Dear Valuable customer,

Good news for you :)

Most of other suppliers are on holiday for Chinese New year, but to give prompt reply and service, our sales department still work during Spring Festival.
If you have any inquiries, orders, or urgent demands, please feel free to contact our sales.

And part of our workers will work overtime for two specially busy production lines:
X2 Metallized Polypropylene Film Capacitors and Metallized Polyester Film Capacitors, if you have demands, hope we can give you fast support.

Welcome you to contact our sales team, our sales will feel very warm because of you ^_^.

jb capacitors wish you Merry Christmas & Happy New year!

Take this opportunity, recommend you one of our most strong series capacitor--JFB series.
JFB series is a Dipped Metallized Polyester Film capacitors,
pitch size from 10mm to 27.5mm, capacitance from 0.01uF to 10uF, voltage from 100V to 630V

This series crossed Panasonic ECQE, Vishay MKT368, Konek MKT 68, K73-17....in China called CL21..
widely used in electronic ballast, CFL, switch power supply... very popular, big demand in the market due to competitive prices.

A capacitor is a passive electronic component that stores energy in the form of an electrostatic field.  In its simplest form, a capacitor consists of two conducting plates separated by an insulating material called the dielectric. Capacitance is directly proportional to the surface areas of the plates, and is inversely proportional to the plates' separation.

Capacitance also depends on the dielectric constant of the dielectric material separating the plates.

The standard units of Capacitance,

farad: F
microfarad: µF (1 µF = 10-6 F)
nanofarad: nF (1 nF = 10-9 F)
picofarad: pF (1 pF = 10-12 F)

For any good capacitors, welcome to find us.jb can help you in this regards.

Film Capacitors are distinguished by their extreme reliability. They are principally used in power supplies for telecom equipment, domestic appliances and entertainment electronics. Energy-saving and environmentally friendly lighting would be inconceivable without Film Capacitors. They are also essential to high-speed Internet access.

Along with the high integration of semiconductor devices, the miniaturization of their components has also advanced. For a dynamic random access memory (DRAM), a high-capacity capacitor with small size is required. Ferroelectric thin film capacitors with extremely large relative permittivity have been developed for this purpose. In film capacitors, the dielectric in such film capacitors comprises a plastic film. The electrodes comprise conductive metal areas. These metal areas are either thin conductor films or conductor layers vapor-deposited onto the plastic film. Thin-film capacitor devices generally comprise a substrate and a lower electrode, a dielectric layer, and an upper layer which are deposited on the substrate in that order. Thin-film capacitors also have a semiconductor substrate functioning as a lower electrode and have a dielectric layer and an upper layer which are deposited on the semiconductor substrate in that order in some cases.
