Aluminum electrolytic capacitors from China suppliers come in 5 to 600V.

Aluminum electrolytic capacitor makers in China offer lead, chip, screw and snap-in types. Releases come in 0.1µF to 3F and 5 to 600V versions to suit various requirements. These have a typical operating temperature of -40 to 85 or 105 C. There are models that support 125 or 130 C. Nantong Sancon Electronic Technology Corp.'s selection includes products with up to 820F.

By electrolyte, the options are nonsolid and solid. The first uses the liquid form, while the latter adopts organic polymers such as polythiolene and polyprole.

Suppliers categorize the components by application as well. There are consumer, industrial and special capacitors. The third includes products for the military and aeronautics sectors.

Electrode foils are the key material, accounting for 30 to 60 percent of production cost. The rest of the inputs are electrolyte, electrolytic paper, sealing rubber, lead terminals and aluminum case.

Makers obtain the first locally. The major providers include Guangdong Dongyangguang, Xinjiang Joinworld, Guangxi Hezhou Guidong, Jiangsu Zhonglian and Nantong South Light. For electrolyte, the top source is Shenzhen Capchem.

Electrolytic paper comes mainly from NKK of Japan, and domestic companies Zhejiang Kan and Minfeng Special Paper. The other materials are purchased in the mainland.

Despite rising labor outlay, manufacturers are reducing prices to attract more orders amid intense competition.

Here is a selection of aluminum electrolytic capacitors from China:
