Single Run Capacitor, Oval, 35/440 uF

Mars 12943 – Jard 35 MFD 440V Oval Motor Run Capacitor The Mars 12943 capacitor from the Jard series is a 35 microfarad (µF), 440-volt AC oval run capacitor designed for continuous-duty operation in HVAC systems utilizing permanent split capacitor (PSC) motors. This unit supports motors in air conditioning and refrigeration equipment, including condensers, blowers, and compressors. It features a metallized polypropylene dielectric enclosed in an aluminum case with a built-in pressure-sensitive interrupter to disconnect the capacitor from the circuit in case of failure. The oval form factor allows use in space-restricted compartments. Technical Specifications Manufacturer: Mars Brand: Jard Model Number: 12943 Capacitance: 35 µF Voltage Rating: 440 VAC Frequency: 50/60 Hz Shape: Oval Case Material: Aluminum Dielectric Type: Metallized polypropylene film Terminals: ¼" male quick-connect spade terminals (4-terminal configuration) Temperature Range: -40°C to +70°C Approximate Dimensions: 3.5" H × 2.806" W Environmental Compliance: Non-PCB Application Use This run capacitor is suitable for use in systems requiring 35 µF capacitance at 440 VAC, including: Condenser fan motors Air handler blowers Light-duty refrigeration units PSC motor-driven equipment in residential and light commercial HVAC systems The 440V rating provides additional voltage tolerance, useful in applications subject to higher or fluctuating power supply conditions. Installation Notes Capacitor replacement should follow these guidelines: Disconnect all power and fully discharge existing capacitors before replacement Verify capacitance and voltage ratings match the original component Mount securely using approved brackets or straps Follow the equipment manufacturer’s wiring diagram for correct terminal connection Installation by a licensed HVAC technician is recommended for safety and code compliance.
