Procurement Notes

Verify that the ordering suffix 'Z' corresponds to the TO92 plastic package configuration as specified in the datasheet. Confirm the specific accuracy grade matches the 'E' designation for ±2% precision. Ensure the component meets the required environmental specifications for the intended application environment.

Selection Notes

Select this component for applications requiring a low-cost, space-efficient voltage reference with moderate precision. The TO92 package is suitable for through-hole mounting where surface area is less constrained than SMD options. Consider the 150ppm/°C temperature coefficient for thermal stability requirements.
