The low inductance internal construction utilizes low loss metallized polypropylene for high ripple current capability. Male or female terminal options off er design fl exibility in a rugged UL 94VO rated fl ame retardant plastic case and resin fi ll. High current ratings and robust mounting fl anges make the 944U suited for inverter applications in electric vehicle power inverters, wind power inverters and motor drives. Highlights - Low Inductance - Low Profi le - Low ESR - High Ripple Current - High Voltage Ratings Specifi cations Capacitance Range 33 to 220 µF Capacitance Tolerance ±10% standard Rated Voltage 800 to 1400 Vdc Operating Temperature Range -40 ºC to 85 ºC Maximum rms Current 74A @ 55 ºC Maximum rms Voltage 230 Vac Test Voltage between Terminal @ 25ºC 150% rated DC voltage for 10 s Test Voltage between Terminals & Case @ 25ºC 4 kVac @ 50/60 Hz for 60 s Life Test 5000 h @ 85 ºC, rated voltage RoHS Compliant H ±0.5 mm 5 mm 6 ±0.5 mm 20 ±0.5 mm 84.5 mm 45 ±1 mm 101 mm 71.4 mm 15 mm M8 x 1.25

For operation below 10 kHz, the ESR will need to be adjusted using the following equation: ESR - 31.83/(10C) + 31.83/(fC). Determine Thermal Resistance at Operating Frequency and Air Flow Compute Θ = Θ CC + ΘCA. In the ratings tables, ΘCA is for still air. For v = 0 to 5 m/s, Determine Expected Lifetime Look up Expected Lifetime on the graph using V A/VR and TC = TA + I2 (ESR/1000) Θ The maximum allowed temperature rise is 40 °C and the maximum allowed core temperature is 95 °C.
