Introduction: What is Super capacitors ?

Super capacitors, also known as electrochemical capacitors (electric double layer capacitors short as EDLC), gold capacitors, farad capacitors.

EDLC which can hold more than million times capacitance of regular capacitors is the future green energy storage device. Depending on the capacitance, EDLC is able to be variously applied. Less than 1F grade EDLC backs up the data and maintains RTC(Real Time Clock) built in the circuit as an auxiliary power system when a power supply of the application such as mobile phones, MP3 players, and Audio, VCR, etc is stopped. 10F ~ 100F and thousands of F grade EDLC are being used in large hybrid cars, UPS,EMU, copier requiring an instant high power, EDLC is also being gradually expanded to power unit like solar, wind, and environment-friendly renewable energy resources as an essential component. 

Most suppliers from China is postponing production schedule after CNY holiday this year.

The low leakage and high capacity of tantalum capacitors favors their use in sample and hold circuits to achieve long hold duration, and some long duration timing circuits where precise timing is not critical. They are also often used for power supply rail decoupling in parallel with film or ceramic capacitors with low ESR and reactance at high frequency. Tantalum capacitors can replace aluminum electrolytic capacitors in situations where the external environment or dense component packing results in a sustained hot internal environment and where high reliability is important. Equipment such as medical electronics and space equipment that require high quality and reliability make use of tantalum capacitors.

Low-voltage tantalum capacitors are commonly used in large numbers for power supply filtering on computer motherboards and in peripherals due to their small size and long-term reliability.
