I need help with identifying this varistor. I hhave Been trying to figure it out since 5 pm yesterday. I cannot find anything about it. Any help is greatly appreciated.

  • \$\begingroup\$ I'm merely a hobbyist and no professional. But I would have guessed that the "103" would mean 10nF (which can apply to varistors); that although the 560-2 VDE spec can apply either to caps or to varistors, the 5U suggests Y5U (may be consistent with 10nF); and so I'm leaning towards "capacitor." Are you sure it's a varistor? For example, see this from Panasonic ceramic disc caps. \$\endgroup\$

  • \$\begingroup\$ I have no idea between the two. But either way, I need to find what company it is from. Not so worried about replacing at the moment or specs. Just need to know who manufactures them. \$\endgroup\$

  • \$\begingroup\$ Funny though that all the other Matsushita varistors I find are ZNR line, none of them are from this NS line. \$\endgroup\$

It seems to be a part from Matsushita, which would now be Panasonic.

manufacturer marking

I found a few parts with that logo and Matsushita mentioned, but can't find a real source for that.

@jonk mentioned that it is likely a capacitor and not a varistor.

There is a NS-A line of capacitors offered by Panasonic, which could be the successor for the NS you have there.

  • \$\begingroup\$ Anyone know where I can find a possible replacement then? \$\endgroup\$
