In flash applications – such as professional flash devices in photo studios or radar speed traps – capacitors discharge very quickly. The main requirements for flash capacitors are high energy per volume values, compact dimensions and a maximum flash frequency. The aluminium foils developed by FTCAP and its suppliers especially for this purpose make it possible to produce aluminium electrolytic capacitors with a high capacity-voltage (CV) product. Their fully welded design makes them ideal for high peak currents, with no compromises. This also minimises contact resistance, which ensures long-term stability. The high switching capacity of these electronic components is especially advantageous in flash applications with very short discharge times. That makes them ideal for a broad range of applications: FTCAP capacitors prove themselves in numerous applications, from hair removers to aircraft wing lights, flashing lights in wind turbine towers, and even radar speed traps.
