Can anyone identify these?
I would guess heat resistance but can't find a replacement.

1000uf 25v Film cap i think.
EDIT: Derp, those don't exist. Ill leave now.Last edited by goontron; 12-12-2016, 09:29 PM.Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

Excuse me while i do something dangerous
You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.
Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

they go here beside these sandblocks.
I bought nichicons but now I'm thinking twice....maybe some heat resistant sleeves or something would work.Attached FilesComment

Re: Can anyone identify these?
i think they are encapsulated electrolytics.
in the early days there where a number of attempts to stop them leaking ranging from putting epoxy over the bung or dipping the whole cap in epoxy to putting them in plastic boxes.
the russians (USSR) also tried the expensive method of using a solid plastic bung with a seperate rubber gasket.
that actually worked btw, i have never seen one of those leaked - but it's expensive to make.
what does a cap meter say?
if your sure it's fucked then cut it open and see what's inside.Comment

Re: Can anyone identify these?
tester says 1184uf 3.8ohms
new nichicon is 938uf 0.17ohms
schematics shows electrolytic.
the new caps are smaller so maybe I can push them away and put an asbestos sock thing over them.Attached FilesComment

Re: Can anyone identify these?
airflow would help more - maybe you can stick a small (40-60mm) fan inside just to move the air around and avoid hotspots.Comment

Re: Can anyone identify these?
Newer electrolytics are so much smaller, I'd move them away from the power resistors even 1/2" away helps alot. I use a dab of silicone sealant to tack them down.
The old caps are from a day of sealing them 100% for long life. Until. they. go .pop.Comment

Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages
The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.

Hy guys , i have a DVR board DS-80104 REV 2.2 that was powered wrong, i have some smds on the board that are blown and i can't identify them , maybe if someone has this board somehow and we can identify the smds', i have searched online and i can't find a schematic.
The smds are SOT-23-6 , one of them i think it has the marking ADJF since i found another one on the board with this marking , but the other one it seems that it starts with AG or it looks like. I would really apreciate if someone could help me identify those IC's .

Hi gang, its a long shot, but working on Lenovo Legion Pro 7 motherboard NM-F091, and trying to identify this component near GPU with marking "eHFQH" that is burned and shorting the board. Looks like power management IC
I couldnt find any schematic or boardview. The CPU side also has same chip. Any way to identify this chip? or take measurements from the good chip to determine what it is?
Any help would be appreciated... -
I mistakely pluged 100v japanese retro game console to 220v outlet.
So It seems that glass fuse and varistor have been blew up.
I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
Is there any way to identify varistor type in my sega saturn PSU?
Any reply would be appreciated.
EDIT:
It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage... -
detecting heat with IR LED receiver
I have some dark IR led, and want to know if it is be situable to detect pure heat (not visable glow ir radiation) in well lighted desk?
So, if I put hand over it in near distance like few centimeters, that detect rising heat, not covering it from light.
Something like termal camera, but in one spot, any simple circuit?...
