Due to the large size of the farad, capacitors typically have capacitance in microfarads (µF, 10 −6 F), nanofarads (nF, 10 −9 F), and picofarads (pF, 10 −12 F). A dielectric material is the insulating substance between the plates of a capacitor.
An ideal capacitor is characterized by a constant capacitance C, in farads in the SI system of units, defined as the ratio of the positive or negative charge Q on each conductor to the voltage V between them: A capacitance of one farad (F) means that one coulomb of charge on each conductor causes a voltage of one volt across the device.
Capacitors, together with resistors and inductors, belong to the group of passive components in electronic equipment. Small capacitors are used in electronic devices to couple signals between stages of amplifiers, as components of electric filters and tuned circuits, or as parts of power supply systems to smooth rectified current.
Thanks to their outstandingly high CV product, they are ideal for highly compact solutions in power electronics. The capacitors are designed for a maximum operating temperature of 105 °C; at a rated voltage of 450 V DC and maximum ripple current, they reach a useful life of 2000 h.
Voltage limited to about 100 V. Explodes when voltage, current, or slew rates are exceeded or under reverse voltage. Energy density typically tens to hundreds of times greater than conventional electrolytics. More comparable to batteries than to other capacitors. Large capacitance/volume ratio.
According to the number of values per decade, these were called the E3, E6, E12, E24 etc. series. The range of units used to specify capacitor values has expanded to include everything from pico- (pF), nano- (nF) and microfarad (μF) to farad (F). Millifarad and kilofarad are uncommon.

Larger capacitors are used for energy storage in such applications as strobe lights, as parts of some types of electric motors, or for power factor correction in AC power distribution systems. Standard capacitors have a fixed value of capacitance, but adjustable capacitors are frequently used in tuned circuits.
Electrolytic capacitors are known for high capacitance values, and they are essential in power supply filtering. They have polarity, requiring correct orientation in circuits, and are ideal for storing large amounts of …
Supercapacitors are electronic devices which are used to store extremely large amounts of electrical charge. They are also known as double-layer capacitors or ultracapacitors. Instead of using a conventional dielectric, supercapacitors use two mechanisms to store electrical energy: double-layer capacitance and pseudocapacitance. Double layer ...

En effet, tous les frigos grande capacité de notre comparatif font au minimum 70 cm de large, contre seulement 60 cm pour un modèle de gamme standard. Ces 10 cm supplémentaires permettent de gagner énormément de volume interne et donc d''augmenter drastiquement la capacité de l''appareil.
Most capacitors have designations printed on their bodies to indicate their electrical characteristics. Larger capacitors, such as electrolytic types usually display the capacitance as value with explicit unit, for example, 220 μF. For typographical reasons, some manufacturers print MF on capacitors to indicate microfarads (μF). [71]

One obvious difference between small and large capacitors is the capacitance value range: Tiny Capacitors. Moderate Capacitors. Large Capacitors. Higher capacitance requires larger physical size to store more charge. But it''s not all about just energy storage – construction and performance also diverge between capacitor scales.

Short-circuiting or mishandling a charged capacitor results in a rapid discharge, causing sparks, burns, or even an electric shock. In extreme cases, large capacitors deliver a potentially lethal shock. Both capacitors and batteries store electrical energy, but they do so in fundamentally different ways:

The size of a capacitor is critical because it directly impacts the performance of the circuit or device it is used in. A capacitor that is too large or too small can cause inefficiency, malfunction, or even permanent damage to sensitive equipment. Therefore, selecting the right capacitor size based on the application is essential.
