A round dual run capacitor that packs a 45 uF compressor section and a 5 uF fan section into one can, rated for 370 or 440 VAC. It has three labeled terminals (HERM, FAN, C) and works in air conditioners, heat pumps and condenser units. The ±6% tolerance and -40°C to 70°C range are typical for this class; the main thing to check is that its 2.36 in. diameter and 3.15 in. height fit your mounting bracket. It is a standard replacement part, so it competes on matching specs and build rather than features.

This is a CBB65 round dual run capacitor rated 45+5 uF at 370/440 V AC. It combines two capacitors in one unit, so it can run a compressor motor and a fan motor at the same time. It is designed for HVAC equipment including air conditioners, heat pumps, and condenser units.
It has three labeled terminals: HERM for the compressor, FAN for the fan, and C for the common line. It replaces any round or oval dual run capacitor with matching 45/5 uF capacitance and 370 V or 440 V specifications. Check capacitance, voltage, and physical dimensions before buying.
Signs a capacitor may need replacing include an outdoor fan that does not spin or turns slowly, and a compressor that struggles to start. A humming or buzzing A/C unit that does not start is another sign, as is a case that is swollen, bulging, or leaking oily fluid.
