WIMA MKP-X2 R series capacitors are suitable for demanding AC voltage circuits e.g. where voltage is supplied via a capacitor power supply (the capacitor is switched in series to the load circuit as a low-loss series impedance). Due to their internal serie connection the capacitors exhibit an about 1.5 to twice as high corona inception voltage and thus higher rated AC voltage values than comparable components without series connection. WIMA MKP-X2 R capacitors are now available with extended capacitance values up to 10 µF and a rated voltage of 400 VAC.

 Based on their internal construction and their non-polarized connection configuration WIMA DC-LINK HC capacitors can for example be connected as one 4500 µF / 400 VDC, as two 2250 µF / 400 VDC or alternatively as one 1125 µF / 800 VDC component. Depending on the case size and wiring version values between 85 µF / 1600 VDC and 4500 µF / 400 VDC are available. The capacitors are wound with a metallized Polypropylene film and boxed in a solvent-resistant, flame-retardant plastic case sealed with resin. Cases with screw fixing are optional. The new WIMA DC-LINK HC range is used in intermediate circuit applications of power electronics replacing electrolytic capacitors e.g. in DC intermediate circuits with increased voltage and/or switching frequencies of the inverter.

 Based on rectangular cells WIMA Double-Layer SuperCap modules are now available with values of 100 F / 5 VDC, 100 F / 14 VDC and 450 F / 16 VDC. The WIMA SuperCap MR modules make space-saving serial and parallel arrays possible. WIMA SuperCaps exhibit a significantly improved behaviour in terms of life time being achieved by a laser-welded, hermetically sealed construction of the cells in metal cases which makes penetration from outside impossible. They cannot dry up and can withstand a certain thermal expansion movement. Only by this innovation one can consider the component being suitable for long-year maintenance-free application.

 Double-Layer SuperCaps from WIMA are now also available as cascaded and balanced modules with capacitance values of 55 F, 110 F and 200 F and with rated voltages of 14 VDC and 28 VDC. The WIMA SuperCap modules replace, protect or support batteries in the context of new traction technologies e.g. in automotive, railway systems, wind power mills or in uninterruptible power supplies (UPS). The typical application is the quick supply of several 100 A to 1000 A in the direct current field. In comparison with other energy storage solutions WIMA SuperCaps stand out for maintenance-free operation, high life expectancy and comparatively low weight. When properly treated they have a service life beyond 10 years and can easily sustain more than 500,000 charge/discharge cycles. The efficiency is far higher than 90%.

 WIMA has extended its range of SMD film capacitors with PPS (Polyphenylene-sulfide) dielectric. Capacitance values up to 6.8 µF and voltage ranges up to 1000 VDC are now available. WIMA SMD-PPS capacitors have an operating temperature range up to +140°C and stands out for their stable capacitance and frequency behaviour versus temperature. All WIMA SMD capacitors are produced with the proven box technology showing a safe protection against mechanical and thermal stress during processing and application.
