20. MOV for 230VAC Mains Surge Protection

Linda is designing the input stage of a 230VAC single-phase industrial power supply. 

To protect the circuit from mains voltage surges and transients, she needs to place a Metal Oxide Varistor (MOV) across the line and neutral after the input fuse. 

The MOV must safely handle 230VAC continuous without degrading, and should clamp surge voltages to protect downstream components. 

She wants a through-hole disc type MOV for easy PCB assembly. 

The company's approved vendor list (AVL) specifies Littelfuse for circuit protection components, so the part must be selected from Littelfuse on DigiKey. 

Help her select a suitable MOV from Littelfuse on DigiKey.
