Motor Run Capacitor 45MFD

Motor Run Capacitor 45MFD – Reliable Power for Efficient Performance

The 45 MFD Motor Run Capacitor is a critical component for the continuous operation of various electric motors, especially in HVAC systems, air conditioners, compressors, and other industrial and residential equipment. Designed to improve motor efficiency, extend operational lifespan, and reduce power consumption, this capacitor offers dependable performance where it matters most.

Whether you’re replacing a faulty unit or installing a new system, this 45 microfarad (MFD) motor run capacitor ensures your motor runs smoothly, quietly, and efficiently under continuous load. Manufactured with high-grade materials and rigorous quality control standards, it offers excellent thermal stability, corrosion resistance, and long operational life.

Key Features:

• Capacitance Rating: 45 MFD (Microfarads)

• Voltage Range: Available in 370V and 440V AC models

• Frequency: 50/60 Hz

• Construction: Metallized polypropylene film for high reliability

• Case Material: Rust-resistant aluminum canister

• Terminal Type: Standard ¼” quick-connect terminals

• Operating Temperature Range: -40°C to +70°C

• Compliance: UL Recognized, RoHS Compliant

Performance You Can Trust

This 45 MFD capacitor is a motor run capacitor, meaning it remains in the circuit while the motor is operating. Unlike a start capacitor, which only works during startup, a run capacitor supports the motor throughout its operation, providing a continuous boost in torque and efficiency. This results in better energy usage, reduced wear and tear, and quieter motor operation.

Its robust internal design utilizes metallized polypropylene film, which allows for self-healing in the event of a dielectric breakdown—extending the life of the capacitor and minimizing maintenance needs.

Common Applications:

• Central air conditioning systems

• HVAC compressors

• Refrigeration units

• Heat pumps

• Blowers and fans

• Pool and spa pumps

• Industrial motors

If your motor is running slower than usual, humming, or struggling to start, a faulty capacitor might be the cause. Replacing it with a high-quality 45 MFD motor run capacitor can often restore full function without the need to replace the entire motor or system.

Durable and Safe Construction

The capacitor’s cylindrical aluminum casing is both corrosion- and heat-resistant, making it suitable for indoor and outdoor use. The sealed top and pressure-sensitive internal interrupter ensure safety by disconnecting the capacitor in the event of a failure or pressure buildup. Each unit is tested for leakage current, capacitance tolerance, and insulation resistance, ensuring reliable operation even under high-load conditions.

Easy Installation

Thanks to clearly marked terminals and a compact design, the 45 MFD motor run capacitor is easy to install—even in tight or hard-to-reach spaces. Most standard HVAC and electric motor systems will accept this size and terminal configuration, making it a convenient drop-in replacement for OEM parts.

Before installation, always ensure the voltage and microfarad rating match your existing unit, and follow proper safety precautions.
