jb Capacitors Company -- Super Capacitors from jb capacitors

Super capacitors are ideal when a quick charge is needed to fill a short-term power need.  They can be used in solar power applications, battery back-up applications, battery applications, flash-light applications, etc.

Super capacitors have also made critical inroads into electric powertrains. The virtue of ultra-rapid charging during regenerative braking and delivery of high current on acceleration makes the super capacitor ideal as a peak-load enhancer for hybrid vehicles as well as for fuel cell applications.

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.
