Run Start Capacitor, Round, 80/7.5 MFD, 440/370

Jard 80/7.5 µF Dual Run Capacitor – 440V, Round Aluminum Case

The Mars 12816 Jard Dual Run Capacitor is engineered for high-performance HVAC applications requiring consistent support for both compressor and fan motor circuits. Featuring a dual capacitance of 80/7.5 microfarads and rated for 440V operation, this capacitor is built for systems operating under continuous-duty and high ambient load conditions.

Constructed with metallized polypropylene film and enclosed in a sealed aluminum case, the 12816 is suitable for rooftop units, split-system condensers, and other HVAC equipment that demands reliability in variable field environments. The round form factor and standard terminal layout make it compatible with a wide range of mounting configurations and OEM specifications.

Key Performance Attributes

Installation Overview

This capacitor is intended for installation by HVAC technicians. Ensure system power is completely isolated before removal and verify specifications match the existing component (µF and voltage). Use appropriate discharge tools to safely remove residual charge. Terminal leads must be properly connected and mounted securely within the capacitor clamp or bracket.

Field Application and Use

Designed for use in systems that require both start and run capacitance within a single enclosure, the 12816 reduces parts count and simplifies system wiring. It supports motor torque stability and reliable voltage control in packaged and split-unit HVAC systems under variable load conditions.

Contractor Benefits

• ✅ Integrated Support for Dual Motors – Eliminates the need for two separate capacitors.
• ✅ OEM Compatibility – Matches common system specs and physical dimensions for easy replacement.
• ✅ Thermal and Mechanical Stability – Designed to withstand vibration and temperature fluctuation typical of field service installations.
• ✅ Reduced Service Downtime – Reliable long-life dielectric minimizes maintenance intervals.
