Dear all
I want to know what these numbers represent in terms of watt in eagle package.

I could have figured a few of them
0207 means 0.25W
0411 means 0.5W

Does anyone knows what these numbers represent?
0613
0617
0817
0922

Take a look at this page:

http://www.interfacebus.com/resi...

Note in particular the second table which has the package designations and the dimensions in inches. I think I can detect a pattern there ;-)

Those are DIP resistors in Eagle RCL library.

So?

My point was that "0603" is almost certainly 0.06" by 0.03" in size.

So what is the power rating for those sizes?like 0613 or 0617 etc...

See table 1 on the page I linked.

Rather coincidentally an 0603 appears to be 0.063W - but I'm pretty sure that is NOT where the 0603 designation comes from.

The table just mentioned the SMD versions.
I'm pretty sure that 0613 and above packages has more than 0.5w in the range of 1w to 5w
Don't we have some standards saying dip packages dimensions in terms of watt?

SMD resistors can have various power ratings depending on their method of construction. You need to refer to the manufacturer's data sheet for a particular part's actual rating.

My original question is that I have found these THD footprints for resistors, I need to know what an average Joe(resistor) in technology usually can handle what power based on the resistors package numbers in eagle? For example the 0207 is basically an axial 0.4 and it can waste 0.25w!
All the above numbers are for THD resistors not SMD ones.
See them in eagle, in RCL library. Just type *207* in eagle search box!

Ali .. that is not how artwork design works.

Design is an iterative procedure based on selection of components needed to do the JOB.

One dos not select components ( do design work ) based on library footprints to hand in some CAD package.

YOU find the component with the desired value, power rating, and so forth. THEN, you go to EAGLE and find a package that fits what you have chosen.

If there is no EAGLE part that fit your chosen device, YOU make new EAGLE part OR you choose a different device.

Guys I'm updating my altium library, And because of that I want to mention their power in mylib so everyone can use them easily! And do not use the digits!

then go and search 5 to 10 manufacturers of those components and see if they all give the same rating.
or exclude the libs you do not have complete and fill them when you are in need of a component and checked the datasheet of the manufacturer of choise.

I ditched over 2000 components of our database a couple of years ago. now sometimes a component is requested and I start with looking in de old libs for good footprints and then make the link complete....
saved me looking up over 2000 components.

There is no point in mentioning power...That is down to the design engineer, not the PCB layout guy...
