Coin type Super Cap
Electric double layer capacitor EDLC or Super Cap, a type of product with a similar appearance to a button battery, we call it a button-type gold capacitor (Gold Capacitor). Super capacitors have extremely low leakage current and self-discharge characteristics, and are often used as clock memory circuits. (RTC) energy storage element is used,
The gold capacitor can provide a stable power supply to maintain the time and clock information that needs to be stored on the clock memory circuit (RTC). Through calculation, the standby time can be maintained for several minutes to several months, which is related to the power consumption of the circuit itself. .
Supercapacitors use the absorption and release reactions of ions to achieve the effect of cyclically storing electrical energy. This type of product has a higher cycle life, and is different from batteries that require periodic replacement. It is a part that can be repeatedly charged and discharged, and It has fast charge and discharge characteristics to maintain power, as well as the advantages of small size and a wider temperature range (-40 degrees to 85 degrees), which are indispensable components in the circuit.
