Packard PMJ124 Start Capacitor

The Packard PMJ124 Start Capacitor is a high-performance, dry electrolytic component designed for intermittent duty in AC motor starting circuits. Engineered with a capacitance range of 124-149 MFD and a voltage rating of 125V (compatible with 110-125V systems), this round capacitor provides the necessary torque to initiate motor rotation in demanding HVACR applications. Built using moisture and oil-resistant molded phenolic resin, the PMJ124 is a direct industry-standard replacement for units like Supco CS124156X110 and 11012, ensuring seamless compatibility across various compressor and pump brands.

For field technicians, reliability is non-negotiable. This unit features standard dual blade terminals (1/4 inch) for quick wiring and is rated for a 3-second start duration with up to 20 starts per hour. Whether you are servicing a residential condenser or a commercial refrigeration unit, the 124-149 uF start capacitor delivers consistent discharge to overcome peak inertia. Its compact 1-7/16" diameter and 2-3/4" height allow it to fit standard mounting brackets, making it a staple for any service truck inventory.

• High Torque Delivery: Provides the critical 124-149 microfarad boost required for 110-125V motor startups.
• Durable Construction: Housed in a rugged phenolic resin case that withstands oil, moisture, and extreme temperatures (-40°C to 65°C).
• Universal Connectivity: Equipped with dual 1/4" male terminals for straightforward integration with existing wiring harnesses.
• Broad Compatibility: Replaces common industry numbers including 11012, 11112, and various Mars or Supco equivalents.
• Safety Rated: UL and cUL recognized, meeting EIA Standard RS-463 type 2 for electrolytic starting capacitors.

Can I use this capacitor if my motor currently has a 124-156 MFD rating?
Yes. In many HVACR applications, the 124-149 MFD range is the designated standard for 110-125V start circuits. As long as the physical dimensions fit and the voltage rating meets or exceeds the original, this unit is a suitable replacement.

What is the difference between MFD and uF on this capacitor?
They are identical. MFD and uF both represent microfarads. The PMJ124 is rated for 124-149 microfarads regardless of which abbreviation is used on the label.

Does it matter if the original capacitor was a different color or material?
No. While many older capacitors used different phenolic resins, the technical specifications (MFD and Voltage) are what dictate performance. The black moisture-resistant housing on this Packard unit is designed to exceed the environmental durability of older OEM parts.
