MARS 12116 Run Capacitor

The MARS 12116 Run Capacitor is a high-performance 100 MFD 370V round run capacitor specifically engineered for heavy-duty HVACR applications. Designed for 50/60 Hz single-phase motors, this OEM-grade capacitor meets rigorous EIA-456 A standards, offering a reliable 60,000-hour operational life. For technicians replacing older 100 microfarad 370Vac units, the MARS 12116 provides a seamless fit with its 2.5-inch diameter and 4.75-inch case height. The non-PCB and oil-filled construction, housed in a durable aluminum case, ensures optimal heat dissipation and safety via an internal physical interrupter. Whether you are servicing air conditioning condensers, blower motors, or phase converters, this UL-recognized motor run capacitor maintains the necessary phase shift to keep inductive loads running efficiently. Professionals can rely on its wide temperature range of -40°C to +70°C for stable performance in extreme environments across both residential and commercial cooling systems.

Key Benefits:

• High-Efficiency Performance: Specifically rated as a 100 MFD 370V component to support high-torque motor demands and continuous duty cycles.
• Durable Construction: Built with an aluminum case and non-PCB, oil-filled dielectric for superior thermal management and a 60,000-hour service life.
• Safety Compliance: Features a physical pressure interrupter and meets EIA-456 A standards, providing peace of mind during high-stress operations.
• Direct Compatibility: Replaces common industrial part numbers like Supco CR100X370R and Titan PRO TRC100, fitting standard round run capacitor mounting brackets.
• Universal Application: Suitable for a wide range of HVACR motor capacitor replacements in blowers, fans, and compressors.

Common Questions:

• Can I use a 440V capacitor to replace this 370V unit? Yes, you can always upgrade to a higher voltage rating (e.g., 440V) as long as the 100 MFD capacitance and physical dimensions remain the same. However, you cannot use a lower voltage rating.
• What does the physical interrupter do? The interrupter is a safety feature designed to disconnect the capacitor internally if internal pressure builds up, preventing the casing from rupturing.
• How do I confirm if my capacitor is failing? Check for a bulged top, leaking oil, or use a multimeter to verify if the microfarad rating has drifted more than 5-10% from the nominal 100 MFD value.
