Can't find the name of SMD caps "case" for assembl

Post by batchas » Mon Feb 18, 2019 9:43 am

I’m blocked at some point cause I don’t see what is to be written for these caps under „case" for a BOM that has to be send to a manufacture for assembly.
In Diptrace it’s written „CPOL-USC“ for all the big caps, in despite of the fact that they don0t have the same size (different values), so I’m hesitating.

I can’t find it in the datasheets (I find the dimensions, but not the „case" reference - nor something lile "CPOL"). First time I use these, cause I always replace them with TH, but this time I’d like to have all on my PCB as SMD as it'll be assembled by machine.

Reference: EEE-FK1E100R
Description: Aluminum Electrolytic Capacitors - SMD Aluminum Electrolytic Capacitors - SMD 10uF 25V
Case: CPOL-USC
Dimensions / Pattern: CAPAE-4.3x4.3h5.4
Datasheet: https://www.mouser.fr/datasheet/2/315/A ... 947564.pdf

Reference: EEE-FT1V470AR
Description: Aluminum Electrolytic Capacitors - SMD Aluminum Electrolytic Capacitors - SMD 47uF 35volts 5x5.8mm SMD
Case: CPOL-USC
Dimensions / Pattern: CAPAE-6.6x6.6h5.7
Datasheet: https://www.mouser.fr/datasheet/2/315/A ... 130326.pdf

I dunno if I can simply write for instance: CPOL-USC-4.3 and CPOL-USC-6.6?

I think this has to be answered by the manufacturer. Only they know what values they're expecting to see in that field.

Hi batchas,

i think C Pol is standing for capacitator polaraized.

As you see here:

https://macrofab.com/blog/the-footprint ... apacitors/

or https://www.tutorialspoint.com/basic_el ... citors.htm

I found for panasonic smd Polarized

https://industrial.panasonic.com/cdbs/w ... 0C1181.pdf

In this pdf you can see the SizeCode in the Demension Section. And now you know what Size you need and what case for which Capacitator.

I maked in the attached file: (not nice but hopefully understandable)

It's in the datasheet you attached.

Oh! Indeed :doh:

Okay. Thanks :tu:
I worried too much then.
I saw these in the datasheets, but I was actually expecting something like what I have for the other components used on the PCB: TO-252-3, 0603, SOT-23-3 and so on. This kind of naming.
