Distinguish Between Varistor and Y Capacitor

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.

Varistor screen printing parameters:

1. JEC: The varistor brand is JEC

2. 07: The diameter of the varistor is 7MM

3. D: The shape is the di type

4. 471: The rated voltage is 470V

5. K: Voltage deviation is ±10%

6. Passed certification icons: UL, CQC, TUV and other certifications

20/06: Production time is June 2020

Safety Y capacitor screen printing parameters:

1. JEC: The safety Y capacitor brand is JEC

2. JD: double insulation

3. 472: The capacitance is 0.0047uF=4700pF

4. M: capacitance tolerance ±20%

5. Y1: The model is plug-in safety Y1 ceramic capacitor

6. Safety certification of capacitors: CQC, ENEC, VDE, UL, KC

7. Manufacture standards for capacitors
