Dual Run Capacitor, Round, 35/7.5/440 uF

Mars 12784 – Jard by Mars 35/7.5 MFD, 440V Dual Section Round Run Capacitor The Mars 12784 is a dual-value motor run capacitor designed to support both compressor and fan motor windings in HVAC systems using permanent split capacitor (PSC) motors. It provides 35 and 7.5 microfarads (MFD) of capacitance and is rated for continuous operation at up to 440 volts AC. This capacitor features a metallized polypropylene film dielectric, enclosed in a round aluminum canister with a hermetically sealed, oil-filled design. An internal pressure-sensitive interrupter is included for safety. The non-PCB construction complies with UL and RoHS standards for environmental and operational safety. Technical Specifications Capacitance: 35/7.5 MFD (±5%) Voltage Rating: 440 VAC Operating Frequency: 50/60 Hz Dielectric Material: Metallized polypropylene film Case Type: Round aluminum, hermetically sealed Construction: Oil-filled, non-PCB Safety Feature: Internal pressure-sensitive interrupter Operating Temp Range: -40°C to +70°C Terminals: Dual ¼" male quick-connect terminals Case Height: Approx. 3-7/8 in. Case Diameter: Approx. 2 in. Certifications: UL recognized, RoHS compliant Application Use For use in HVAC condenser units with dual PSC motor circuits Commonly installed in systems requiring combined fan and compressor capacitance values Suitable for OEM replacement or aftermarket maintenance where 35/7.5 MFD at 440V is specified Compatible with standard brackets and mounting hardware Installation Notes Confirm both microfarad values and voltage rating match original equipment Discharge capacitor before handling; use proper PPE and tools Ensure secure terminal connections and verify mounting stability Installation should be performed by a licensed technician to ensure safety and code compliance
