Hi guys, i have a circuit board with a blown znr varistor,
the markings on it says 14k471u S45

so far i can only work out the 14 = diametre and 471 is the capping voltage.
I'm not sure with that U stands for or the S45

i couldn't find this at farnell or rsaustralia.

does any one know where i can get my hands one of these varistors.

The manufacturer logo is a square with the letter M inside.

thanks.
