Vishay / BCcomponents MLV0805E3 SMD 0805 Multilayer Varistors (MLVs) are surface mount multilayer surge suppressors with inherent bidirectional clamping and excellent energy / volume ratio. Vishay / BCcomponents MLV0805E3 come in a size 0805 (2012M) package with NiSn terminations. These MLVs provide over-voltage and transient voltage protection in data lines and I/O port protection as well as protection against ESD transients.
