>>Dielectric Type
The choice of dielectric is largely determined by the temperature stability required:
NPO (COG)
Ultra stable ClassⅠdielectric, with negligible dependence of electrical properties on temperature, voltage, frequency and time, Used in circuits requiring stable performance.
X7R
Stable Class Ⅱdielectric, with predictable change of properties with temperature, voltage, frequency and time. Used 5 Uas blocking, coupling, by-passing and frequency discriminating elements. This dielectric is ferroelectric and offers higher capacitance ranges than ClassⅠ.
Y5V(Z5U)
General purpose Class Ⅱdielectric with highest dielectric constant and greater variation of properties with temperature and test conditions. Very high capacitance per unit volume and suited for application as well as filtering, transient suppression blocking, and charge storage application.

Dielectric Classification: The dielectric is determinate by the stability of temp:
◆ NPO Class I dielectric, Ultra Stable. Suitable for circuits required stable performance
◆ X7R Class II dielectric, Ultra Stable. Suitable for circuits required general stable performance
◆ Y5V Class II dielectric, with higher dielectric constant, but stability is less than X7R
NPO Class I dielectric, Ultra Stable. Suitable for circuits required stable performance
X7R Class II dielectric, Ultra Stable. Suitable for circuits required general stable performance
