CERAMIC DISC CAPACITORS - MULTI LAYER CERAMIC DISC CAPACITORS
|
| |
 |
Multilayer Ceramic (MLC) Capacitor is a monolithic block of ceramic containing
two sets of offset, interleaved planar electrodes that extend to two opposite
surfaces of the ceramic dielectric. This simple structure requires a considerable
amount of sophistication, both in material and in manufacture, to produce
it in the quality quantities needed in today's electronic
equipments. Multilayer Ceramic Capacitors are available in a wide range
of characteristics. They are classified into two types : Class I are the
Temperature Compensating type and Class II are the General Purpose capacitors
with non-linear temperature co-efficients.
Class-I
Class-I capacitors or Temperature
Compensating capacitors are usually made from mixtures of Titanates
where Barium Titanate is normally not a major part of the mix. They
have predictable temperature coefficients and in general, do not have
an aging characteristic. Thus they are the most stable capacitor available.
Normally the T.C.s of Class - I Temperature Compensating capacitors
are NPO (Negative-Positive zero ppm/°C). These capacitors are used in
tuned circuits and filters where low loss and stability are necessary.
Class-II
General Purpose ceramic capacitors
are called Class - II capacitors and have become extremely popular because
of the high capacitance values available in very small size. Class -
II capacitors are “Ferro electric” and vary in capacitance
value under the influence of the environmental and electrical operating
conditions. Class - II capacitors are affected by temperature, Voltage
(both AC and DC), frequency and time. Temperature effects for Class
- II ceramic capacitors and are used in coupling and decoupling circuits
particularly in controlled temperature environment and in circuits where
change of capacitance with temperature is not of major importance.
POLY-AVX
manufacturing range includes Ultra-stable COG/1B i.e. NPO temperature
characteristic in Class I,
Stable X7R/2C1 and General-Purpose Y5V/2F4 temperature characteristics in
Class - II. |
