Help Needed identifying a 2 Digit Capacitor

Hello everyone,
Very simple question.
Im struggling to identify this capacitor.
The backwards R + U is throwing me off.
Also not sure if this is .33 or 33.
Is anyone familiar with label on this capacitor?
Looking to replace it as you can see the one beside it has blown.
Thank You!

Welcome to AAC!

Sometimes searching the internet for the part number works:

If it's a capacitor, the value would be 100pF.

Components in that type of package could be capacitors, MOV, PTC fuses, among others.

@dl324 Thank you for the undwrwriters lab tip!

At least I do see some of the thought processes I've been having here as well.
The 33 at the bottom of the capacitor makes me think it's a 33 pF capacitor.
But the '101' in the v101u suggests that it is 100pF.
Ive been leaning towards thinking this is more of a model number and not part of the rating of the capacitor itself.

The post on ebay has a different marking where my unit has a '33' (or .33 Cant quite tell)
It has a 1N.
If im able to identify the exact rating of the capicitor i should be able to replace it with a similar capacitor of a different brand i'm pretty sure.

Thank You! I appreciate your time spent helping me out.

Ceramic caps usually use 3 digits to represent the value. The first 2 digits are the significant digits and the 3rd is the multiplier.

101 = 10 * 10^1 = 100pF
104 = 10 * 10^4 = 100000pF = 0.1uF
330 = 33 * 10^0 = 33pF

This capacitor is the First component after main power reaches this board.
And it does connect across the powerline @Ylli
It actually is supposed to recieve - 48 V DC.
(The Telcom industry in Canada Opperates on -48V)
The board is for an LED light with motion sensing capabilities. It is labbeled Ret1 Ret2 then -48 V DC on the powerline inputs.
My problem was that the casing on the outside of the light reads 120 VAC 60 Hz.
Im assuming that once upon a time before the original power cord was chopped and rigged up to be extended to run across our lab here there was a proper converter that was capable of plugging directly into 120VAC 60Hz and provide -48V to the light.
I was tasked with getting it to work again so I simply wired it up to a cord and plugged it into a wall socket and the capacitor blew with a nice spark!.

@SamR Thank you. I was able to locate that page but I cant seem to find a through hole Capacitor to match. Which is why I was hoping to fully identify it so I can replace it with a Capacitor that has the same functionality although potentially not the exact same brand.
