ROHM Acquires Powervation

Ithaca, New York, United States

Kionix makes the worlds most advanced accelerometers and gyroscopes. Their products are currently being used or tested to provide anti-skid functionality in cars, improve suspension systems to smooth bumps, and stop rollovers. At the same time, the consumer electronics world is looking to use Kionix sensors to protect laptops from breaking when dropped and to allow video game controllers to respond to subtle hand motions instead of button pushes.

ROHM Co., Ltd.'s Tantalum and Polymer Capacitor Business Assets use manganese dioxide for the cathode layer. Compared with ceramic capacitors, tantalum capacitors do not have a decrease in capacitance due to DC bias and do not produce noise because they do not have piezoelectric characteristics. Tantalum capacitors use manganese dioxide for the cathode layer. Compared with ceramic capacitors, tantalum capacitors do not have a decrease in capacitance due to DC bias. Conductive polymer capacitors use a conductive polymer for the cathode layer. Compared to manganese dioxide type tantalum capacitors, conductive polymer capacitors achieve a significantly lower ESR (equivalent series resistance). It is effective for flowing high ripple current and removing noise at high frequencies. In the event of a failure, the conductive polymer is insulated, providing a safe structure.
