Ceramic capacitors
The choice of dielectric is largely determined by the temperature stability required:
Npo (cog) ultra stable classdielectric, with negligible dependence of electrical properties on temperature, voltage, frequency and time, used in circuits requiring stable performance.
X7r stable class =dielectric, 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 class.
Y5v(z5u) general purpose class =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,
Wide capacitance, voltage and tolerance range Industry standard sizes Tape and reel available for auto placement Various lead spacing available
Multilayer ceramic capacitors Wide capacitance, temperature , voltage and tolerance range; industry sizes; tape and reel available for auto placement; a lot of leads type available.
Multilayer ceramic chip capacitors Dielectric type - the choice of dielectric is largely determined by the temperature stability required: Npo: ultra stable class i dielectric, with predictable change of electrical properties on temperature, voltage, frequency and time. Used in circuits requiring stable performance. X7r: stable class ii dielectric, with predictable change of preperties 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. Y5v: general purpose class ii dielectric with highest dielectric constant and greater variation of properties with (z5u) temperature and test conditions. Very high capacitance per unit volume and suited for bypass and coupling application as well as filtering, transient supression blocking, and charge storage application.
