 AGING

Following the final heat treatment, all type of ceramic capacitors lose their capacitance value approximately according to the logarithmic law due to their special crystalline structure. This change is called ' Ageing ' and is defined by an ageing constant, which gives the percentage loss fold increase in age.

SAFETY RECOGNIZED AC RATED CERAMIC CAPACITORS

 

CEDICOM ELECTRONICS has introduced a series of AC capacitors in their range of single layer ceramic capacitors. Important features of the AC capacitors are their reliability and their excellent temperature stability with the range.

An AC capacitor is essentially designed for application with power frequency alternating voltage. Ceramic capacitors make excellent suppression capacitors since they are non-inductive and thus have low impedance at high frequencies. Hence they are extensively used to reduce electro magnetic interference caused by electronic and electrical apparatus. They are also used to suppress surge voltage or arcing caused by appliance ON/OFF switches and to isolate accessible parts of equipment from AC mains voltage.
