A.Types of Dielectric Materials for Capacitors | |||||||
NPO: | It belongs to class 1 ceramic medium, and its electrical performance is the most stable, which is basically unchanged with the change of temperature, time and voltage. It is suitable for the occasions with strict requirements on stability and reliability, because of stable electrical performance and small DF value. Can work well in high frequency, very high frequency, very high frequency band. | ||||||
X7R: | It belongs to 2 kinds of ceramic media, and its electrical performance is the most stable. With the change of temperature and time, its characteristic changes are not obvious. It is suitable for the coupling, roadside, filtering circuit with high requirements and the medium frequency below 10 megabytes. | ||||||
Y5V: | It is a type 2 ceramic medium with high dielectric coefficient. It is used to produce capacitors with small volume and large capacity. Its capacity changes obviously with the temperature, but the cost is low | ||||||
