MV Series Low Voltage Leaded Dual Function Varistors/RFI Suppressors
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
10nF to 1,000nF. They are intended for protection of all sensitive electronic
devices
experiencing both voltage transient 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.
