Procurement Notes

Verify the specific revision level and manufacturing date code against the datasheet before integration. Confirm thermal interface material requirements and mounting torque specifications for the M4 screws to ensure reliable heat dissipation. Check for RoHS compliance status as older production runs may differ. Ensure driver compatibility with the specified supply voltage ranges and input thresholds.

Selection Notes

Select this module when a combined three-phase inverter and braking resistor control solution is required in a single package. The integrated protection features reduce external component count compared to discrete designs. Verify that the 25 A continuous current rating meets the load requirements and that the 1200 V blocking voltage provides adequate margin for the DC bus voltage. Consider the thermal resistance values for heatsink sizing.
