Our take on the ONE Power 45/5-MFD Dual Run A/C Capacitor CBB65B

The ONE Power 45/5-MFD is a round dual run capacitor for air conditioner condenser units: 45 µF for the compressor and 5 µF for the fan motor in one can. It is rated for 440 VAC, 50/60 Hz, and a -25°C to 85°C range, with ±5% tolerance. That dual-section layout is the standard replacement for single-phase condensing units, and it does the same job as any comparable dual run capacitor. Owners of this line rate it well, and the main thing to check is that the microfarad values and can size match the part you are replacing.

Pros
  • Two capacitance values in one round can
  • 440 VAC rating covers common residential condenser voltages
  • Wide -25°C to 85°C operating range
  • ±5% tolerance, standard for motor run capacitors
  • Simple two-terminal wiring
Cons
  • Must match both microfarad values exactly
  • Round can size may not fit every mounting bracket
  • No discharge resistor built in, so discharge before handling
  • No visible failure indicator

What reviewers say

  • 4.7 / 511 ratings

Owners of this capacitor line report it works as a direct replacement and holds up in service. Ratings are high, though the sample is small.

What people mention
  • FitMixedOwners say it drops in when the microfarad values and can size match the old capacitor, and does not when they don't.
  • ReliabilityPraisedBuyers report it keeps the compressor and fan running without early failure.
  • InstallationPraisedOwners describe the swap as straightforward for anyone comfortable working in a disconnect.

Questions and answers

Will this replace my old dual run capacitor?
Only if your old part is also 45/5 µF and rated 440 VAC. Match both values and the can diameter and height before ordering.
What does 45/5 MFD mean?
The 45 µF section runs the compressor and the 5 µF section runs the condenser fan motor. Both share one can and one set of terminals.
Is it safe to install myself?
Only with the power off at the disconnect and the old capacitor discharged. Capacitors hold a charge after power is cut.
Does it work on 370 VAC systems?
A 440 VAC rating covers 370 VAC applications, but confirm the required values on your unit's label first.
What is in the box?
The capacitor itself. Wiring and mounting hardware are not included.
Where is the ONE Power 45/5-MFD Dual Run A/C Capacitor CBB65B cheapest?
