DiversiTech 37125H Run Capacitor

The DiversiTech 37125H is a professional-grade 12.5 MFD 370V oval run capacitor engineered for continuous duty in high-demand HVACR systems. Built with heavy-edged metalized polypropylene film and housed in a rugged, oil-filled metallic case, this motor run capacitor ensures stable capacitance and efficient phase-shifting for single-phase AC motors. Its compact oval profile is designed specifically for tight control box fits where standard round capacitors may struggle. This unit features 1/4 inch quick connect terminals for rapid field installation and is rated for 50/60 Hz applications with a precise +/- 5% tolerance.

For the veteran technician, the 37125H provides high-tier reliability, meeting the 10,000 AFC safety requirement per UL 810 to protect against internal pressure buildup. This replacement HVAC capacitor is built to withstand operating temperatures from -40°C to 70°C, making it a dependable choice for condenser fan motors and small compressors. Its non-PCB construction and dual-voltage compatibility (370VAC) ensure it meets modern environmental and electrical standards for diverse residential and commercial cooling equipment.

• High-Stability Dielectric: Metalized film technology maintains a steady 12.5 microfarad rating under heavy thermal loads.
• Compact Oval Design: Ideal for space-constrained electrical cabinets in air conditioning and heat pump units.
• Enhanced Safety Standards: UL 810 certified with an internal pressure interrupter rated at 10,000 AFC.
• Universal Compatibility: Works across 50Hz and 60Hz systems with a standard 2.17-inch case height.
• Field-Ready Terminals: Standard quad-blade quick-connect terminals facilitate faster service calls.

Can I use a 440V capacitor to replace this 370V unit?
Yes, technicians can safely substitute a 440VAC capacitor for a 370VAC unit if the MFD rating matches, as the voltage rating indicates the maximum allowable tension. However, the 37125H is the direct technical match for 370V specified circuits.

What are the signs of a failing 12.5 MFD capacitor?
Watch for physical oil leaks, top-cap bulging (doming), or a hum from the motor indicating a "failed to start" condition. Testing with a multimeter should show a reading within 5% of the 12.5 uF nominal value.

Is this capacitor suitable for outdoor condenser units?
Absolutely. The 37125H is designed for the high-temperature environments found in outdoor condensing units and is compatible with most HVAC motor run applications requiring this specific capacitance.
