What is a 400V DC capacitor?

According to comments and answers, this capacitor is polyester (or polypropylene), with rating 400V DC. A capacitor is a capacitor, it doesn't care particularly about what kinds of signals go through it, as long as you stay within its SOA. PlasmaHH, there is some reason why some caps are rated 400VDC and some 400VAC, or 250VDC/250VAC. Isn't it?

What is a capacitor marking?

A capacitor marking is a code, which indicates the value of the component. It usually consists of three numbers, which indicates the value, and a letter, which indicates the tolerance. Tables usually provide a means to decode the numbers; however, there are also calculators available as well.

How do you know if a capacitor is 2a474j?

If a capacitor is f.ex. marked 2A474J, the capacitance is decoded as described above, the two first signs is the voltage rating and can be decoded from table 2 here below. 2A is 100VDC rating according to the EIA standard. Some capacitors are only marked 0.1 or 0.01, mostly in these cases the values are given in uF.

Is 400 volt a good polarity capacitor?

It has no defined polarity like the electrolytic capacitors have. In this application only an unpolarized and high voltage capacitor is ok because it must stand the mains AC voltage. 400 V is quite a low safety margin selection for 230VAC except if it's stated in capacitor's datasheet that 400 V means "continuously stands 400VAC".

Can a 400V capacitor be used with 230-250v AC?

In various circuits intended for use with 230-250 V AC I've seen capacitors labelled as "400V" (Examples: 1, 2) When I look at Capacitor specifications, they often give separate AC and DC ratings. For example: (I believe an X-rated cap is designed for use across AC supply live-neutral)

Is a 400 volt DC capacitor good for 230 volts?

@Chupacabras if your supply is 230 V AC then the peak voltage can be as high as 325 volts. Add (maybe) 20% for powergen issues and you get to 390 volts peak. A 400 V DC capacitor is OK but 450 V would be better and maybe, that is possibly why the 400 V DC capacitor failed. Feb 1, 2017 at 12:39 Your capacitor has plastic insulation layer.

According to comments and answers, this capacitor is polyester (or polypropylene), with rating 400V DC. A capacitor is a capacitor, it doesn''t care particularly about what kinds of signals go through it, as long as you stay within its SOA. PlasmaHH, there is some reason why some caps are rated 400VDC and some 400VAC, or 250VDC/250VAC. Isn''t it?

I have a capacitor marked 400v 68mf, I have looked online for

So the capacitor you found online should be a perfectly good replacement. To be more certain, you could also check the capacitance with a meter to be sure of what your markings mean 100%. 68mf = 68,000uf. Those 2 capacitors are NOT interchangeable.

Capacitor Code: What It Is and Why It Matters

By understanding these codes, you can accurately identify the specifications of a capacitor and select the right component for your electronic projects. In this blog post, we''ll delve deeper into the world of capacitor codes, exploring different coding systems, decoding techniques, and common misconceptions.

Replacing Capacitors With Different Values Guide

Yes, you can use a 450v capacitor instead of 400v as long as the other characteristics (such as capacitance and temperature rating) are identical. Increasing the voltage rating may help protect your circuit from higher voltages, but it also means that it can be more expensive. Can I replace a 370v capacitor with a 440v? Yes, you can replace a 370v capacitor …
