Description :

The NPO (COG) is a high Q, low K temperature compensating type of dielectric with stable electrical properties under varying voltage, temperature, frequency and time. It's suitable for circuits that require low lost, as well as timing and tuning applications.
The X7R has moderate K value and is temperature stable. It shows moderate change in electrical properties under changing temperature, voltage, and frequency. It's suitable for by-passing, coupling, and frequency discrimination circuits applications.
The Y5V has high K value. Its electrical properties vary considerably under changing voltage, temperature, and time. It's suitable for all general purpose applications where high capacitance values are required, and are ideal for room temperature applications with low DC bias.
