Procurement Notes
Verify the specific suffix 'CIZ' against official datasheets to confirm the TO-92-3 package and ±2% tolerance variant. Ensure compatibility with existing through-hole assembly processes. Cross-reference the manufacturer part number directly with STMicroelectronics documentation to validate availability and revision status before procurement.
Selection Notes
Select this component when a through-hole shunt reference is required for 1.225V applications. It is appropriate for designs prioritizing low power consumption over ultra-high precision. Consider alternative packages like SOT-23 if board space is limited, or higher accuracy grades if tighter tolerances are necessary.
Part Context
The TS4041 series consists of micropower shunt voltage references designed for cost-sensitive and space-constrained applications. This family offers various accuracy grades and package options, including surface-mount and through-hole configurations, to support diverse analog circuit requirements while maintaining low power operation.
