Single Run Capacitor, Round, 35/440 uF

Mars 12743 – Jard by Mars 35 MFD, 440V Round Motor Run Capacitor The Mars 12743 is a single-value motor run capacitor with a capacitance of 35 microfarads (MFD) and a voltage rating of 440 VAC. Designed for continuous-duty operation in HVAC applications, this capacitor supports permanent split capacitor (PSC) motors, including fan motors, blowers, and compressors found in air conditioning and ventilation systems. Manufactured with metallized polypropylene film and encased in a round aluminum shell, the unit is hermetically sealed and features a pressure-sensitive interrupter for safety. The non-PCB construction ensures compliance with environmental and industry safety standards. Technical Specifications Capacitance: 35 MFD (±5%) Voltage Rating: 440 VAC Frequency: 50/60 Hz Temperature Range: -40°C to +70°C Dielectric Material: Metallized polypropylene film Case Type: Round aluminum can Case Height: 3-3/4 inches Overall Dimensions: Approx. 4-1/4 in. height × 1-3/4 in. diameter Terminals: Standard ¼" male quick-connect blades Safety Feature: Pressure-sensitive interrupter Compliance: UL recognized, RoHS compliant, non-PCB Application and Use Intended for use in HVAC systems with PSC motor circuits Compatible with a range of OEM and aftermarket equipment requiring a 35 MFD, 440V capacitor Typically installed in condenser units, air handlers, and packaged systems Suitable for routine service replacement or system retrofit where matching ratings are required Contractor Notes Designed for reliable performance in high-cycle and high-temperature operating conditions Compact size allows for direct fit in standard capacitor brackets Electrical ratings must match system specifications to avoid premature failure Use appropriate safety measures during installation, including capacitor discharge procedures
