20、ent such as electronic products, uninterruptible power supplies, emergency lighting, engine starting, and power equipment. These energy storage capacitors, also known as “electric double layer capacitors”, ”ultracapacitors”, “double layer capacitors” or “supercapacitors” consist of either individual
21、 capacitors or multiple series and/or parallel connected capacitors with or without associated circuitry. 1.2 These requirements do not cover electrochemical capacitors for use in hazardous (Classied) locations. 2 Units of Measurement 2.1 Values stated without parentheses are the requirement. Values
22、 in parentheses are explanatory or approximate information. 3 Undated References 3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 4 Components 4.1 Except as indicated in 4.
23、2, a component of a product covered by this standard shall comply with the requirements for that component. 4.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by thi
24、s standard, or b) Is superseded by a requirement in this standard. 4.3 A component shall be used in accordance with its rating established for the intended conditions of use. 4.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are
25、intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions.

Current-limiting components include resistors, fuses and PTC thermistor type
29、 devices. 5.7 COMPONENT, TEMPERATURE LIMITING Any component used to restrict the degree of overheating during abnormal conditions. Temperature-limiting components include thermal protectors, thermal cutoffs, and PTC thermistor type devices. 5.7A ELECTROCHEMICAL CAPACITOR An electric energy storage d
30、evice where electrical charge is stored as a result of non-Faradaic processes at one or both of the electrodes. (A subset of electrochemical capacitors referred to as an asymmetric electrochemical capacitor have non-Faradaic processes at one electrode and Faradaic processes at the other electrode.)
31、The unique highly-porous electrode increases its surface area for holding charge resulting in much larger capacitance and energy density than other types of capacitors. Electrochemical capacitors differ from common electrolytic capacitors in that they store charge at the liquid-solid interface of th
32、e electrodes when a potential is applied rather than in a solid dielectric material covering the surfaces of the electrodes. Some other common names for an electrochemical capacitor are double layer capacitor , ultra-capacitor , electrochemical double layer capacitor , super-capacitor , and EDLC. 5.
