Notes

1. Whichever is lower.

2. Heat sink chassis dimensions are requirements per MIL-R-39009/1B:

3. Inductance (L) mainly due to the leads.

4. The resolution limit of existing test requirement (within the measurement capability of the equipment, “essentially zero”).

5. µV/°C relates to EMF due to lead temperature difference.

Note

1. Measurement error ± 0.001 %
