Mars MMMINICAP20 Motor Run Capacitor 12.5 Mfd 370/440 Vac

Product Description

The MARS MMMINICAP20 is a universal motor run capacitor rated at 12.5 microfarads (MFD) and designed to operate at 370/440 VAC, 50/60 Hz. It measures 1.75 inches x 3 inches and is built to OEM performance standards for reliable continuous-duty service in motor circuits. The internal modular construction promotes cooler operation and more efficient heat dissipation compared to single-wound, multi-tapped designs. Every unit undergoes full inspection including overrun testing at 700 VAC, 60 Hz for one minute before leaving the factory. Licensed HVAC technicians and motor service professionals install this capacitor in single-phase permanent split capacitor (PSC) motor applications.

The MMMINICAP20 is suited for residential and light commercial HVAC applications where a compact, universal-fit run capacitor is needed. Its universal design makes it appropriate for condenser fan motors, blower motors, and compressor run circuits that require a 12.5 MFD rated capacitor. The dual voltage rating of 370/440 VAC allows installation across a wide range of equipment without requiring a voltage-specific part. Technicians commonly use this capacitor as a direct replacement during service calls to restore motor performance quickly and reliably.

Key Features

• 12.5 MFD rating at 370/440 VAC, 50/60 Hz for broad voltage compatibility
• Overrun tested at 700 VAC, 60 Hz for one full minute, verifying performance under extreme conditions
• Internal modular construction enables cooler running and improved heat dissipation
• Single-post failure does not render the unit unusable, unlike single-wound multi-tapped capacitors
• Manufactured to OEM performance and reliability standards
• Constructed to current international environmental standards

Compatibility

Designed as a universal OEM-style replacement motor run capacitor for single-phase PSC motors in residential and light commercial HVAC equipment requiring a 12.5 MFD, 370/440 VAC rated capacitor.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect and lock out all power to the unit before servicing capacitors, as run capacitors store a lethal charge even after power is removed and must be safely discharged before handling. Verify the MFD rating and voltage rating of the replacement match or exceed the original equipment specification before installation. Follow all applicable local electrical codes and NEC guidelines when servicing motor run capacitor circuits.
