MARS 12386 Run Capacitor
For veteran technicians servicing ductless systems, the MARS 12386 Run Capacitor is a high-reliability component designed specifically for the rigorous demands of mini-split HVAC units. This 4 MFD 450VAC capacitor features a compact, epoxy-sealed rectangular housing, making it an ideal fit for tight electrical compartments where standard oval capacitors fail to seat properly. Rated for continuous duty with a wide operational temperature range of -25°C to 70°C, the MARS 12386 ensures stable capacitance and a low dissipation factor under heavy thermal loads. Manufactured to IEC252-2001 standards, this 4 microfarad run capacitor provides the precise phase shift required for optimal compressor and fan motor torque. Whether you are performing a preventative PM or an emergency breakdown repair, this 450 volt mini-split capacitor delivers the industrial-grade performance necessary to maintain system efficiency and prevent premature motor failure in residential and commercial inverter or fixed-speed systems.
Key Benefits for Technicians:- High-Voltage Tolerance: The 450VAC rating provides a robust safety margin, preventing dielectric breakdown in fluctuating power environments.
- Flame-Retardant Construction: Epoxy-resin sealing ensures the internal elements are protected from moisture and vibration-induced shorts.
- Compact Form Factor: The rectangular "mini" design is engineered for mini-split fan motors and small-frame compressors with limited mounting space.
- Precise Electrical Specs: Features a ±5% capacitance tolerance to keep motor windings within their intended operating parameters.
What are the dimensions of the MARS 12386?
This capacitor typically measures approximately 1-7/8" x 3/4" x 1-3/8", allowing it to fit into the compact control boxes found in most major mini-split brands.
Can I use this to replace a 370V capacitor?
Yes, you can always upgrade the voltage rating (from 370VAC to 450VAC) as long as the 4 MFD capacitance matches the motor's OEM requirement.
Is this compatible with inverter-driven mini-splits?
While inverters use DC conversion for the compressor, many still utilize these AC run capacitors for the indoor or outdoor AC fan motors.
