Murata announces that its Power MONO ceramic capacitor has been designed into a hybrid electric scooter. Power MONO ceramic capacitors are much more compact than their film or aluminium electrolytic counterparts and feature high allowable ripple current. Further, Murata designed innovative metal terminals for the Power MONO series that prevent cracking in the ceramic material when exposed to mechanical stress. Four Murata Power MONO capacitors are utilised in the scooter’s power conversion system, on a board designed for smoothing the inverter. The capacitors are used to reduce the surge generated by the IGBT. Until now, film or aluminium electrolytic capacitors were used in this application, however these types suffer from low heat resistance as they both contain organic material. Murata’s ceramic capacitors are made entirely from inorganic materials and have a very high intrinsic resistance to high temperatures. The capacitors used in the hybrid electric scooter application can be used in the standard automotive temperature range, up to 125oC. These Power MONO ceramic capacitors are by far the largest in Murata’s product range, measuring 32 x 40 x 4 mm each.
