Special ceramic chip capacitor for LED drive power supply 1812/1825/2220

High-voltage chip capacitors, also known as ceramic multilayer chip capacitors, are made using ceramic powder production technology. Inside, the precious metal palladium is used and the silver is plated on the ceramic as an electrode using a high-temperature sintering method. The product is divided into two materials: high-frequency porcelain () and low-frequency porcelain (R). Capacitors with small package size and high temperature resistance have good high-frequency performance and are used as circuit filter capacitors in highly stable oscillation circuits. R ceramic capacitors are limited to bypass or DC isolation in circuits operating at normal frequencies or in situations where stability and loss requirements are not high. Such capacitors should not be used in AC () pulse circuits because they are easily broken down by pulse voltages. Therefore, it is not recommended to be used in AC circuits. Chinese name

.Application scope
One type is temperature compensation type dielectric
Also known as the most stable electrical performance, which basically does not change with temperature, voltage, and time. It is an ultra-stable, low-loss capacitor material type. It is suitable for use in high-frequency, ultra-high frequency, and very high-frequency circuits that require high stability and reliability.
The second type is high dielectric constant type R dielectric
R is a ferroelectric medium and therefore can produce capacitors with a larger capacity than the dielectric. The performance of this kind of capacitor is relatively stable, and its unique performance changes are not significant with changes in temperature, voltage and time. It is a stable capacitor material type and is used in DC blocking, coupling, bypass, filter circuits and medium and high frequency circuits with high reliability requirements.
The third type is semiconductor type R dielectric
R has a higher dielectric constant and is often used to produce large-capacity capacitor products with larger specific volume and higher nominal capacity. However, its capacity stability is more sensitive than R capacity and loss to temperature, voltage and other test conditions. It is mainly used in oscillation, coupling, filtering and bypass circuits in electronic machines.
Advantages: small package size, stable quality, high insulation performance and high voltage resistance
Disadvantages: small capacity and easy to be broken down by pulse voltage. <
