Eagle component naming, package [sebuah catatan pencarian]

Ini adalah hasil pencarian saya di Internet mengenai penulisan ukuran komponen (package) pada aplikasi CadSoft Eagle.

 

With regards to the resistors, when you are looking through the ‘resistor’ library the parts have a ‘type’. The First half is the width in mm (at least for the EU parts) and the second part is the length. The ‘grid’ is the distance between the two solder holes. 

For example, a 0309/10 resistor is 3mm in diameter, with a 9mm length and the holes are set 10mm apart. Therefore, simply measure your resistor and use something similar.

“(1 W/0207 size to > 3 W/0617 size)” …

And what does type 207 mean? I know it a package but I don’t see 207 in the data sheet. What does types 204, 207, 309, 411 mean? …

<<>> It is the diameter and size of the resistor body in centimeters. So the 1. value in your example means 1 Watt and body size 2×7 Milimeters = 0,2×0,7 Centimeters. Forget the x and commas and you have 0207. (Like you write 2k7 for a resistor value of 2.7 kilo ohms). 
The 3 Watts resistor has a body of 6×17 milli- or 0,6×1,7 centimeters. Since it is not really healthy for a resistor to bend the wires sharp at the body you leave a milimeter or two before you bend them as seen at page 4 of your pdf-file. So this leads to the “/value”. If you check the eagle rcl.lbr pick a resistor 0207/7 and a 207/15 and place them in the schematic. They look alike but if you switch to brd you will notice the differece. The bodies are equal but the wires have a different length. So the value behind the / is the grid size of the part.

To find something suitable in the libraries

From the Kemet data sheet:

The C315 package has the following characteristics:

Lead spacing 2.54mm (0.1″)

Lead diameter 0.51mm (0.020″)

Package width 3.81mm (0.15″)

Package thickness Std Voltage 2.54mm (0.1″) , High Voltage 3.18mm (0.15″)

 

In the library rcl.lib select your capacitor symbol preference of either C-EU or C-US

From the listed capacitors the ones that fit you size requirements have the package C025-024X044

C025 = Capacitor with lead spacing of 2.5mm

024X044 = tPlace depiction of package size 2.5 x 4.4mm. This is a suitable match for the datasheet values of 2.54 x 3.18mm.

Opening the library, check the drill diameter of the pads. In my library its 0.032″ which would suit the lead diameter of 0.020″.

The general purpose fixed resistor devices are called either R-US (if you like the US zigzag line type of schematics symbol) or R-EU (if you prefer the European simple rectangle.] The package options are numerous, but make sense after you realize that there’s a common format: WWLL/SSwhere WW is the body width, LL is the body length, and SS is the hole spacing, all in truncated millimeters.

A typical 1/4W resistor measures about 2.5mm in diameter and 7mm long; hole spacing depends on how you bend the leads. So R-US0207/10 is a 1/4W resistor with 10mm (actually 4*2.54, or 10.16mm, since we want to stay close to a 0.1 inch (2.54mm) grid.) R-US0207/2V is the same resistor mounted vertically with 2.54mm lead spacing. 1/8W resistors are similarly designated R-US_0204/SS”

Capacitors are worse than resistors, largely because their bodies come in a wider variety of shapes (that are less standardized), and of course there are all those different types; disk, ceramic, mylar, film, electrolytic, tantalum, AC filter, etc (and those are just the FIXED value caps!) Again, threre are slightly different US and European schematic symbols C-US and C-EU in rcl.lib.

Again, there’s a plethora of packages, but there’s a standard format. In this case it’s SSS-WWWXLLL, where SSS is the lead spacing (with an extra digit this time!), WWW is the body width, and LLL is the body length.

Polarized caps are similar (CPOL-US or CPOL-EU in rcl.lbr), with a package name like TSSS-DD, where T is a type designator (E for electrolytics, TT for tantalum drops, for instance) SSS is the spacing again (only now it probably has an actual decimal point!), and DD is the diameter (for radial caps).

<<>> As I am based in Europe, I use the European (EU) symbols for resistors, capacitors and inductors. If you prefer the US symbols, select them instead.
For any of the libraries, expand the library and you will see a list of components. Use the following table to help find the part you require, note SMT = Surface MounT, PTH = Plated Through Hole.
