Protect electronics against high voltage spikes and surges
This MOV is suitable for 220V AC line protection in a typical electronic devices against voltage surges and spikes, such as those generated by inductive switching transients.
Many users ask us that MOV says marking as 470V so how is it suitable for 220V application.
Let me explain
The AC mains you get said 220V RMS. So peak voltage is 308V = 220V x 1.4 (VPeak = VRMS × √2)
This MOV 10D471K is having 300V AC RMS rating. So its suitable for 220V AC mains applications.
