Environmental Friendliness
The materials used in supercapacitors are environmentally friendly, free of heavy metals and other hazardous substances, and are highly recyclable, meeting the environmental requirements of modern electronic products.
Application Design Guide
When selecting an SDN series supercapacitor, engineers need to consider several factors. First, they should select the appropriate rated voltage based on the system's operating voltage requirements, and it is recommended to leave a certain design margin. For applications requiring high power output, it is necessary to calculate the maximum operating current and ensure that it does not exceed the product's rated value.
In system design, it is recommended to use an appropriate voltage balancing circuit, especially when using multiple capacitors in series, to ensure that each capacitor operates within its rated voltage range. Proper heat dissipation design also helps improve system reliability and extend service life.
For applications with long-term continuous operation, it is recommended to regularly monitor capacitor performance parameters to ensure the system is always in optimal operating condition. When used in high-temperature environments, appropriately reducing the operating voltage can extend product life.
