Need help identifying a ceramic cap

[axlmastr]

Inside the AC/DC adapter for my trusted DLink 614+ WiFi Router I found a domed and dried cap (Teapo 330uF 25V). The router just died one day and I substituted an adapter from another 614+ and found the culprit. In attempting to crack open the heat-sealed case of the adapter I damaged a ceramic disc capacitor in proximity to the edge of the PCB. I have found another one on the board to reference its markings since some of them were damaged. This is the typical radial variety wafer-looking ceramic disc you see all of the time, light-brown to orange in color about 7mm edge to edge. It was in parallel with a resistor and diode on the particular trace that leads to a small transformer marked 04-0222. The reference piece has the markings T01M over DV. The reference piece is paralleled in the same mount holes as a Teapo 22uF 200V and I am sure of the markings. Can anyone tell me what the value of this capacitor is? The ceramic came from the input end of the PCB since the output end has the larger transformer and the domed Teapo cap I mentioned earlier. Damn I hate it that I hurt parts I didn't need to. If I can replace the ceramic then all I have to do is plug it in since the aluminum electrolytic replacement for the domed Teapo is in and ready to go. I miss my 614+. The adapter wasn't hard to fix once I got it open except for damaging the ceramic. Any help is appreciated.

If it is a Zener diode which I think it is you can replace it with anything basically, or just plainly remove it (and watch the d-link fly when you get a power surge)

Thanks for the reply Per, but I'm thinking it's a capacitor since the legend marking on the PCB is C2. If it were a diode it would be D or ZD. Anyone got any ideas how to determine what this cap is? Wafer ceramic marked "T01M DV".

Re: Need help identifying a ceramic cap

Are you sure it isn't "101M"? That would be 100pF, +/-20%. Sounds like it's a snubber cap (the resistor and diode being part of the snubber network); are you sure your visual sample is the same value as what was broken?

Thanks for the reply PeteS. Yes, I am sure of the markings "T01M" on the reference with magnification. Underneath that is "DV". There are only two of these exact components placed on the entire PCB. I've heard of snubber circuits before. You may be right in regards to the damaged component's usage in that respect. In the reference it is placed across an aluminum electrolytic in the same holes- 22uF 200V.
