Procurement Notes

Verify the specific suffix BEPA+ corresponds to the required temperature grade (-40°C to +85°C) and plastic DIP packaging. Confirm RoHS compliance status as indicated by the plus sign. Ensure the application circuit matches the specified input voltage limits and load requirements before finalizing procurement.

Selection Notes

Select this component when a fixed 2.5V reference with high precision and low drift is required. The B-grade designation indicates a maximum temperature coefficient of 7ppm/°C, suitable for environments with moderate thermal variations. Consider the A-grade variant if tighter temperature coefficients are necessary.
