Capacitor + diode identification help (pics) - solved
« on: September 16, 2023, 04:32:19 pm »
Edit: I added a component to avoid creating a new topic. I feel like I'm spamming :)
It's a diode. No markings (see pic) it's the white one, bigger than others.

Looks like a germanium diode and from another source it has two (2) black stripes.
Ok, looks like a 1N34A.



Yet again, I have two caps with AE1 marking but I can't figure out what they are.

Values show as 26-28pF but no Vloss nor ESR readings. I can get a reading every 10 times and it varies.
No idea if it is correct because it's a kind of cap I don't know of.

As I have to order new ones I'd rather be safe asking.

Thanks.

P.s. I tried many online SMD id sites but I couldn't find anything. I'm talking 30+ minutes.

Edit2: AE1 could be the manufacturer's id code. On the board are others and have different markings. Probably impossible to track.

Could they be precision capacitors? Mica???

What is the application?

On an old motherboard.

Frack on a stick ( Dr Reid- Scrubs), it connects to the Xstal oscillator (32KHz). So ~26pF sounds good, the caps probably corroded to the pads that are in...
Reading you made me check and realize it was there all along. Guess doin' stuff while tired ain't the best course of action...
Any cap will then do, unless not :)

Edit: yes, probably a 27pF, being readings 26 and 28 I'll go with the average.
