Decoding Capacitor Marking?

[meeshu]

I'm trying to understand the marking on a small blue ceramic capacitor with three lines of marking.

First line has - BN
Second line has - 101K
Third line has - 1kVL

From web searches and general understanding of components -
> the BN means the capacitor dielectric and/or the temperature coefficient of capacitance change with temperature.
> The 101K means a capacitance value of 100pF with capacitance tolerance K (± 10%, I believe).
> the 1kVL means a rated voltage of 1000 volts (1kV), but the capital "L" at the end is a mystery!?

So what does the "L" at the end of the third line mean, please?

And, if possible, can any manufacturers who make this capacitor be identified also, please?

Thank you.

PS I can't seem to attach images of the capacitor!?

Thanks.

But that reference doesn't seem to explain the meaning of any letters after the voltage rating(?)

Most ceramic capacitors I've seen only have the voltage rating marked (such as 1kV) without any following letters. So I suspect the "L" marking after the voltage rating on this capacitor may be specific to only one or a few manufacturers?

Regardless, I would still like to know the meaning of the letter "L" marking.

The only thing that makes sense is a tolerance code.http://my.execpc.com/~endlr/markings.html

Thanks.

But there is a capacitance tolerance code (K) already marked. And as far as I'm aware there aren't voltage tolerance codes (for ceramic caps)?

If that "L" is actually the voltage tolerance code, that is very unusual!!

Anyway, it would be good to get verification of this by finding a ceramic capacitor manufacturer who actually states clearly the function/meaning of the letters after the voltage rating marking.
