Hi,
 
When I build a Polarized Molded Capacitor the naming of the Footprint is wrong. In 2015.08 it is CAPPM.
 
From the naming convention it should be CAPMP.

In the Molded Body calculator the auto-generated names are:

  • The Polarized Diode is DIOM
  • The Non-polarized Diode is DIONM
  • The Polarized Capacitor is CAPPM
  • The Non-polarized Capacitor is CAPM

Note that the prefix always ends in M for molded body.

Here is the link to download the standard (which had a typo) - http://www.pcblibraries.com/forum/ipc7351-sm-footprint-naming-convention_topic479.html" rel="nofollow - http://www.pcblibraries.com/forum/ipc7351-sm-footprint-naming-convention_topic479.html

Some days before it was the other typo (CAPMP). Also in your pdf. In the downloadable fpx file the CAPMP is also used. And the POD also have this CAPMP naming.

So is the question why changing a naming convention that works for years?

Because the "M" (for the package type Molded Body) really should be at the end of the Footprint Name Prefix.
 
Our goal is to correct flaws to improve the standard for the future.

In which case, you may wish to correct the remaining typo in the Naming Convention PDF:
CAPPC instead of CAPCP

The Library Expert already produces a CAPPC footprint name.
