Capacitor
SMD Multilayer Ceramic Capacitor
Capacitor selection:
The choice of dielectric is largely determined by the temperature stability required:
1) NPO (COG)
Ultra stable Class I dielectric, with predictable change of electrical properties
On temperature, voltage, frequency and time. Used in circuits requiring stable
Performance.
2) X7R
Stable Class II dielectric, with predictable change of properties with temperature,
Voltage, frequency and time. Used as blocking, coupling, by-passing and frequency
Discriminating elements. This dielectric is ferroelectric and offers higher
Capacitance ranges than class I.
3) Y5V (Z5U)
General purpose Class II dielectric 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
