identification

The first image shows a component that was smoking until it burned and changed its shape as shown. The second image shows another component that looks exactly the same. It exists on a different part on the same PCB. They have no part number printed on them. They are shorted, I mean they make a...

Hello, I would like to kindly request the assistance of knowledgeable specialists in identifying a few components that I need to replace in order to repair the motherboard of a Hach DR6000 spectrophotometer. I am particularly interested in identifying the component labeled “455F.” The...

Hello again everyone, So I've got a dyson supersonic HD07 in for repair. Normally it's just a small.number of generic faults which cause these to stop running but this one has me stumped trying to identify the correct part needed so thought I'd ask the experts. When I first stripped this...

Heya! I want to design a chess board which can ID the various pieces. I’ve read plenty posts here before, and I want to clarify I would like there to be no visible electronics and for the identification to not rely on pre-programmed positions. I’ll be using Arduino 4, but i’ve got a Raspberry...

Hi everyone. Im looking to repair a curcuit i have. It will no longer work if the device gets cold. If it is heated up, it will start to work again. Very strange. I want to replace an IC on the PCB of the device. I need a replacement , but can not find out what would be an equivalent for the...

I have searched for this part for about 8 hours in the past 3 days but have not been able to locate what part it is on Google, and Yahoo (via Firefox). I have deleted numbers from the back, then from the front into these two search engines, and also tried Google Lens. I have also conducted some...

So I have been working on a BASH amplifier out of a Triad Silver Omnisub and have come across a resistor that I’m having a hell of a time identifying the value of. It reads at very close to 39 ohms, but from the colors of the bands on the resistor, I’m stumped as to what it’s original value...

I want to create a chess board that detects where each piece is located. Existing technology from DGT uses small coils and capacitors, but this solution apparently does not work when metal is involved. My chess pieces have a small magnet at the bottom as they are going to be used on a...

These look like they would accept bullet connectors of some kind, but I can't seem to find the parts to actually look up what they interface with.

I am making a chess board with integrated AI for a year 12 school project and I am not sure what kind of components I will need to use to be able to sense what pieces are where at the start of each turn. I was thinking of using RFID but the range is too long I also thought about using smart card...

Hello, I need help identifying this transformer from a LED driver. 45C389J41 P.S. Why can I almost never find anything online from the markings on these small yellow transformers.

Hey team. New to the forum. Just need help identifying the following inductor on an HP laptop. Any info on what I can replace this part with would be greatly appreciated. -Swift

I'm trying to find the components of the PCB I have. But I have a problem with a 5 pin (I guess SOT23-5) component. Can someone help me abuot this? There are version1, version2 and version3 of the PCB and marking codes are AA43, AA44 and AACB respectively. There are reset button and error...

I'm looking for assistance identifying this old museum piece. So far I believe this may be a homemade variable transformer used for testing vacuum tube equipment. Any further insights would be greatly appreciated.

TLDR: ID & ideals on mangled through-hole components, images below: Story: The Torontonian's Tale of the Fridge Fiasco Out with the old, in with the new! Or, so the non-electronics hobbyist will say when an appliance malfunctions. But, me? No, siree bob! Not with a soldering iron and all the...

Hello all. I need help to identity a diode. Please see attached picture. . Thank you in advance.
