This low cathode current keeps the overall power dissipation small in battery-powered or thermally constrained designs. That drift matters when the reference sits in a motor-drive enclosure or near an engine bay — the output shifts about 0.15 mV per degree, so a 100°C swing moves the reference by roughly 18 mV. ## SOT-23-3 — small footprint, standard pinout Housed in a three-lead SOT-23-3 (TO-236-3, SC-59) surface-mount package. New designs should consider current-production shunt references.","metaTitle":"LM4041D12QDBZT Shunt Voltage Reference, 1.225V, ±1%","metaDescription":"Obsolete LM4041D12QDBZT precision shunt reference.
