In all my years it's always been 2.2K. 2k2 is nice.

Meindert,

That is a new notation for me. Is it a European thing? I like it.
Compact!


Hi Doug,

Might indeed be a European thing. I checked some 'US based' schematics and
indeed, it is never used there. Funny how such common things are 'unusual'
to others :-)

That's the resistance that's printed on the top of all the surface
mount tiny resistors. You can't see a PERIOD that small....(c;

3600 planes with transponders are burning 8-10 million
gallons of kerosene per hour over the USA. R-12 car air
conditioners are responsible for the ozone hole, right?

This notation already existed long before SMD parts came to this planet.
There has been a similar discussion about this in another newsgroup a few
months ago. But the reason for this notation is indeed readability. A period
is just to tiny and they can disappear or appear when a schematic is copied.

The surface mount resistors I've used are marked with a three (or
four) digit code mimicking the standard colour code - a 2K2 (or 2.2K)
resistor would be marked "222", and a 10K, 103.

I think the 2K2 style notation was originally a European thing, but is
becoming better known and used in North America.
