Type 944U Polypropylene, DC Link Capacitors

High Current, Low Pro le for Inverter Applications

Type 944U is speci cally designed for use in high power DC

 ltering applications. The low inductance internal construction

utilizes low loss metallized polypropylene for high ripple current

capability. Male or female terminal options oﬀ er design  exibility

in a rugged UL 94VO rated  ame retardant plastic case and resin

 ll. High current ratings and robust mounting  anges make the

944U suited for inverter applications in electric vehicle power

inverters, wind power inverters and motor drives.

Determine ESR at Operating Frequency

Use the 10 kHz ESR from the ratings tables.

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 = ΘCC + ΘCA. In the ratings tables, ΘCA is for still air. For v = 0 to 5 m/s,

multiply ΘCA by [(5 + 17.6(0.10.66)) / (5 + 17.6(v + 0.1)0.66)]

Determine Expected Lifetime

Look up Expected Lifetime on the graph using VA/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.
