OEM Super Capacitor Factories - High Voltage Ceramic Disc Capacitors 20KV Blue – JEC

Features

High withstand voltage, low loss
High insulation resistance and long service life

High-voltage ceramic capacitors mainly refer to capacitors with an AC working voltage of more than 10KV, or ceramic capacitors with a DC working voltage of more than 40KV.
High-voltage ceramic capacitors used in high-power and high-voltage fields are required to have the characteristics of small size, high withstand voltage and good frequency characteristics.

FAQ
Q: What does the 104 marked on the ceramic capacitor stand for?
A: The number 104 on the capacitor means that its capacitance is 100nF, or 0.1uF. A number such as 104 or 103 marked on the capacitor is the value indicating the capacitance of the capacitor. The first two digits are significant digits, the third digit is a multiple, and the calculated unit is pF.
Q: How long is the life of a capacitor in general?
A: The lifespan of capacitor is generally several years.
For example, a capacitor with a rated maximum temperature of 85°C has a lifespan of 1000 hours at an ambient temperature of 85°C, and when the ambient temperature drops to 60°C, the life can be extended to about 10,000 hours, and when the ambient temperature drops to 40°C, the life can be extended to up to about 80,000 hours.

From the perspective of the service life of the capacitor, the service life of high voltage ceramic capacitors is longer. The lifespan of film capacitors is three to two years, while high-voltage ceramic capacitors are different. High-voltage ceramic capacitors are generally designed for a 20-year service life, and are generally guaranteed to be used for at least 10 years.
