What’s a safety capacitor? What’s are the differences between X, Y and XY safety capacitors? Find out in this quick one minute tutorial.
About One Minute Tutorials:
I often include short tutorials in my videos. But they’re hard to find when you just want a quick answer to a question. So I’ve created this One Minute Tutorial series:
• Short snippets from my videos.
• A quick lesson without a lot of fuss.

Really objetive, I apreciate it ! ⭐⭐⭐⭐⭐

@Geoduck. Год назад

I've always called them "Death Cap". This is very useful information.

Short and very clear explanation. Trick to remember X and Y is very good :-) Thanks

What if my house installation only have 2 wire, live and neutral ? Is this the cause, why my pc sometimes give me shock when i touch the case? Because i manage to open my pc psu and find out theres 2 blue safety cap in main connector

Don’t capacitors pass ac? Please tell me why they don’t make a short across the line. Thanks!

Capacitors can also be used as filters whereas the capacitance value affects the frequencies that it will allow to pass. Think of capacitors in a crossover network, for example. The line capacitors use a capacitance value that creates a high-pass filter. So, the low 60Hz frequency of the line AC is blocked.

Do have one question. In older tube radios they use a wax capacitor I have one that is a .047 at 200 volts. Can a disc. cap. replace this type of cap.? if so what value would you use?

@FluxCondenser Месяц назад

In some cases it’s ok to replace an old wax/paper cap with a disc capacitor, but generally they’re replaced with a film type.

Are snubber caps (for both rectifiers and/or power switch) Y type?

@FluxCondenser Год назад

I believe they’re a different class of capacitor altogether. And while they can be self-healing, I don’t believe they use the X, Y, or XY designation found on safety caps. If anyone knows more, please join the discussion.
