Post by thread:[OT] Samsung Parts

I have never especially noticed Samsung as a brand of electronic parts. (KAxxx for analog discretes). I note however that RS prices for Samsung discretes are generally much cheaper than competitive parts from other manufacturers. This may just represent a special RS/Samsung arrangement but may bear investigating. Of particular interest to me was a TO92 regulator (KA76L05Z) with low dropout specs and max input voltage apparently similar to the LM2936 (which I use due to its very low quiescent current, very low dropout, higher than many max input voltage) and at a MUCH lower price from RS. I don't know (yet) a local supplier for this brand but my particular interest at the moment is availability in Asia so it should be ideal in that respect.

Not especially cheap, but worth looking at. ========== Dale Botkin wrote: ...... >I just stumbled upon the ICL7663, programmable (2 resistors), low dropout, ><10uA quiescent current, logic controlled shutdown, and a tempo output >that looks like it could be used for generating LCD contrast voltage. >Works like a charm.

These chips are pretty cheap from Mouser.

Sean, RS stands for "Radio Spares" and they are a huuuuge ish orgnisation who supplky electrical and mechanical parts. They have branches all over the world. Their claims to fame are - - Vast product line - Large part are in stock locally. - Rarer items can be obtained in 1 day often or about 6 days at most. - Very very very expensive - Will sell in small quantities as happily as in thousands. (some small items have minimum order quantities but this is usually OK) They are a superb source of instant parts for prototype and one off work but you pay through the nose. SOMETIMES their prices are as cheao as anywhere else but often as not they cost 3, 5, 10 or 20 times as much !!! Usually about 5 times going rate! They should be in a city near you and every EE should have an account with them (it's free, no complaint about small quantity, ewxcellent CD ROM data resource, excellent catalog (but our one has prices ij rear this year which is a pain). {Quote hidden}> >| >| Sean Breheny >| Amateur Radio Callsign: KA3YXM >| Electrical Engineering Student >\--------------=---------------- >Save lives, please look at http://www.all.org >Personal page: http://www.people.cornell.edu/pages/shb7 >.....shb7KILLspam@spam@cornell.edu ICQ #: 3329174 > Russell McMahon _____________________________ - http://www.easttimor.com Updated regularly: 100,000 refugees STILL in West Timor face starvation! - http://www.sudan.com And you think Kosovo and Chechnya are bad!

Thanks, Russell, and to Alan, for the URL. It is amazing to me that they have a pull-down list of about 100 different countries in which they have affiliates and the U.S. is NOT listed! I wonder if they just didn't want to try to compete with Digikey,Mouser,Pioneer, etc.? Another interesting thing to me is that I have seen people on this list mention "Radio Spares" before, but I always thought it was yet another derrogatory reference to Radio Shack!
