Procurement Notes
Verify the specific suffix IDBZR corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the C-grade accuracy specification meets the circuit tolerance requirements. Ensure the operating temperature range aligns with the intended industrial environment constraints before finalizing procurement orders.
Selection Notes
Select this component when a fixed 1.23 V reference is required in a compact SOT-23-3 footprint. It is suitable for designs needing ±0.5% initial accuracy and operation up to 12 mA cathode current. Consider the 100 ppm/°C temperature coefficient for thermal stability needs within the -40°C to +85°C range compared to higher precision or lower drift alternatives.
Part Context
This part belongs to the LM4041 series of micropower shunt voltage references. The series includes adjustable variants and other fixed voltages, utilizing Zener-zap trimming for precision. The LM4041C12IDBZR represents the fixed 1.23 V option with C-grade accuracy, designed for cost-sensitive applications requiring reliable performance in space-constrained surface-mount layouts.
