Cog Npo Ceramic Capacitor

It is one of the most highly stable capacitors.

Cog npo ceramic capacitor. The ceramic capacitor gains its name from the fact that it uses ceramic materials for its dielectric. Common types include c0g np0 x7r y5v z5u although there are many more. Modern c0g np0 formulations contain neodymium samarium and other rare earth oxides. Avx eia class i c0g npo multilayer ceramic capacitors are one of the most stable capacitor dielectrics on the market.

C0g np0 ceramics offer one of the most stable capacitor dielectrics available. These capacitors offer significant advantages including a lifetime capacitance change of less than 0 1 which is one fifth of that shown by other dielectrics. What is a npo ceramic capacitor. It has very predictable temperature coefficients tcs and in general does not age with time.

Recently i took some time to study them realised how important they are and here are the details of what i learnt. Class i also known as npo temperature compensating capacitors. In this article i am explaining the differences between different ceramic capactior dielectric materials like x7r x5r x8r z5u y5v x7s c0g. I used to encounter these names x7r and x5r capacitors regularly but never bothered to look at what they are.

Npo ceramic capacitors are single layer ceramic capacitors made from a mixture of titanates. Within the ceramic capacitor family there are many forms of ceramic dielectric that are used. A npo ceramic capcitor is an ultrastable or temperature compensating capacitor.

Multilayer ceramic capacitors performance characteristics the eia standard for ceramic dielectric capacitors rs 198c divides into three classes. Cde multilayer ceramic capacitors are available in the three most popular temperature characteristics. Mouser offers inventory pricing datasheets for c0g np0 ceramic capacitors. C0g np0 is the most popular formulation of the temperature compensating eia class i ceramic materials.
