Chip tantalum capacitors
Solid tantalum chip capacitors are designed and manufactured with the demanding requirements of surface mount technology in mind. There are a, b, c, d, e, s six case codes. They have lower esr comparing with the dipped tantalum capacitors. The product is compatible with automatic pick and place equipment. Suitable for military equipment and computer fceil telephone and other electronic products.
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.
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,
