Procurement Notes
Verify the complete part number includes the NOPB suffix to ensure lead-free compliance and specific packaging configuration. Confirm the B-grade designation matches the required 0.2% initial accuracy specification. Ensure the SC-70 package footprint aligns with the target PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when space-constrained designs require a precise shunt reference in a small SC-70 package. It is suitable for applications demanding low operating current and stability under varying capacitive loads. Consider alternative grades if tighter tolerance or extended temperature ranges are necessary for the specific system requirements.
