Usage Tips:Feature: Charging speed is quick. Small environmental pollution. Charge and discharge lines are simple. The volume is small,but the capacity is big. Low temperature and low internal resistance and low leakage current. With super long life which is up to more than 100 thousand times, and is more than 10-100 times the battery. The capacity is bigger than the same volume electrolytic capacity about 30~40 times. High power density, is 10~100 times of the battery, even reach about 10kw/kg. Specification: Dielectric material:Super farad Shape:Cylindrical Color:black Capacitance: 10 Farad Max voltage: 2.7V ESR:60m permissible voltage:2.5V Lead wire type:Same direction Allowable deviation:-20~40% Frequency:low frequency Application scope:low voltage Applications: CPU intelligent home appliance,meter,tax control machine,controller,air conditioning,recorder,MP3,car o,telephone,solar lights,real-time clock etc. Power supply of small power devices,such as:intelligent water meter,gas meter,disinfection cabinet,electronic door locks,solar equipment,digital set-top boxes,toys,etc. Electric starting system,with the battery used in various internal combustion engines such as for cars,tanks,for diesel locomotives,can effectively protect the battery and prolong its service life,reduce the power loss with capacity.
