H5TQ4G83EFR-RDJ – DDR3 SDRAM – SK Hynix

The SK Hynix H5TQ4G83EFR-RDJ is a 4Gb (512M x 8) DDR3 SDRAM rated for DDR3-1866 in a 78-ball FBGA package, operating at 1.5V. This is a hard-to-find / obsolete memory device available for RFQ at Pacific Component Xchange.

The SK Hynix H5TQ4G83EFR-RDJ is a 4Gb (4,294,967,296-bit) CMOS Double Data Rate III (DDR3) Synchronous DRAM organized as 512M x 8. Built on SK Hynix’s lead-free and halogen-free (RoHS-compliant) process, this device is suited for main-memory applications that require large memory density and high bandwidth. Per the SK Hynix part-number scheme, the -RD speed marking corresponds to a DDR3-1866 (13-13-13) grade.
