What happend to 320K resistors ?
<< < (20/27) > >>
Jan Audio:
Thanks all.

Why i use such a DAC ?, it works, i am just happy with stuff that works.
Jan Audio:
This DAC reacts instantly, while a SPI DAC is slower.
It uses a few parts, the other DAC has more resistors.
MK14:
Requirements apparently met:

* Through Hole
* 1% Tolerance
* In Stock - Almost 700,000
* Less than $0.05 each. These are around $0.035, for x1000, less for bigger quantities
* 320K
* 0.5 Watts
* Metal Film

I have no idea on the quality of that supplier, so check them out yourself, please.

Stockpiling obsolete parts is a serious thing in this hobby, and you can make good money also if you buy enough.

With parts that have no substitutes, sure. But ordinary resistors? No way. A high-volume manufacturer that needs an unusual value will just order them (or even custom values), since they need lots anyway. And for small volume projects and repairs, you just use combinations of common values.

DigiKey shows several pages of 320 k \$\Omega\$ TH resistors, but none of them is stocked.  If you have need of a sufficient minimum order quantity, they will supply you.  If it were me, I would use two resistors in series.

I know that. You simply rephrased my reply, which was in response to OP’s claim of there being lots of money to be made in stockpiling “obsolete” resistors. I was explaining why that’s silly, since volume customers can get them if they need them (and wouldn’t buy them from some random guy anyway), and small customers would just design around the problem by using combinations. There’s no significant clientele for old stockpiled resistors.

Seriously, how hard is this?

It seems very hard to make a 320K resistor like this.
