Hello The symbols Z, Y, X define the lower limit of the temperature range From +10°C Y -30°C X -55°C A digits are the upper limit of the temperature range 2 +45°C 4 +65°C 5 +85°C 6 +105°C 7 +125°C 8 +150°C 9 +200°C AB

Markings of this type are used to determine the electrical strength of the insulation, e.g.: class X1 = 1625 V- / 2 sec. class Y2 = 2000 V~ / 2 sec. ...the rest you will find in catalogs

I was looking for an answer to a question about markings. I found this document: link As for me, it describes the markings of anti-interference capacitors quite exhaustively.

I took the liberty in this old topic to add the file from the link here before it disappears into the depths of the web.

Hello,
I wanted to ask what exactly these markings (x2 y2 x1) mean - is there a standard that regulates this.

I know that it probably applies to anti-interference capacitors, but is it only such capacitors?
Such capacitors can only be used in filter systems or in any applications where capacitors are used ??

I'm hoping for help...

Hello

The symbols Z, Y, X define the lower limit of the temperature range

From +10°C
Y -30°C
X -55°C

A digits are the upper limit of the temperature range

2 +45°C
4 +65°C
5 +85°C
6 +105°C
7 +125°C
8 +150°C
9 +200°C
