Matters Needing Attention About Safety Capacitors

Jun. 29, 2021

In recent years, the application field of electronics has continued to expand. Safety capacitors are capacitors that do not cause harm to the human body even when fail, so they are widely used in power supplies. When using safety capacitors, what should you pay attention to? Let's read on to learn more.

Safety capacitors are divided intotwo types: X capacitors and Y capacitors. X capacitors are capacitors connected between the two power lines (LN). Y capacitors are connected between the two power lines and the ground(LE, NE) andusually appear in pairs.

Matters needing attention when selectingsafety capacitors:

1) When using capacitors in the cross-linepower supply circuit to eliminate noises, not only the normal voltageshould be considered, but also the generation of abnormal pulse voltages (such as lightning), which may cause the capacitor to smoke or catch fire. Therefore, the guarantee standards for cross-line capacitors are strictly regulated in different places, so certified safety capacitors must be used.

2) It would be better if the resistancevoltageof the capacitor is close to actual voltage in the circuit. This is a key point that is easytobe neglectedduring the selection.

3) It is advisable to purchase branded safety capacitors with a guarantee.

Knowingsome precautions in advance can reduce unnecessary troubles. It is very important to do some homework before purchases. And it is also important to purchasequality-guaranteed safety capacitorsfromformal manufacturers.
