it is used to filter out high frequency AC signals while passing the DC signals. This is possible because, while normal capacitors pass both AC and DC signals, aluminum electrolytic capacitors offer a very high impedance to AC signals and a much lower AC resistance to DC signals.

The capacitance value of an EEU-FM1C680, like all capacitors, is dependent on its working principle. Capacitance is determined by the ratio of charge stored to the instantaneous potential difference across the plates. Since the EEU-FM1C680 has a voltage rating of 16V and a maximum capacitance of 680µF, the potential difference created by the charge stored in the capacitor must be 16V. The amount of charge is determined by its max capacitance of 680µF. Since 6.31 x 10^(-6) coulombs are stored for every farad of capacitance, the charge stored in the EEU-FM1C680 must be 4.30 coulombs.

As a snap-in type aluminum electrolytic capacitor, the EEU-FM1C680 is specifically designed to be mounted on a printed circuit board. It is secured in place by two snap-in pins, which must be inserted into the two mounting holes on the PCB. Care must be taken not to bend or press too firmly on the pins during their insertion, as this could damage the pins and result in a poor connection. Once the pins are properly inserted, they can be secured by soldering them onto the board.

The EEU-FM1C680 is a versatile aluminum electrolytic capacitor with two main applications in decoupling and filtering. Its voltage rating of 16V and maximum capacitance of 680µF determine its potential difference and stored charge, respectively. Its two snap-in pins make it an ideal capacitor for mounting on a PCB, and its compact size makes it suitable for most circuits. As such, the EEU-FM1C680 is often utilized in a variety of projects, from consumer electronics to industrial machinery.
