Munich, Germany, January 2015: Panasonic Automotive & Industrial Systems has improved and extended its portfolio of high capacitance Gold Cap Electric Double Layer Capacitors (EDLC). New versions are available which can operate at lower temperatures suiting industrial applications, while other devices have been increased in capacitance.

Stacked coin-type Gold Caps now feature an operating temperature range from -40 up to +85degC. Explains Melanie Raimann, Panasonic’s European Product Marketing Manager, Capacitors: “We have improved the performance of our products at low temperature and still can offer non hazardous and leakage proof EDLC.”

Also, Panasonic has uprated the capacitance of it RF and RG series devices to 1F and 1.5F respectively, enabling longer backup times. Both RF and RG series devices feature a lifetime of 2000 hours at 85degC, a leading performance amongst suppliers of EDLC technology parts.

Instead of a dielectric, EDLCs use a physical mechanism that generates a double electric field which acts like a dielectric. This means that they exhibit very long life times and can be charged and discharged very quickly. Gold Caps exhibit no charge and discharge cycle limitation and have no ‘memory effect’. Overcharging is impossible so no charging control circuitry is required.

Gold Caps are maintenance-free, contain no toxic substances and are RoHS-compliant. Devices are highly suitable as a replacement for secondary batteries, in long life applications such as metering and backup systems, in solar battery operated circuits and quick charging circuitry.
