They're just normal metallized film capacitors (0.22uF and 47 nF), not X or Y class caps. AFAIK, you should be able to replace them with other normal film caps.... -
The white ones are indeed ceramic capacitors. As you can see from the image here, ceramic capacitors can be white. Unfortunately, many smd components can be white, but we can get confirmation from the capacitance written on the packet. As for the purple one, I'm not sure. I thought it could be a smd inductor, but I couldn't find any evidence of purple SMD inductors.
As a side note, I'm guessing the father did some radio/RF work. 3pf ceramics aren't usually used for filtering, but are more common in radio/RF applications for tuning and adjusting frequencies. Personally, the only places I've...Leave a comment:

It is a Nichicon FPCAP capacitor, likely RHS or RHA series. Datasheet: e-rhs_rha.pdf From the FP at the top, I suspected it was an FPCAP. From there, I did a parametric search on Nichicon's website and looked at which capacitors were red in the picturesLast edited by andrewsawesomr; 04-28-2026, 08:25 PM.Leave a comment:

I would double-check the capacitance and ESR of each set of caps (each bag of capacitors). If the ESR and capacitance are good, I would use them....Leave a comment:

You don't have to worry about the tolerance field in this case.Leave a comment:

The voltage value on that cap doesn't matter as long as it's at least 3kv. I just recommended that you include multiple voltage values in the search so that you can see all the compatible replacement parts. The part I linked is the cheapest replacement part from Mouser.Leave a comment:

That's fine. The only thing I would recommend is that when you make your selection with voltage, select the 3kv, scroll down to the end of the voltage list, hold shift, and click on the last available voltage (10kv in this case). This gives you more options.

The first capacitor is 100 nF at 10V, the second capacitor is 10 pF at 3 kV. In the second one, the size is given (1808, 18*8) and you can assume it's a ceramic capacitor by the capacitance. From there, you can go to an electronic components distributor, go to the ceramic capacitors category, Select size 1808 (in), select voltage 3kv and up (select the 3kv, scroll to the end of the list, hold shift, and click the last available option), and capacitance 10 pF. For example, here is a correct replacement: https://www.mouser.cl/ProductDetail/...DQE4nP0A%3D%3D...Leave a comment:

The series look good. For the 16 volt ones, just make sure the application isn't capacitance-sensitive, otherwise you might be better off getting the 1500uF UHWs.Leave a comment:

Can you provide the brand and series of the planned replacements?Leave a comment:

Let's start with some easy things. Do the capacitors have a brand name on them (some common ones include Elna, Marcon, Nichicon, Panasonic [Capital M in a Box], Rubycon, and Sanyo). Does the capacitor have a temperature rating like 85°C or 105°C? These factors will help us figure out the specs of the capacitor.Leave a comment:

Can you upload some pictures of the capacitor?Leave a comment:

The Everest I2S drivers are available from Microsoft here. To update the driver, open Device Manager, right-click the Everest I2S Codec Audio Device, click Update Driver, click Browse My Computer for Drivers, and navigate to the folder the driver you downloaded is in.Leave a comment:

Since Thomson doesn't provide drivers, let's figure out what audio device the laptop has. Press Ctrl+R simultaneously, then type msinfo32 and press the enter key on your keyboard. Go to Components>Sound Device, then take a screenshot of that page and upload it in a reply.Leave a comment:

Funny enough, the only OST cap I've seen fail was an RLG series - their general purpose 105C caps. It was in a Bestec power supply though (in a Dell Vostro 200), so it probably wasn't set up for a long life....Leave a comment:

I wouldn't, I've seen many cases where the caps are rated for a lower voltage than what they print on the sleeve and will explode if exposed to voltage printed on the sleeve

Any reason not to order from DigiKey, Mouser, CPC Farnell, RS Components, or LCSC (for electrolytic cap brands on LCSC I choose Cornell Dubilier, Kemet, Kyocera AVX, NCC, Nichicon, Panasonic, Rubycon, Suncon [not Su'scon], Taiyo Yuden, TDK, Vishay Intertech. and Yageo) (for polymer, you can use just about anything on there with a...Leave a comment:

If you're looking for electrolytic cap kits, they have plenty at DigiKey from good brands.Leave a comment:

If you're replacing those caps, you should also replace the VRM caps as they are what makes sure that the CPU gets good voltage and has enough current to function properly (see circle in uploaded picture for location of caps recommended to replace, your board might be a little different, but you get the idea). I would order all of the capacitors in one go just in case and only solder in the ones needed, but that's your choice. Let me know the brand and model of the caps if you want recommendations, otherwise, you can always look through the Datasheet Depot and try to find replacements yourself....
