DC link capacitors offer high energy density

The type 948D high energy density DC link capacitors target larger inverter systems where high bus voltage, capacitance and ripple current ratings are required for smoothing and filtering. The devices offer 990 to 2700 µF with rms current ratings up to 160 A and voltage ratings of 800 to 1300 Vdc.

The capacitors are housed in a plastic rectangular package that is nearly a cube with 6.5 inch sides. Typical ESR varies from 0.7 to 1.1 mΩ, ambient operating temperature is -25° to 70°C, and inductance is only 42 nH. From $75 ea/OEM quantities with 4 to 10 week lead times.
