Featuring a robust metal shell and metallized polypropylene dielectric, it operates reliably across a wide temperature range (-40℃ to +70℃) and supports both 370V and 440V AC systems. Its compact round design and clearly labeled terminals simplify installation, making it a trusted choice for professionals seeking durable, efficient motor startup and run solutions. ## Description BOJACK Dual run circular start capacitor Ombines two capacitors into one unit. Three terminals on the top are labeled "Herm"/"H" for the compressor motor, "Fan"/"F" for the fan, and "C" for the common line.It will power a compressor motor and a fan motor Model: CBB65（Universal model） Shell material: metal Dielectric Material: metallized polypropylene film Capacity: 40+5uf Tolerance: ±6% Rated voltage: 370V/440V AC Frequency: 50 / 60Hz Safety rated: 10,000 AFC Capacitor dimension: Diameter Height Operating temperature: -40 ℃ to +70℃/-104℉to+158℉ This capacitor is used for start-up and operation of AC motors with frequency of 50Hz/60Hz such as Industrial Grade Replacement for Central Air-Conditioners, Heat Pumps, Condenser Fan Motors, and Compressors.It is small in size, lightweight, heat resisting and anti-explosion. Round capacitor can be used to substitute oval shape one with the same MFD AND Volt specs.A 440 volt capacitor can be used in place of a 370 volt, as it is build better, but the 370 can’t be used in place of a 440 volt. Review: Works great, easy swap out - Easy to replace these and save. HOWEVER. If you dont know electric and how a capacitors work. STAY AWAY. Leave it to Professional. Review: Easy peasy - Perfect product. Easy to install , especially cause I’m just a girl. Fixed my AC issues instantly!

The original in our daughter's unit in Albuquerque is made in China; the disconnect (GE) died yesterday but the capacitor is still working. My take on it is to always keep a spare run capacitor on hand; they are easy to swap out and a very common failure point. You will likely end up with a choice of a Chinese capacitor or none... which would you rather have on a 100F day? Six out of 927 reviews reported lasting less than a year; some of those were "bad out of box." Sounds like a good bet to me. **Q: My capacitor has the same ratings (40+5 uf 40/5 mfd ±6% 370v/440 vac) but only has two terminals. it doesn't have a fan wire. it's a trane xl 16i??** A: Unable to answer because the part was sent back before opening. **Q: Will this work in my rheem rp1530bj1na?** A: Sure will ,if the old one was the same rating **Q: Will this work for a b9457-5600 goodman?** A: If the old one is 40/5 MFD it will work. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great, easy swap out *by G***. on June 18, 2026* Easy to replace these and save.
