China manufacturers of metallized film capacitors are strengthening the category, spurred by the forecast 15 percent annual sales growth in coming years. While most continue to enhance the performance of mature types, major players venture into the development of SMDDiscrete miniature capacitors which are packaged without leads and fastened directly to foil patterns. units and variants for new-energy industries.
Under efforts to follow the miniaturization trend in application products, large manufacturers such as Xiamen Faratronic are introducing SMDDiscrete miniature capacitors which are packaged without leads and fastened directly to foil patterns. kinds. The supplier offers polyethylene naphtalate or PEN-based stackedMultiple capacitor elements stacked in multi-unit arrangement to provide bulk capacitance and lower ESR.Multiple capacitor elements stackedMultiple capacitor elements stacked in multi-unit arrangement to provide bulk capacitance and lower ESR. in multi-unit arrangement to provide bulk capacitance and lower ESR. models in sizes of 1812, 2220, 2824, 4030 5040 and 6054. These units are mainly adopted in XDSL products, base stations, multiplexers, and automotive safetyClass X capacitors are used in “across-the-line” applications where their failure would not lead to electric shock. Class X safety caps are used between the “live” wires carrying the incoming AC current. In this position, a capacitor failure should not cause any electrical shock hazards, rather, a capacitor failure “between-the-lines” would usually cause a fuse or circuit breaker to open. and engine control systems, radios, navigation systems and air-conditioning. HID lamps, electronic ballasts, DC-DC converters, LCDs and plasma display panels are the other uses.
SMDDiscrete miniature capacitors which are packaged without leads and fastened directly to foil patterns. configurations account for less than 10 percent of China’s metallized film capacitor output. Most come from foreign-invested businesses there. Only a few local companies turn out such types due to the high manufacturing technology and as demand is still low.
China suppliers are eyeing the growing “green” segments, encompassing solar and wind power, and electric and hybrid vehicles. Xiamen Faratronic invested $18 million in 2012 to increase annual capacity to 300 million μFUnit of capacitance. The basic unit of a measure of a capacitor. A capacitor charged to 1 volt with a charge of 1 coulombA coulomb is the unit of electric charge. It is named after Charles-Augustin de Coulomb.1 coulomb is the amount of electric charge transported by a current of 1 ampere in 1 second. It can also be defined in terms of capacitance and voltage, where one coulomb is defined as one farad of capacitance times one volt of electric potential difference. would have a capacitance of 1 farad. 1 microF = .000001 Farads. for these applications in 2H14. It is expecting the venture to bolster revenue by more than 25 percent in coming years.
For most manufacturers, lighting and home appliances remain the key markets, accounting for about 60 percent of output and more than 60 percent of sales. Guangdong Fengming Electronic Tech. Co. Ltd and Xiamen Faratronic derive the bulk of their businesses from them.
Complementing product initiatives is manufacturing capacity expansion as suppliers also take advantage of healthy demand from the telecom, power supplies, industrial control and automotive electronics sectors. Guangdong Fengming plans to move to a new factory to boost current capability, which is 2 million units per day. Shenzhen Shanrui Electronics Co. Ltd has two facilities with a combined area surpassing 5,500sqm, and can handle 100 million units monthly. The latter expects 10 percent higher revenue by year-end.
To enhance competitiveness in mainstream applications, makers concentrate on improving the product’s self-healing properties by adopting 6μm and below metallized film. They will release more such models in the months ahead. Most versions in the current selection use 7μm material, with the choices respectively ranging from 2.8 to 20μm and 0.9 to 23μm in the PP and polyester-based subcategories. Companies also emphasize high stability and insulation resistanceThe ratio of the applied Voltage to the total current between two electrodes in contact with a specific insulator. A measure of the resistance to a DC current flow through the capacitor under steady state conditions. Values for film and ceramic capacitorsThe main differences between ceramic dielectricThe insulating material between the plates of the capacitor. The material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. The material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. types are the temperature coefficient of capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive., and the dielectricThe insulating material between the plates of the capacitor.

In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. loss.Ceramic capacitors tend to have low inductance because of their small size. are usually expressed in megohm-microfarads for a given design and dielectricThe insulating material between the plates of the capacitor.

The material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields.. The actual resistance of the capacitor is obtained by dividing the megohm-microfarads by the capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference.

Metallized variants dominate mainland China’s supply of film capacitors. They have about 70 percent turnout share at Shenzhen Topmay Electronic Co. Ltd, over 90 percent at Shenzhen Shanrui and 100 percent at Guangdong Fengming.
The mainland is the largest manufacturing hub for the line, producing more than 40 percent of the global total. About 150 suppliers make up the pool, of which 80 percent are locally owned. Xiamen Faratronic, Nantong Jianghai and Anhui Tongfeng are among the key ones. The international players there include Panasonic, Kemet, TDK, Vishay and those from Taiwan.
About half of the makers gather in the province of Guangdong. The rest are in Fujian, Anhui, Jiangsu and Zhejiang provinces.
