Multilayer varistors: E series for automotive electronics
TDK Corporation has extended its product range of EPCOS multilayer varistors with the new E series, which is designed to assure protection from current surge pulses in automotive electronics. Thanks to their innovative glass passivation, the SMD protection components that are qualified to AEC-Q200 with an extended stress test are even more rugged and reliable than before. The range of their operating voltages extends from 14 V DC to 40 V DC. In addition to greatly reduced leakage currents, the new components are characterized particularly 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 B725*E* series are lead-free and RoHS-compatible. PSpice libraries for the E series are available under www.epcos.com/tools_mlv.
