The multilayer ceramic capacitor has a many-layered dielectric. These capacitors are small in size, and have good temperature and frequency characteristics.

Square wave signals used in digital circuits can have a comparatively high frequency component included.This capacitor is used to bypass the high frequency to ground.

Ceramic capacitors have become the preeminent, general purpose capacitor, especially in SMT chip devices where their low cost makes them especially attractive.  With the emergence of thinner-dielectric, multilayer units with rated voltages of less than 10 V capacitance values in the hundreds of microfarads have become available.  This intrudes on the traditional, high-capacitance province of aluminum electrolytic capacitors.

Ceramic capacitors are not polarized and therefore can be used in AC applications.  The low DF and high capacitance stability of Class 1 and 2 are especially suited to AC and RF applications.

There are many types of Capacitors in Suntan Technology Company Limited’s stock.This Capacitors are widely used in many areas in this Computer Times.Suntan Ceramic Capacitor arte wide applicable in computer, data processor, telecommunication, industrial control, and instrumentation equipments, etc. And built by superior moisture and shock resistant epoxy coating, can be supplied in both bulk or tape and reel package for automatic insertion in printed circuit board.

Ceramic capacitors are available now in three main types although other styles are available:

• leaded disc ceramic capacitors for through hole mounting which are resin coated
• multilayer surface mount chip ceramic capacitors
• Specialist microwave bare leadless disc ceramic capacitors that are designed to sit in a slot in the PCB and are soldered in place

Although it is possible to obtain other types of ceramic capacitor, these are the main types that can be found today. Of these the surface mount variety is used in the greatest quantities by far because of the manufacturing methods used these days for electronic equipment.

When measured at room temperature (25°C ± 5°C) and at a frequency of 0.1 to 1 Megahertz, the minimum capacitance shall not be greater than that specified at minimum setting with a +10% tolerance and the maximum capacitance shall not be less than that specified maximum setting with a - 10% tolerance.

A well constructed multilayer ceramic capacitor chip is extremely reliable and, for all practical purposes, has no wearout mechanism when used within the maximum voltage and temperature ratings. Most failures occur as a result of mechanical or thermal damage during mounting on the board, or during subsequent testing.

Capacitor failure may also be induced by sustained operation at voltages that exceed the rated DC voltage, voltage spikes or transients that exceed the dielectric's voltage capability, sustained operation at temperatures above the maximum rated temperature, internal defects, or excessive temperature rise due to power dissipation.

As with any practical device, multilayer ceramic capacitors also possess an inherent, although low, failure rate when operated within rated conditions.The primary failure mode is by short-circuit or low insulation.

resistance, resulting from cracks or from dielectric breakdown at a defect site. Suntan monitors reliability with a periodic sampling program for selected values.

Multilayer ceramic capacitors are available in a variety of physical sizes and configurations, including leaded devices and surface mounted chips. Leaded styles include molded and conformally coated parts with axial and radial leads. However, the basic capacitor element is similar for all styles. It is called a chip and consists of formulated dielectric materials which have been cast into thin layers, interspersed with metal electrodes alternately exposed on opposite edges of the laminated structure. The entire structure is fired at high temperature to produce a monolithic block which provides high capacitance values in a small physical volume. After firing, conductive terminations are applied to opposite ends of the chip to make contact with the exposed electrodes. Termination materials and methods vary depending on the intended use.

Suntan TS17 Axial Multilayer Ceramic Capacitor, it can be made 50VDC and 100VDC, from 100pF to 1uF. The leads can be bended for mounting purpose.

Multilayer (mono) Axial & Radial Features:

Wide application in computer, data processor, telecommunication, Industrial control, and instrumentation equipments, etc.

Built by superior moisture and shock resistant epoxy coating, can be supplied in both bulk or tape and reel package for automatic insertion in printed circuit board.

SMD ceramic capacitors are shaped in the form of a rectangular block or cuboid. The capacitor itself consists of the ceramic dielectric in which a number of interleaved precious metal electrodes are contained. This structure gives rise to a high capacitance per unit volume. The inner electrodes are connected to the two terminations, either by silver palladium (AgPd) alloy in the ratio 65 : 35, or silver dipped with a barrier layer of plated nickel and finally covered with a layer of plated tin (NiSn).

Suntan supply many kinds of Ceramic Capacitors such as High Voltage Ceramic Capacitors, Multilayer Ceramic Capacitors, Ceramic Disc Capacitors, Mini Type Ceramic Capacitors etc.

The ceramic SMD capacitors form the majority of SMD capacitors that are used and manufactured. They are normally contained in the same type of packages used for resistors.

• 1812 - 4.6 mm ~ 3.0 mm (0.18" ~ 0.12")
• 1206 - 3.0 mm ~ 1.5 mm (0.12" ~ 0.06")
• 0805 - 2.0 mm ~ 1.3 mm (0.08"~ 0.05")
• 0603 - 1.5 mm ~ 0.8 mm (0.06"~ 0.03")

Suntan Multilayer Ceramic Capacitor - SMD - TS18 has four types of packages used for resistors. In Suntan’s website www.suntan.com.hk there is a Dimensions of Multilayer Ceramic Capacitor - SMD - TS18 as followings:

MLCC capacitors are marvels of modern material science. Manufacturing MLCC capacitors is considerably more complicated than manufacturing dipped ceramic capacitors. First, the base ceramic material is mixed with a binder and fashioned into thin sheets. Electrodes are painted onto one side of the sheets using a paint that consists of a liquid binder with fine metal particles in suspension. The metals that are used include gold, palladium, platinum, and silver alloys. The reason for using these metals is that when the base ceramic is fired, oxygen is required for the ceramic proper to form.

Once the ink is dry, the sheets are stacked on top of each other. The painted electrodes are arranged so that alternate electrodes exit from opposite ends. The top- and bottom-most layers do not have painted electrodes. The laminated layers are then compressed and fired, which sinters them into one monolithic structure.

Next, the ends are terminated, often using silver. For leaded capacitors, wires are attached, and finally the capacitor is encapsulated in plastic and marked. In the case of chip capacitors, the silver end terminations are covered with tin to aid soldering. The whole capacitor may be covered with lacquer.
