DS9034PC, DS9034PCI:PowerCap

The DS9034PC PowerCap is a snap-on lithium power source for nonvolatile (NV) SRAMs in Dallas Semiconductor's directly surface-mountable PowerCap module base package. After a PowerCap module has been soldered in place and cleaned, the DS9034PC PowerCap is snapped onto the base to form a complete NV SRAM module. The PowerCap is keyed to prevent incorrect attachment and is designed to maintain mechanical and electrical contact with its host module base even during severe mechanical shock and vibration. The DS9034PC is easily removed by inserting a regular screwdriver into the detachment feature and prying gently outward and upward to release the PowerCap from the module base.

Key Features
  • Provides 10 years of battery backup power for NV SRAMs in the PowerCap Module (PCM) package
  • Snaps directly onto a surface-mounted PowerCap module base to form a complete NV SRAM module
  • Attaches after module base has been surface-mounted to protect lithium battery from the high temperatures of reflow soldering
  • Maintains mechanical and electrical connection with module base even during severe shock and vibration stresses
  • Detachment feature allows easy removal using a regular screwdriver
  • Periodic replacement allows NV SRAM module life to be extended indefinitely
  • Compatible with these PowerCap module bases:
    • DS1230YP/ABP/WP
    • DS1245YP/ABP/WP
    • DS1250YP/ABP/WP
    • DS1330YP/ABP/WP
    • DS1345YP/ABP/WP
    • DS1350YP/ABP/WP
  • Do Not Substitute for DS9034PCX
