Vishay Foil Resistors
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 %
