jb Supercapactors Replace Rechargeable Batteries in Transportation, Industry, New Energy Batteries

Supercapacitors used in high-power power supplies and large-scale industrial power supplies. Now we have found their use in products of various sizes, especially portable devices. Supercapacitors are well-known for their capacitance values up to thousands of farads and fast charging and discharging rates.

Due to the ability to store large amounts of electrical energy for a long time, the supercapacitor behaves more like a battery than a standard capacitor. In fact, as technology advances, they will replace rechargeable batteries in many products, from computers, digital cameras, mobile phones to other handheld devices.

Today,Many countries in the world are actively carrying out research and development related to supercapacitors. The main manufacturers are: MAXWELL and Ioxus in the United States, EL NA and PANASONIC in Japan, LS Mtron and Vina Technology in South Korea, and ECOND in Russia. jb Capacitors Company of China brand, it’s a nice choose:

 - 5.5V Standard Coin Type Super Capacitors
JGM - 5.5V 7.5V Combined Type Super Capacitors
JGY - 5V 7.5V Combined Type Super Capacitors
JGZ - 2.7V 3V Low ESR Radial Snap in Screw Type Super Capacitors

JYC – High Voltage Ceramic Radial Type Disc Capacitors
We designs and manufacture high quality Ultra-High Voltage Ceramic Capacitors Radial-Leaded Single Layer Disc (low loss type) Capacitors with blue coating epoxy resin, custom design radial lead disc ceramic capacitors as well as a variety of standard and custom High Voltage & High Capacitance value Ceramic Capacitors.

JYM - Multilayer (Mono) Ceramic Capacitors
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. Our JYM - Multilayer (Mono) Ceramic Capacitors, it can be made 25VDC and 100VDC. The leads can be bended for mounting purpose.
Above are our three kinds of Ceramic capacitors now. If you cannot find suitable products, please feel free to mail us.
