PLCC Socket

Plastic Leaded Chip Carrier (PLCC) is a low profile, thin four-wall socket built in a plastic housing used to encase integrated circuit chips.

Available in surface mount (SMT) and through-hole (THT) versions, the PLCC is designed with the standard “J”-leads. The lead counts range in 32 and 44 positions for the SMT and 32, 44 and 68 positions for the THT version. The standard pin spacing of 1.27mm on the PLCC is designed for standard chips which has the same spacing size.

PLCC is suitable for use in a variety of device types, including memory, processors, controllers and particularly common for read-only memories as it provides an easily swappable socketed chip. Applications range from consumer products through automotive and aerospace.
