PLCC - Plastic Leaded Chip Carrier       

                                  

The Plastic Leaded Chip Carrier, or PLCC is a four-sided plastic package that has "J" leads around its periphery. These "J" leads occupy less board space than the gull-wing leads that other packages like the SOIC have. PLCC lead counts range from 18 to 84. PLCC packages can either be square or rectangular in shape. The ceramic equivalent of the PLCC is the JLCC.

   

PLCC body widths range from .35"to 1.15". PLCCs have JEDEC-standard package outlines. The standard lead pitch of the PLCC is 1.27 mm. The PLCC must not be confused with the LCC, which is a leadless and more expensive ceramic package.
