Packard PRMJ130 Start Capacitor

The Packard PRMJ130 Start Capacitor is a high-performance, dry electrolytic capacitor designed for intermittent duty in AC motor starting circuits. Engineered with a capacitance rating of 130-158 MFD and a robust 330V threshold, this component provides the essential phase shift required to increase starting torque in single-phase motors and HVAC compressor systems. Its round casing is constructed from moisture and oil-resistant molded phenolic resin, ensuring long-term structural integrity in harsh mechanical environments. Featuring standard 1/4-inch dual blade terminals, the PRMJ130 allows for efficient field installation and secure electrical connections. This unit is rated for up to 20 starts per hour with a specialized 3-second start cycle, meeting EIA Standard RS-463 Type 2 requirements. For contractors replacing failed components, this universal start capacitor is the industry standard for ensuring reliable ignition of high-torque loads in refrigeration and air conditioning equipment.

• Durable Construction: The phenolic resin housing protects the internal electrolytic components from oil and moisture common in HVACR environments.
• Optimized Torque: Specifically sized at 130-158 microfarads to provide the necessary boost for heavy-duty motor starting.
• Standardized Fit: Round form factor (2-1/16" diameter) ensures compatibility with most existing mounting brackets and terminal configurations.
• Wide Temperature Range: Certified to operate in extreme conditions from -40°F to 149°F (-40°C to 65°C).

What is the difference between this and a run capacitor?
The PRMJ130 is a start capacitor designed for high-torque, momentary operation during initial power-up. Unlike a run capacitor, which stays in the circuit continually, this unit must be cycled out via a relay once the motor reaches speed.

Can I use a capacitor with a higher voltage rating?
Yes. In HVACR applications, you can replace a 125V or 250V capacitor with this 330V unit, provided the MFD range (130-158) matches the motor manufacturer's specifications.

Is this compatible with common compressor brands?
Yes, this is a universal replacement part that meets UL and cUL recognition standards for a variety of HVAC refrigeration and single-phase motor brands.
