The capacitance of the new multilayer Chip Varistor is 0.5pf typically. It is made of ZnO nonlinear conducting ceramics and designed by adding inner electrode structure, which has a good capability of ESD protection for circuits. It is especially suitable for ultra high speed lines, such as HDMI interface.
ESD protection capability is needed in most high speed line, which requires that the ESD protection devices have very low capacitance to avoid affecting the transmitting. On this ground, we are focusing on researching the varistor which has excellent ESD protection capability and ultra low capacitance (0.5pF).
