The passive electronic components used to protect electronic circuits from overvoltage are called varistors. They are made of a ceramic material that is specially treated to have a non-linear resistance characteristic. Under normal operating conditions, varistors have a high electrical resistance. However, as soon as the applied voltage exceeds a certain threshold value, the varistor abruptly reduces its resistance. As a result, it dissipates the overvoltage current and protects sensitive electronic components from damage.
As the world's largest manufacturer of aluminium electrolytic capacitors, Chemi-Con has been driving development in this field since 1931. The core product portfolio is supplemented by other innovative components such as tantalum electrolytic capacitors, film capacitors, supercapacitors and many more, so that the manufacturer is characterised by a wide range of standard and special types of high quality, reliability and performance.
