DESCRIPTION
The DS9034PC PowerCap is a snap-on lithium pow er source for 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 sna pped 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 me chanical shock and vibration. The DS9034PC is easily removed by inserting a regular sc rewdriver into the detachment feature and prying gently outward and upward to release the PowerCap from the module base.
