TDK Corporation has extended its product range of EPCOS multilayer
varistors with the 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 14V DC to 40V 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.
