- A Ceramic Capacitor
is a capacitor constructed of alternating layers of metal and ceramic,
with the ceramic material acting as the dielectric. Depending on the
dielectric, whether Class 1 or Class 2, the degree of temperature/
capacity dependence varies. A ceramic capacitor often has (especially
the class 2) high dissipation factor, high frequency coefficient of
dissipation.
- A ceramic capacitor
is a two-terminal, non-polar device. The classical ceramic capacitor is
the "disc capacitor". This device pre-dates the transistor and was used
extensively in vacuum-tube equipment.
- Ceramic capacitors
come in various shapes and styles, including: disc, resin coated, with
through-hole leads ; multilayer rectangular block, surface mount; bare
leadless disc, sits in a slot in the PCB and is soldered in place, used
for UHF work; tube shape, not popular now.
- Manufacturing starts
with finely powdered base ceramic material that are pressed into dies
and fired at high temperatures. Individual capacitors may be cut from
large sheets of ceramic material.
- The capacitor
electrodes (i.e. the plates) are attached by screen printing a mixture
of silver, finely powdered glass, and a binder on both sides of the
disk, and firing the ceramic element again. This evaporates the binder,
and the melted glass binds the silver to the ceramic surface.
- Next, hairpin wires
are clipped onto the capacitor and it is dipped in solder. Once cooled
the capacitor is dipped into paint, marked, and the lower ends of the
hairpin cut off. Clearly the whole process lends itself to automation,
and dipped ceramic capacitors are very inexpensive. Capacitor
characteristics depend on the type of ceramic used.
- Parts manufacturers
have developed a highly integrated and high-performance semiconductor
integrated circuit. On the other hand, even in many electronic parts
such as a multilayer ceramic capacitor used in electronic equipment,
miniaturization and high capacity are being promoted and compact-size
products are increasingly being used. In chip multilayer ceramic
capacitors, the latest trend is subminiature products of less than 1005
size (1.0 × 0.5 mm).
- For the development
of subminiature multilayer ceramic capacitor, size is not only
miniaturized by the introduction of high-precision processing
technology, but also the approach for realizing compactness and higher
capacity is promoted by the introduction of high electrostatic capacity
technology.
-
High-voltage multilayer ceramic
capacitors are replacing aluminum electrolytic and film capacitors in
many applications where they offer improved performance.
-
Ceramic capacitor production in
India is almost non-existent, although there are a few niche
manufacturing companies promoted niche venture with output of Rs34
million.
-
Buyers can expect prices for
commodity multilayer ceramic capacitors (MLCC) to fall by as much as 5%
for the year, although leadtimes will stretch for some high-capacitance
ceramic capacitors. Prices for specialty devices will remain
stable.
-
The high-capacitance/low-voltage
market is driven by cell phones, laptop computers, digital cameras and
gaming consoles. To serve those industries, capacitor manufacturers cram
as much capacitance as possible into ever shrinking
packages.
