Procurement Notes

Verify that the ordering suffix corresponds to the specific resistance value and package type required. Confirm the revision status of the component against the latest datasheet documentation to ensure compatibility with system design requirements.

Selection Notes

Select this component for applications requiring precise, nonvolatile resistance adjustment without external memory. Ensure the total current through terminals A, W, and B does not exceed the specified limits based on the raw resistance value. Verify that the operating temperature range meets the application's environmental conditions.
