Weird (to me) potentiometer code

[ekorz]

Hi All! I’m used to seeing potentiometer codes on stuff where the first two digits are a value, and the last digit it’s a factor of 10. So “202” is 20 x 10^2 or 2k ohms.

Well I’m looking at 239.

It’s not 23000000000 ohms... it meters at 2k (so 23 = 2 x 10^3 = 2000) so I’m wondering if the 9 is supposed to be telling me something useful. Any ideas?

Isn't it the manufacturer brand upside down?
GEZ?

 

[ekorz]

No the brand is on the blue part, HDK https://www.hdk.co.jp/english/prduct_e/prd0007_e.htm

Is it a linear pot?
Maybe the "g" or "9" indicates the type of curve or tolerance or something else...

 

[ekorz]

Yeah, seems linear. It’s the 5v on a psu, so maybe another way to ask is... is there something I should consider for a replacement? One material vs another or something? Probably just gonna buy a 2k linear and swap it in for science.

Probably just gonna buy a 2k linear and swap it in for science.

That's what I would do.

In my experience, voltage adjustment pots in PSUs are usually 1k or 2k. I haven’t seen anything else yet.

Is the 9 a wattage rating perhaps? 0.9w or 9w?

Well my new 2k pot reads 23Y. No smoke so far. I’m calling it a win.
