Not to exceed power rating. 0.15 µV/°C maximum (lead effect) NOTES: 1. Maximum is 1.0% A.Q.L. standard for all specifications except TCR. Typical is a designers reference which represents that 85% of the units supplied, over a long period of time, will be at least the figure shown or better. 2. Whichever is lower. 3. Heat sink chassis dimensions and requirements per MIL-R-39009/1B: Dimension Inches mm L 6.00 152.4 W 4.00 101.6 H 2.00 50.8 T 0.04 1.0 4. Inductance (L) due mainly to the leads. 5. The resolution limit of existing test equipment (within the measurement capability of the equipment, “essentially zero”). 6. µV/°C relates to EMF due to lead temperature difference.
