Help identifying this component |
|
|
I am trying to repair a combination electronic transformer/dimmer. It
converts mains in to 12V at about 80W to supply a floor lamp with
halogen lamps, it has an integral dimmer. The two suspect components
could be transistors, they are TO220 packages and have printed on them
the letters ST inside a sort or angled square with the numbers 9622.
Under this is the word Malaysia and under this is RELCO5. Anyone know
where I can find info on these or if you recognise them what
equivalent I could use. Thanks.

From the manufacturer of the lamp/supply.
That is apparently a house number for that manufacturer. 9622 is the
date code (middle of 1996) |

One German source:
http://www.wer-weiss-was.de/theme59/article140098.html
claims it's a house-numbered BUL59.
http://www.st.com/stonline/books/pdf/docs/5662.pdf
Looks plausible, but I have no way of guessing how accurate that might
be.

Hi Spehro,
The last poster on there mentioned an obsolescence list that seems to
suggest the BUL59 as the closest replacement.
Do you speak German? That is great, there aren't many folks out here who
do.

Nope. Survival German only (at least the Germans *try* to understand
my fractured words, unlike the French who are quick to give up). My
wife is fairly fluent in both- she studied them through university and
has worked in Germany and Quebec fairly extensively. I just stuck it
in googlefish. ;-)

Half the time I tried web translators like that I received back
something unintelligible. In France, if you want to learn it, the best
places I found were more rural areas. In Normandie and Bretagne they
tried really hard to decipher what we were trying to mumble. The said
they really liked it if someone made the effort at all.
But these Western languages are all pretty easy. When I read that your
son is learning Chinese, now that ought to be really tough for a non-Asian.

Why bother when a replacement is so cheap ? Unless you want to learn of
course.

ST = SGS Thomsom semiconductors.
9622 = wk 22 of 1996

Don't bother repairing - you don't know the failure mode. Buy a
replacement.
FYI I have something similar on my desk I ripped apart to have a look at
low voltage lighting techniques. Nice Litz wire on the output winding !

I learnt French from the age of 8 to 16. The earlier you start learning a
language the better. I got a damn good exam result at the end too !
Having said that I, hadn't *spoken* it much until I met some 'Frenchies' who
were visiting the UK ( students ) whom I got to know quite well.
It was only years later that - when with a Swiss g/f - her friends said I spoke
with a Provencale accent - entirely picked up from the Frenchies I'd met years
back.
Her German friends also took me for Swiss - No surprise there - lol. Schweiss
Deutch is a little less guttural than the real thing. I'd picked that up from
my g/f.
So - I picked up 2 regional accents without ever even going there !
Oh - and - yes - the French really like it if you speak their language to them
- even if you're a bit iffy. I reckon they appreciate the effort instead of an
arrogant assumption they'll understand English. It makes the world of
difference. French is a nice language to speak anyway !

Hello Graham,

Eight is about the cut-off from where on you'll always keep an accent no
matter what. Kids who move to another country before that typically
converse without an accent.

That happens a lot. I didn't grow up speaking English but honed it later
in business. So, there is a bit of Scotland in there, then Canada etc.
My teachers were from Kentucky and Louisiana which has put a little
spice into it as well. Oh, and one year we had an Australian. With Dutch
it is similar, it's very rocky by now but still sounds somewhat Belgian
because I lived a mile from that border and was a member of a Belgian
sports club.

I remember a US soldier who spoke perfect German. Actually it was pure
Bavarian.

The good news is that nothing is compulsory.

Sorry but I don't know who. Arnold? He's Austrian. Big difference.
Anyway, it was at least 25 years ago.

When I worked in Berlin, we would have conference calls in German with
our Swiss factory, near Basel. They sounded like they were speaking
German with a Swedish accent to me, kind of sing-song.
We had a Swiss guy in the facility in Hesse that spoke so fast in both
German and English that he often times got mixed up while translating
where he would start speaking German to the Amis and English to the locals.
The IT manager was from near Freiburg. He had a really nasal Freutsch
accent when he spoke English (more French than Deutsch and barely
understandable). |
