SMD or chip varistors are voltage-dependent resistors based on ceramic multilayer technology. They are widely used to protect electronic circuits in consumer devices and telecom, industrial and automotive applications against transient overvoltages, such as electrostatic discharges (ESD) and surge transients.

》How to Use ESD/surge Protection Devices: SMD Varistors

Chip varistors have both surge absorption capabilities and noise suppressing effects.
See the adaptive application fields of various components for ESD countermeasures as well as the optimal application fields of TDK's chip varistors / ceramic transient voltage suppressors, CeraDiodes, and multilayer chip protectors.
