EIA standards?

Where do I get a list of all possible values for Package/Case of Capacitor? For example: 0805, 1206... There must be a standard out there and I am not sure which one. I couldn't search on global.ihs.com

Can someone help?

From a manufacturer's spec sheets.

There is a standard series of values (same as for resistors) that is commonly used, but each manufacturer is free to decide what range of values and dielectric types he can put in a particular package.

I am sure each manufacturer can have their own value but there must be a rule about making up these Package/Case right? For example, 0805 must mean something, different from 7361-38. But why it also in the form of

4.3mm x 4.3mm x 4.0mm? Is there a document about "decoding" Package/Case? Or how do I get a full list of all possible values?

Thanks.

0805 refers to the inch size of 0.08" x 0.05".

I know 0805 but What about 7361-38 ? Is there a limited number of sizes? Like is there 0806 or 0905?

For surface mount resistors and capacitors, there are a series of standard packages whose sizes are given in units of 0.01 inch - an

0805 package is 0.080 by 0.050 inch, a 1206 is 0.12 by 0.06 inch, etc... There is a similar series of packages with dimensions given in metric units.

You still have to look at the manufacturer's data sheets to be sure what size the package is, and what values and dielectrics are available in that package size. (When I buy from a North American distributor, I assume that the package sizes will be in inches.)

More than often the data sheet does not tell you the meaning. Why sometime we have something like 1.5mm x 1.7mm but some other time we have 3.2mm x 2.5mm x 1.3mm?

I also see this format "7361-38" very common too. What does it mean?

I don't recognize that format - you'd (still/again) have to look at the appropriate datasheets to see what the package looks like. Manufacturers may assign their own arbitrary designators for their own (or even for "standard") packages.

Yep, I agree. I did a little research and found this site

formatting link

So look at this paragraph

# Tantalum capacitors:

  • Size A (EIA 3216-18): 3.2 mm =D7 1.6 mm =D7 1.6 mm * Size B (EIA 3528-21): 3.5 mm =D7 2.8 mm =D7 1.9 mm * Size C (EIA 6032-28): 6.0 mm =D7 3.2 mm =D7 2.2 mm * Size D (EIA 7343-31): 7.3 mm =D7 4.3 mm =D7 2.4 mm * Size E (EIA 7343-43): 7.3 mm =D7 4.3 mm =D7 4.1 mm

I wonder how do you know it is HxWxD or WxHxD or whatever?

Also for 3216-18, where does number 18 come from?
