With these two new series, Yamaichi is expanding its large family of production use and Test & Burn-in sockets. The two new sockets are for production usage. The CN111S socket was developed especially for modules that meet the DDR2 (Double Data Rate) standard in the SO-DIMM version (Small Outline Dual Inline Memory Module). It is a 200 pin 1.8V version with an installation height of 5.2 mm. The contacts are gold-plated as standard.
