Identifying SMD resistors

[Buk]

There are 3 resistors in this image:

I think the values are:

1. 68k
2. 1k
3. 100k

Am I correct?

I'd agree 68K top and 100K bottom, but I can't read the centre one clearly enough..

I believe it reads "O1B".

The best I can do at enhancing it:

I think you are correct. The top one is labelled "683", so 68 * 10 ^3 Ohms.
The middle one is "01B" so the first value (100) with a multiplier of B, which is x10
Similarly the bottom one is "01D" but happens to be upside down in that view.

Thanks guys. I'd never encountered the EIA96 before and was trying to make sense of 010 and 018 or 810 using the usual scheme when I found it and things started to make more sense.

The October 2021 issue of Silicon Chip describes a set of SMD test tweezers which can measure the value of SMD resistors & capacitors. They sell a kit of parts for it.

Shame they don't identify the components; and the web address doesn't appear to exist?

I'm not sure what you mean by "they don't identify the components". So I've attached the other pages.

Nice find!

I've just bought that issue online from that site (about £6) - as well as the full magazine pdf, that gives access to the PCB designs and the PIC source code etc.

Nice find!

I'm wondering what that gives me that something like this or this don't?

 

[rjenkinsgb]

Probably not - but it's a nice design and, with the source code, allows for changes and improvements.

It's also good to see there are still some hobbyist electronics magazines with serious content!

I read the "01B" as an upside down "810". Hard to read if it is a "B" or an "8"

It's rather more obviously a B on some of the others like it -- there are 7 groups of 3 like that on the board -- *once* you realise that B is a legitimate value for it to be.

It's just really hard to photograph without a proper macro lens or microscope.
