TDK Multilayer Varistors (MLVs)

TDK Multilayer Varistors (MLVs) are SMD disk varistors from EPCOS that feature 12V and 24V supply systems and high-energy absorption capability in an SMD plastic package. These varistors offer no temperature derating up to 85°C, RoHS compatibility, suitability for lead-free soldering, UL approval, and PSpice simulation modeling for different pulses. TDK Multilayer Varistors are ideally suited for engine management, airbag, control units, electrohydraulic brake, ABS/ESP, sunroof load-dump protection, and jump-start protection in automotive applications.
