Procurement Notes
Verify that the ordering suffix matches the required tape and reel packaging format. Confirm the specific reliability level (commercial or MIL-qualified) aligns with project specifications. Ensure the component meets all necessary environmental compliance standards before finalizing procurement orders.
Selection Notes
Select this component when a 5.1 V reference is required in an axial-lead package. Consider the 1500 Ohm impedance limit for noise-sensitive designs. Evaluate thermal derating curves if operating near maximum power dissipation limits.
