Distinguish Between Varistor and Y Capacitor

Mar. 31, 2022

Varistors and safety Y capacitors are electronic components and are widely used in daily life. However, some varistors have a similar appearance with safety Y capacitors. Many people can't tell which is which. Read this article to learn how to distinguish a varistor and a safety Y capacitors.

It is actually very simple to distinguish between a varistor and a safety Y capacitor. Through the parameters on the body, we can know which is a varistor and which is a safety Y capacitor.

Distinguish Between Varistor and Y Capacitor

Varistor screen printing parameters:
