TDK Product Features

Chip varistors / Ceramic transient voltage suppressors (CTVS®) are ideal, surface mountable components for transient overvoltage protection. Available as single components in case sizes EIA 01005 to EIA 2220, arrays and ESD/EMI filters, these components are designed for circuit protection in automotive, industrial and consumer electronics. The field of application ranges from reliable, fast and low clamping ESD protection of sensitive electronics and data lines up to high energy absorption for protection against severe electrical transients. ESD/EMI filters combine ESD protection and EMI filtering e.g. in audio lines of mobile phones or in high-speed automotive bus systems.
