FOJAN FCC0805X225K250FT

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 exhibit stable electrical performance with minimal variation over temperature, voltage, and 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 constants and greater capacitance than Class I capacitors, with relatively stable temperature characteristics. Suitable for circuits with wide capacitance ranges where high stability is not required, such as DC blocking, coupling, bypassing, and frequency discrimination circuits.

COG (or NP0) dielectric capacitors are suitable for low-loss, high-stability circuits such as filters, resonators, and timing circuits. X7R, X7S, X7T, X6R, X6S, X6T, X5R dielectric capacitors are suitable for circuits with wide capacitance ranges and less stringent stability requirements, such as DC blocking, coupling, bypassing, and frequency discrimination.
