COG (also known as NPO): Capacitors using this dielectric material are Class I capacitors, including standard and medium-to-high voltage COG products. These products offer stable electrical performance with virtually no variation due to temperature, voltage, or time. Suitable for low-loss, high-stability circuits such as filters, resonators, and timing circuits. X7R, X7S, X7T, X6R, X6S, X6T, X5R: Capacitors using this dielectric material are Class II capacitors, featuring high dielectric constant and greater capacitance than Class I capacitors, with relatively stable temperature characteristics. Suitable for circuits requiring wide capacitance range but less stringent stability requirements, such as DC blocking, coupling, bypass, and frequency discrimination circuits.

COG (or NP0) dielectric capacitors are suitable for filter, resonator, and timing circuits. X7R, X7S, X7T, X6R, X6S, X6T, X5R dielectric capacitors are suitable for DC blocking, coupling, bypass, and discriminator circuits.
