Mars 12169 Dual Section Motor Run Capacitor – 70/10 MFD, 440V
The Mars 12169 is a dual-section motor run capacitor rated for continuous operation at 440 volts AC. It features capacitance values of 70 and 10 microfarads, supporting two independent motor windings within HVAC systems. This component is commonly used in condenser fan motors and compressor applications where dual ratings are required.
The oval metal case is designed for installation in standard capacitor brackets or straps, and the terminals are configured for quick-connect wiring. The capacitor is non-PCB and built to meet or exceed UL and EIA-456A standards for safety, endurance, and reliability in demanding conditions.
Product Specifications:

Application Notes:
For use in single-phase motor circuits requiring dual capacitance values, such as compressor/fan motor combinations.
Designed for use in commercial and residential HVAC systems.
Always verify microfarad and voltage ratings match system requirements prior to installation.
Proper discharge and handling procedures must be followed during installation or replacement to avoid injury or equipment damage.
Contractor Considerations:
Mars capacitors are engineered to handle sustained electrical loads and ambient conditions typical of rooftop units, condensers, and package systems.
Units offer stable capacitance over temperature fluctuations and extended duty cycles.
Suitable for service stock replenishment and multi-system compatibility due to standardized terminal layout and voltage rating.
