MARS 11047 Start Capacitor
The MARS 11047 Start Capacitor is a high-torque electrical component specifically engineered to provide the essential phase shift and initial current boost required for starting single-phase fractional horsepower motors in HVACR systems. Featuring a capacitance range of 645-774 Microfarads (MFD) and a dual voltage rating of 110/125Vac, this round start capacitor is designed for intermittent duty cycles, ensuring your compressor or blower motor can overcome high starting torque requirements even in systems with non-bleed TXVs. Its rugged, moisture-resistant plastic case construction eliminates the need for additional insulation while maintaining structural integrity in the harsh environments of an outdoor condenser or refrigeration unit.
For technicians performing field replacements, the MARS 11047 serves as a direct cross-reference for the JARD 11947, Packard PMJ645, and various BMI type 092A units. With industrial-grade 1/4-inch quick-disconnect terminals and an operating frequency of 50/60Hz, this motor start capacitor ensures reliable ignition of the motor windings before the potential relay cycles it out of the circuit. Incorporating this component into your AC repair or maintenance protocol restores original equipment efficiency and prevents the premature failure of expensive compressor motors caused by hard-starting conditions.
Key Benefits- High Starting Torque: Provides the 645-774 MFD boost necessary to initiate motor rotation in heavy-load 110/125V applications.
- OEM Compatibility: Replaces common industry part numbers like MARS 11047, PMJ645, and 11947 with exact technical specifications.
- Durable Construction: Non-polarized aluminum electrolytic design housed in a moisture and oil-resistant round plastic case.
- Standardized Terminals: Features dual 1/4-inch male quick-connect tabs for fast and secure wiring in tight electrical compartments.
What happens if the start capacitor capacitance is too low?
If the capacitance is below the required 645-774 MFD range, the motor may fail to generate enough torque to break inertia, resulting in a humming sound and potential tripping of the thermal overload protector.
Can I use a capacitor with a higher voltage rating than 125Vac?
Yes, in capacitor physics, you can typically use a higher voltage rating (such as 165Vac or 250Vac) provided the microfarad (MFD) rating remains within the 645-774 range, but you must never use a lower voltage rating than the system calls for.
How do I know if my MARS 11047 has failed?
Visual indicators include a blown-out top relief membrane or oil leakage. Electrically, technicians should use a multimeter with a capacitance setting to verify it still reads within its specified range after discharging the component.
