Procurement Notes

Verify the specific suffix 'FFTC' against the manufacturer's official ordering information table. The datasheet lists variants such as ZXRE4041CF (0.5%) and ZXRE4041DF (1%). Confirm if this suffix denotes a specific tape width, reel size, or environmental compliance grade not explicitly detailed in the standard text.

Selection Notes

Select this component for applications requiring a stable 1.225V reference with minimal quiescent current draw. Ensure the design accommodates the 30µA minimum knee current and verify that the load capacitance does not compromise stability, although the device is designed to be highly tolerant of capacitive loads.

Part Context

This device serves as a direct pin-for-pin compatible alternative to the LM4041 voltage reference series. It belongs to the ZXRE4041 family of micropower references, offering improved performance characteristics while maintaining physical interchangeability with legacy industry-standard components.

Replacement Considerations

The datasheet identifies the LM4041 as a pin-for-pin compatible alternative. Verify electrical parameters such as temperature coefficient and tolerance grades match the original design requirements before substitution.
