The SFT66T20K391B-F is a motor-run and power supply capacitor in a 2.5" round aluminum case with 4-tine 1/4" quick-connect lug terminals, rated for 660 Vac and 20 µF. It complies with EIA-456-A and is cULus recognized. The capacitor has a standard capacitance tolerance of ±10%, an operating temperature range of 70 °C, and a service life objective of 60,000 hours at 94% survival rate. The case dimensions are 2.91" in height, with at least 0.5" clearance required above for safe operation due to the pressure interrupter mechanism. Dry construction is optional, and the terminal material is tin-plated steel.
