This is a high-quality motor run capacitor designed for continuous-duty HVAC applications. It provides the phase shift needed for efficient operation of single-phase motors (such as condenser fan motors or blower motors). It is OEM-quality, UL/CSA recognized, meets EIA-456-A standards, undergoes extensive electrical testing, and is protected to 10,000 AFC for reliable long-term performance.

Key Features

  • Capacitance: 12.5 microfarads (µF / MFD)
  • Dual voltage rating: 370/440 VAC (the higher 440 V rating safely replaces 370 V capacitors)
  • Frequency: 50/60 Hz
  • Shape: Oval (flat-style) aluminum can
  • Type: Single-section motor run capacitor
  • Metallized polypropylene film dielectric with oil-filled construction
  • Quick-connect terminals (typically ¼-inch blade style)
  • Internal pressure interrupter / safety protection
  • Non-PCB construction

Benefits

  • Restores proper motor starting torque and running efficiency when a failed capacitor causes issues like a fan that won’t start, slow spinning, humming, overheating, or short-cycling.
  • Dual voltage rating reduces inventory needs and provides extra dielectric strength for modern high-efficiency systems.
  • Long service life with OEM-level reliability (designed for many years of continuous operation under HVAC conditions).
  • Easy drop-in replacement in most systems that call for a 12.5 µF oval run capacitor (shape mainly affects mounting; electrical values must match).
  • Helps prevent motor damage by delivering the correct phase shift and current.

  • Height: 2.13 inches
  • Weight: approximately 0.4 lbs

(USA-made variant dimensions differ slightly: roughly 5.4 × 2.2 × 1.3 inches, ~0.35 lbs. Always verify physical fit for mounting.)

Compatibility

Universal replacement for HVAC systems requiring a 12.5 µF run capacitor at 370 V or 440 V. Suitable for:

  • Air conditioners (central, window, PTAC)
  • Heat pumps
  • Furnaces and air handlers
  • Packaged units / RTUs
  • Condenser fan motors and blower motors

Commonly used across Carrier, Frigidaire, and many other brands’ equipment. Cross-references include equivalents such as 12.5-440VOVAL, C312R, 12099, 12999, 97F5067 series, CAP-12.5/440 (Hartland), and various Titan Pro / Mars / Packard oval 12.5 µF 440 V units. Match the exact microfarad rating (±5–10% tolerance typically acceptable) and ensure voltage is equal or higher. Shape must fit the mounting bracket/strap.

Note: Always discharge the old capacitor safely before replacement, confirm wiring orientation, and match the motor nameplate rating. Professional installation is recommended for safety.

 

This capacitor is a reliable, widely available replacement part that restores proper motor performance in residential and light commercial HVAC systems. Always verify the exact capacitance and voltage against the original component or motor nameplate before purchase/installation.

Key features
  • Single Run Capacitor — 12.5 MFD rating
  • 370/440 VAC Rated — works in either application
  • Oval Aluminum Can — fits standard mounting brackets
  • Reliable Motor Operation — for compressors and fan motors
