Capacitor Replacement Tutorial

Capacitance, voltage ratings and polarity are explained. You can replace faulty caps on your circuit board and bring your electronics back to life!

5 years ago I used this video as inspiration to replace the caps on the power board inside my TV. It still works to this day. 10 bucks in replacement caps.

You were so ahead of your time in the YouTube educational sphere. Kudos

This video is a life saver man, thank you for giving a capacitor replacement tutorial that isnt an hour and a half of rambling, short and to the point, I learned more in this two and a half minutes than most videos. Broke out the soldering iron and fixed a Sega Genesis.

12 years later. I for the first time I'm my life successfully worked on a PCB and swaped a 8.4uF 400v cap with a scavenged 10uF 400 v cap on my led room 30W light. Thanks for the heads-up about the polarity or I would have surely messed it up. 12 yeas and still helping people to this day. To the point shot and crisp information. Thanks a lot.

I kept looking for a video that would explain the voltage rating. Yours was the only one I found that explained the voltage rating of a capacitor. The video is more than 14 years old but still so informative. Old is gold. 🙂

A thing I would add to the end of the video: When you face a high voltage capacitor, you will get shocked if you touch positive and negative pins. In order to avoid electric shock, just take a screwdriver and make short circuit between positive and negative pins before removing the capacitor. Just with insulated gloves, lift up the board and make short circuit ( put screwdriver between pins in order to short circuit the capacitor, so it will be discharged and you will not get eletric shock ). You will be able to handle it with no fear. btw nice tutorial! Once I learnt about capacitors, I had in mind this and you prove it to me that it works like a charm!

That was a perfect tutorial. Short and to the point and informative. Why can't every tutorial be like this.

I can't really imagine watching a video that's uploaded 14 years ago and that impressively helpful

[MAGAMAN]

Looks like I finally found the right keywords to search! This video was awesome and It's not some boring Indian guy that can barely speak English with wires plugged directly into the outlets behind him like 90% of my other searches.

No one has ever explained this so freaking Subbed.

I just replaced a blown 400uf 300v capacitor without having any idea about it aside from the given data here. After watching videos about capacitor, I'm just glad I didn't had an accident while I was poking the damaged one with a screwdriver.

I replaced 5 bad capacitors on my Xbox today. I bought it new way back in the early 2000's, and when it stopped powering on a couple years ago, l noticed some bulging caps. I swapped in some new ones today and it powers on.

@ravengious V=IR meaning that for a fixed resistance (such as your body) more volts means more amps, meaning more danger. And yeah it doesn't take much current to kill you. 50 volts is enough to cause pain. Discharging a 100V cap through your skin will leave a nice burn mark. Anyone who tells you otherwise is a twit who is confusing static electricity charges (high voltage but low stored energy) with low impedance voltage sources. This includes many high school physics teachers.

Your tutorials are EXCELLENT! I wish I had a teacher like when I was a youth!

Just started to research on how to replace capacitors and this is the first video I clicked on. Great video and explanation in layman's terms. Thanks for the post.

[NickTann]

Glad I found this before I tried replacing my capacitors. Thanks man.

[chrishampartsoumian]

Love the style all of this video, brilliant. Also reminded of why it's fine to replace a blown cap with one with a higher voltage rating. Thanks very much.

once i was working with a power supply and i was fairly new to electronics, there was a 240v capacitor that was charged and i placed my hand under the circuit board where all the solder joints were, and after that i was shaking fir a good ten muinits

@grabedigger Seach digikey.com for anything!

Very well done. One note of importance-it should be made known in your final warning that the capacitor might have that 200 volt charge even if the equipment has been shut off or unplugged. Harry
