That means no last-time-buy scramble, no date-code risk from long-shelf-life stock. For BOM planning, this is a stable line item; the only supply constraint is the TO-92 through-hole format, which some high-volume lines have moved away from in favour of SOT-23 or SOT-323.","metaTitle":"LM4040C82ILP Shunt Voltage Reference, 8.192 V, ±0.5%, TO-92","metaDescription":"LM4040C82ILP precision shunt reference from Texas Instruments.

This is the 'C' grade in the LM4040 family; the 'A' and 'B' grades offer tighter tolerances (0.1% and 0.2% respectively) if the application demands better than 41 mV absolute accuracy at 8.192 V."},{"question":"What package does the LM4040C82ILP come in?","answer":"It is supplied in a TO-226-3 / TO-92-3 (TO-226AA) through-hole package, with the supplier device package listed as TO-92-3. The 'Bulk' designation means it ships in loose tubes or bags, not tape-and-reel."},{"question":"What is the cathode current of the LM4040C82ILP?","answer":"The minimum cathode current for regulation is 110 µA. Below this level the shunt output may drift out of specification.
