WIMA introduces its new metallized Polypropylene film capacitor range in compact design type WIMA MKP 4C, which compared to the traditional WIMA capacitors exhibits considerably smaller case sizes. As an example a 1.0 F/630 VDC capacitor has a by 57% smaller volume, and a 0.1 F/630 VDC capacitor would even be smaller by 59% than a conventional MKP 4. This capacitor series is available with capacitances from 0.068 F up to 2.2 F and voltage ranges of 450 VDC, 520 VDC and 630 VDC in PCMs 10 to 22.5 mm. Due to the dielectric used they are suitable for operating temperatures up to 110C and stand out for their very high resistance to ripple and peak currents. more...

WIMA PowerBlock modules based on double-layer capacitors combine the advantage of convertional capacitors as fast suppliers of electricity and batteries as notable energy reservoirs. PowerBlock modules are used for motor start, in railway technology, in hybrid and heavy transportation, in automated guided vehicules (AGV), in uninterruptible power supplies (UPS) or wind power systems. The use of PowerBlocks as energy storage increases efficiency and life time of the applications, saves weight and cost for maintenance, and is environmentally friendly. more...
