Protection against ESD and high-energy transients
for general use
TDK Corporation offers an innovative product portfolio of EPCOS CTVS®(=Ceramic
Transient Voltage Suppressors) for general use. The portfolio includes both multilayer
varistors (MLV) and CeraDiodes®. In this sample kit you will find the most frequently used
high runner types for general protection purposes. Based on a new coating technology
this product portfolio ensures a high level of protection both against ESD as well as against
high-energy transients.
