Automotive Varistors

TDK Corporation has extended the product range of EPCOS multilayer varistors with the new E series that protects from current surge pulses in automotive electronics.

Because of innovative glass passivation, these SMD protection components are qualified to AEC-Q200 with an extended stress test and are even more rugged and reliable than before. Their operating voltage range extends from 14 V DC to 40 V DC. In addition to greatly reduced leakage currents, the new components are characterized by increased temperature stability up to 150° C. The electrical characteristics of these components remain stable even after exposure to repeated pulses.

After the series run-up of the small EIA 0603 and 0805 case sizes at the beginning of 2012, the portfolio has now been extended by large case sizes up to EIA 2220.

The components of the series are lead-free and RoHS-compatible. PSpice libraries for the E Series are available at www.epcos.com/tools_mlv .
