MV Series – Low Voltage Leaded Dual Function Varistors/
RFI Suppressors
Multilayer Technology
Varistor Plus
Description
MV Series varistors/suppressors are dual function devices that protect electronic equipment
operating in the low voltage region against voltage surges and high-frequency noise, replacing two
components: a low voltage varistor and a capacitor.
The MV Series incorporates a varistor function in the DC voltage range from 3V to 125V and the
function of a high-frequency by-pass capacitor operating in the capacitance range from 10 nF to
1000 nF. They are intended for protection of all sensitive electronic devices experiencing both
voltage transients and high-frequency noise produced by electromechanical devices such as
buzzers, relays, etc.
MV varistors/suppressors are square shaped components with in-line leads, which require at least
30% less mounting space than the two components they replace.
Features
